Yokkaichi operations has been actively promoting the reduction of environmental impact. In addition, focusing on nature conservation activities.

semiconductor production. However, we relax the clean level in other parts to reduce total electric power consumption. We are also implementing "energy-saving in power supply"　by improving efficiency of the power supply devices and reducing the air-conditioning systems in the plant, and making efforts for "more efficient production line." For example, we have constructed a workpiece-transport system where each workpiece in a dedicated small container is freely transported between the fabrication facilities, searching for the optimum production line. In this system, we avoid wasteful use of the energy supplied to the production line and dramatically improve productivity.　Yokkaichi Operations may be called a plant where cross-departmental energy-saving technologies are proactively introduced.

Development of activities focused on environment, CSR and communication

In Yokkaichi Operations, we are actively developing the initiatives of “minimize waste”’ and “turn waste into resources,” and have achieved effective results in “3R activities.” We reduce the amount of the chemical liquid used in the lithography process and reduce new purchase of chemical liquid for cleaning. About hydrofluoric acid generated in the production process, we have introduced a recovery system where the component after decomposition is solidified as calcium fluoride. We sell it to a dealer together with highly concentrated hydrofluoric acid as valuable materials for new fluorine products.We are not only working on the environmental activities inside the plant, but also positively promoting biodiversity activities in the

Yokkaichi Operations, the world-leading NAND-type flash memory production base

Toshiba Semiconductor & Storage Products Company, Yokkaichi Operations is one of the largest semiconductor plants in the world. NAND-type flash memories, which are embedded in various digital products, such as rapidly spreading smartphones, are sent out to the world from here in Yokkaichi. Yokkaichi Operations is a production plant with state-of-the-art production equipment, and also development base. At the same time, it is “a plant that actively promotes efforts to reduce environmental impact,” sincerely tackling global environmental problems facing mankind. We have expanded fabrication facilities since 2005. The second phase construction of No.5 fabrication facility (Fab 5) was completed in summer 2014. At Fab 5, we aim to reduce CO₂ emissions by about 13% compared to Fab 4. Furthermore, for the mass production of three-dimensional structure NAND-type flash memories (3D memories), we started rebuilding Fab 2, and it will be completed in summer 2015. At the newly-rebuilt Fab 2, we aim to reduce CO₂ emissions by about 15% compared to Fab 5. We take various initiatives for environmental protection, including preventive measures addressing global warming, chemical substance reduction, and biodiversity activities, so that Yokkaichi Operations deserves one of the top state-of-the-art plants in the world.

Energy-saving’ measures adopted everywhere in production line in plant

One characteristic example of the CO₂ emission reduction initiatives in Yokkaichi Operations is “energy-saving in production process.” We always secure the highest clean level inside storage boxes and at production devices for wafers, essential components for

surrounding area of the plant. Using "quick assessment of biodiversity potential" adopted by Toshiba group, we quantitatively assess the green space and water system within a 2-km radius from the plant, and perform environmental conservation activities jointly with local governments and experts. We are developing new efforts for nature conservation through activities such as participation in satoyama creation led by local community, and "planting 1.5 million trees" by local Toshiba group.In addition, we devote ourselves to CSR focusing on environmental conservation, implementing various activities in cooperation with the local community. The activities include periodical liaison meetings with local residents, environmental education programs (developed in collaboration with local government) at neighboring elementary schools, and participation in exhibitions. These are good opportunities to let people know widely about the environmental activities of Yokkaichi Operations and increase communication with stakeholders. Such efforts bear fruit one by one, and deepen trust between neighboring communities and the plant..

Next generation semiconductor memories sent out from plant actively promoting environmental impact reduction

Yokkaichi Operations, where we are actively promoting the world-class project of environmental impact reduction, produces NAND-type flash memories. These memories themselves contribute to lower electric power consumption of various products. Especially, SSDs have no drive section unlike HDDs, and remarkably reduce power consumption. Therefore, SSDs are rapidly applied to data centers that are playing a major role in the era of using big data, and to the medical equipment field. The low power consumption of memories is achieved by cutting-edge process technology. As a nanofabrication technology for the reduction of memory cell area, we have adopted ultrafine 15nm process technology. With the multi-level cell technology that allows one memory cell to store two bits or more data, and the technologies of chip thin-grinding and thin multi-layer stacking, we have drastically reduced the cost and power consumption per memory capacity.Furthermore, we are working on the development of next generation semiconductor memories with greatly increased storage capacity achieved by forming the existing NAND-type flash memories into the three-dimensional structure.

We developed the worldʼs first 48-layer three dimensional stacked cell structure flash memory called BiCS in March, 2015.We are also readying for mass production in the new Fab2 at Yokkaichi Operations. The new fab2 is now under construction and will be completed in the first half of 2016.The next generation semiconductor memories with 1TB capacity, 16 times as large as that of the existing products, are planned to be put to practical use within 4 years. To achieve that, we will introduce cutting-edge production equipment and switch to the efficient BiCS memory mass production.As described above, using all sorts of technologies, we perform both the environmental and business activities at the same time in Yokkaichi Operations. The energy-saving technology and improved productivity in the plant lead to cost reduction and higher competitiveness in product price. The design and process technologies of the low-power-consumption semiconductors give birth to next market-leading products. In Yokkaichi Operations, further advance automation of the production process to increase productivity to the maximum so that our employees are shifted to higher-value-added sectors, where they can improve the ability of product development and polish technical skills. Here, “environment” is one of the most important key words. We all the members will continue to move forward so that the environmental conservation activities of Yokkaichi Operations will be recognized around the world.

Every year, we conduct a Toshiba Comprehensive Environmental Audit. With an emphasis on workplace management, the auditors examine achievement levels of the Toshiba Group’s Environmental Action Plan for energy saving, reduction of chemical substance emissions, reduction of waste, etc.

workplace management at 19 facilities e.g. checks of wastewater treatment equipment, recycling, and chemicals warehouses and facilities that use chemicals, effectiveness of emergency drills, compliance, measurement control of legally controlled substances, 4S (sorting, straightening-up, sanitation, and sweeping) approach, implementation status of employee education, etc.Having structured an EMS in accordance with ISO14001, Yokkaichi Operations annually conducts internal environmental audits of the EMS to improve our environmental performance. Additionally, we are also subject to an annual ISO 14001 external examination, where we can ensure compliance of the EMS with ISO14001 standards and continually improve our environmental management activities.

Since 1993, the Toshiba Group has been conducting regular environmental audits covering its sites including Yokkaichi Operations annually, through the Toshiba Comprehensive Environmental Audit system established by the Toshiba Corporation.An audit team consisting of qualified internal members conducts this audit for 2 days, based on the following principles: “3 Zen (all) approach," “3 Gen (actual) approach," and Visual control (management to watch and show) approach. The “3 Zen (all) approach" is to promote management of all facilities in all areas by all employees, and the “3 Gen (actual) approach" is to emphasize measurement of the actual situation of actual items at actual plants. The audit items cover 1) environmental management, 2) legal compliance and 3) plant management, or more specifically,

Toshiba’s Comprehensive Environmental Audit

We conduct internal environmental audits covering all the departments at Yokkaichi Operations. The auditors are certified by an external organization.To identify an issue to be improved, they check that activities in each department meet our environmental policy, or that each department is proactively promoting its activities to achieve environmental objectives and targets. We actively publicize excellent activities to other departments in order to raise the standard of our activities as a whole.

ISO14001 External ExaminationAn external certification organization conducts the audits, of which there are two types. In the surveillance audit, conducted annually, checks are made on the validity of the EMS and its maintenance. In the recertification audit, implemented once every three years, the continual effectiveness of the overall EMS is comprehensively verified.In fiscal 2014, the Toshiba Corporation Semiconductor & Storage Products Company underwent a surveillance audit and we, Yokkaichi Operations, had no matters pointed out.

Examples of Measures to Prevent Environmental Pollution

Emergency DrillsIn readiness for emergencies, we have standardized response procedures for selected facilities and operations with high environmental risks assumed. Emergency drills are periodically carried out to maintain readiness so that swift action can be taken in the event of an emergency, and we can ensure their effectiveness and review our response procedures.

We have introduced environmental accounting to quantify costs related to environmental protection and their benefits and to utilize the data as guidelines for environmental protection activities. Classification and calculation of environmental protection costs are based on the “Environmental Accounting Guidelines 2005” specified by the Ministry of the Environment as well as Toshiba Group’s own specifications. The costs totaled approximately 14 billion Japanese yen in fiscal 2014.

Environmental Risk AssessmentWe verify that no environmental impact has been detected, by assessing the long-term environmental risks of the surrounding area through ecosystem surveys, odor surveys, chemical substance surveys, etc. of the nearby river whenever environmental impacts of Yokkaichi Operations are likely to change significantly, for example, when a manufacturing building is established.

Wastewater Treatment FacilitiesAcid and alkali discharged from Yokkaichi Operations are collected with wastewater treatment facilities and released into the river through the abatement process.

Overhead Pipes/Double Piping at the JointsPipes are arranged on racks instead of being laid underground, in order to prevent any chemical leakage polluting the soil. Piping at the joints is doubled to enable monitoring of liquid leakage.

Dike for tankThe underground relay tank in the clean room building, by providing in the basement and not outdoors, we are committed to preventing the spread. Even if leaking drainage in the tank, we will be able to prevent the spread of the spill by placing the dike.

Management of Usage and Emissions of Chemical Substances

Chemical substances may cause serious environmental pollution and, as a result, adversely affect human health and the ecosystem if inappropriately managed. Our basic policy on chemical substances is:-to minimize the use of hazardous chemical substances,-to reduce the use of chemical substances and switch tosubstitutes with less environmental impact, and-to ensure the appropriate management of chemicalsubstances.We aggregate the amount of chemicals handled monthly bymeans of a Chemical Substance Control System. Using thisdata, we aim to monitor the amount of chemical substancesreleased into the air and water area, and the amounttransferred as waste.

*1 *2 *3Amountremoved

Amountrecycled

*1 Amount consumed is the amount of a substance used in or associated with a product and shipped out of the Operations.*2 Amount removed is the amount of a substance transformed into other substances by neutralization, decomposition or reaction treatment performed at the Operations.*3 Difference between the amount of waste transferred and the amount recycled depends on whether waste is processed with charge or without charge. For example, when waste disposal is outsourced with charge even for recycling purposes, the amount is considered as the amount of waste transferred.

Example of reducing usage of chemical substances

Yokkaichi Operations uses a large amount of sulfuric acid in the semiconductor manufacturing processes. Meanwhile, there are many problems in the recycling of sulfuric acid. So, we reduced consumption by changing the manufacturing process, and introduced the technology to recycle sulfuric acid.Moreover, we reduced a large amount of diluted hydrochloric acid by reusing sulfuric acid discharged from the manufacturing process instead of hydrochloric acid as a pH adjuster for chemically treating discharged water in the factory. As a result, we reduced the consumption of the chemical solution about 4,000 tons/year by these measures, we will promote the technical development to reduce the environmental impact in the future.

In the semiconductor manufacturing process, we use greenhouse gases such as perfluorocarbons (PFCs), as well as a large amount of energy.To address global warming, we have been developing various energy-saving measures for manufacturing equipment and power facilities, and reducing our greenhouse gas emissions.

A large amount and various kinds of greenhouse gases are used in the production processes: the P-CVD (plasma CVD) process where insulating films are formed on wafers, and the DRY (dry-etching) process where wirings and contact holes are formed by nanofabrication technology.We regard “emission reduction from the source” as the key to the reduction of greenhouse gas emissions, and have implemented many measures shown in the table below: Measure 1 is installing a detoxifying device to the production equipment that uses greenhouse gases. The device decomposes greenhouse gases into ones with small warming decomposes greenhouse gases into ones with small warming potential and emit them.

This measure decomposed almost all the greenhouse gases, and was highly effective in reducing them. Measures 2 through 7 are shortening the cleaning time of the reaction chamber in the production device by device modification and other improvements. These measures suppressed the amount itself of the greenhouse gases used. Measure 8 is omitting wasteful parts of the wafer processing conditions. The measure reduced the amount of the greenhouse gases used. Although the reduction effect of Measures 2 through 8 is rather small, they lead to product cost reduction. We will continue to promote measures linked to such product cost reduction.

Example of reducing total GHG emissions：Efforts to reduce GHG emissions in manufacturing equipments

precisely by installing the air intake near the manufacturing area (in the figure: Upper floor). Based on this examination result, we realized big energy saving per one manufacturing equipment by downsizing the air conditioner.We are working to save the energy by supplying power appropriate to the ability of the manufacturing equipments, while facilities section cooperates with a manufacturing section.

We introduce many manufacturing equipments in the Yokkaichi Operations and produce semiconductor products. Each semiconductor device operates day and night while consuming electricity, gas and water. With the micronization and the advancement of products, it is required to control the power of the manufacturing equipments more precisely year by year.Manufacturing equipments may have air conditioners to satisfy this demand level. We worked on reducing energy in the manufacturing equipments of the lithography process by downsizing an air conditioner incorporated in manufacturing equipments.Until now, air controlled temperature-humidity was sent into manufacturing equipments by inspiring the atmosphere of the facilities area (in the figure: Lower floor) where an air conditioner installed in.
