ExperienceMicrochip/Atmel, San Jose, CADirector, Supply Chain Central Planning Jun 14 - Present Supply Chain Planning (Front End):

- Responsible for corporate-wide wafer starts, which supports $1B+/yr business- Develop and propose wafer loading strategies and plans for in-house fabs and external foundries- Control and manage inventory levels to meet company targets- Ran routine wafer loading review meetings for Atmel CEO and executives- Provide long-term and short-term production and capacity plans- Identify potential production-related issues/concerns and propose solutions- Help investigate SAP SNP system issues and propose fix plans- Responsible for backend capacity analysis to early detect potential capacity issues, and ensure capacity setup is

correctly reflected in SAP SNP systems Master Data Management:

- ERP and SNP system master data integrity for Global Planning, through creation, change, audits and enhancements

- Converting manufacturing data inputs into usable SAP material set up parameters - Routine (daily, weekly, monthly, quarterly) data integrity audits in SAP ECC and SNP

Monolithic Power Systems, San Jose, CADirector, Planning and Production Control Oct 10 – Jun 14 Supply Chain Planning:

- Coordinated Sales, Marketing, Finance, Engineering, and Production to achieve Company’s goals- Managed the entire semiconductor supply chain to meet customer demands- Responsible for all production and delivery related issues- Responsible for all loading plans (fab, probe, assembly, final test) for all suppliers, including strategic

partnerships with major suppliers- Designed and implemented automatic planning system (Adexa SCP)

Inventory Control:- Provided long-term loading and inventory plan for executive reviews- Controlled and achieved inventory targets based on company’s strategies- Managed reserved inventory

Capacity Planning:- Routine review for internal and external capacity requirements and constraints- Coordinated capacity allocations and expansions with related departments- Planned and managed in-house test floor capacity

Demand Analysis: - Routine meeting with Sales/Marketing to rationalize demands- Implemented waterfall analysis to manage forecast changes

- Analyzed customers’ cycle time patterns and “risk factors” by customer base, volumes, and other inputsAlpha and Omega Semiconductor, Sunnyvale, CADirector, Operations Management Mar 05– Oct 10 Corporate Strategic Planning:

- Coordinated Marketing, Engineering, and Manufacturing to create long-term manufacturing plans- Managed production to accommodate Marketing/Engineering product transition plans- Provided algorithms for production plans that could consider high-margin products and strategic accounts for

long-term profitability Demand Planning:

- Defined and developed the functionality for this new department. Main work was to rationalize demands through multiple checks such as inventory levels, POS history and forecast, product transitions, and other information, then provided consolidated demand requests to Planning department

Distributor management:- Implemented different techniques to rationalize the forecast, and find out potential issues for upsides and

downsides- Considered channel inventories, forecast, and order situations to validate distributors’ backlogs. The system

helped prepare buffer inventory at channels, and prevent stuffing the channels In-house IT Planning system:

- Designed and implemented the home-grown planning system- Implemented automatic real-time delivery commitment in system

Helped set up foundations for Oracle ERP/ASCP implementations

Vishay Siliconix Inc., Santa Clara, CAProgram Manager, Strategic Planning for Worldwide Manufacturing May 98-Mar 05 Overall Equipment Efficiency (OEE):

- Lead engineers to develop OEE systems for all major fab equipment- The system automatically created weekly reports to cover 100+ machines- Reduced wafer cost and increased productivity through Overall Equipment Efficiency (OEE) improvement- Stepper throughputs increased by 100% in 2 years

Equipment Automation: - Lead engineers to develop semiconductor equipment automation systems, which covered more than 100

semiconductor machines- The system is running on a 24x7 basis with more than 99% reliability- Scraps in diffusion area reduced by 90%+ after implementation

C ycle Time Reductions: - Defined standard metrics for measuring cycle time performances for worldwide frontend and backend

locations. - Designed tools and concepts of cycle time reduction. The results showed all factories achieve 20%-50%

cycle time reduction while maintaining the same production level Semiconductor Manufacturing Benchmarking: Provided benchmarks for semiconductor manufacturing and

proposed how to make improvements in major manufacturing areas

Leachman and Associates, Berkeley, CAConsultant May 95-May 98 Established procedures, databases, and systems for on-going, routine measurement of overall equipment efficiency

(OEE) and capacity of key semiconductor equipment types Increased productivity up to 100% for some equipment with the help of OEE system

Competitive Semiconductor Manufacturing (CSM), UC BerkeleyTeam Member Mar 94- May 98 Developed comparative benchmarks and performed comparative studies of the world's best semiconductor plants

to identify world-class managerial, organizational, technical, and human resource practices Participated in CSM site visits to various semiconductor fabs worldwide
