Industry 4.0 Application Scenarios

“robustness and adaptability”

Apparently: CPS is a foundation of resilient manufacturing – but …

… what is a CPS?

Wikipedia:

A cyber-physical system (CPS) is a system of collaborating computational elements controlling physical entities. Today, a precursor generation of cyber-physical systems can be found in areas as diverse as aerospace, automotive, chemical processes, civil infrastructure, energy, healthcare, manufacturing, transportation, entertainment, and consumer appliances. This generation is often referred to as embedded systems. In embedded systems the emphasis tends to be more on the computational elements, and less on an intense link between the computational and physical elements.

Industry 4.0 Cyber Physical Systems

Industry 4.0 Many Open Questions

“… 85% of the experts are convinced that most German companies have no clear understanding of Industry 4.0”

Industry 4.0 Many Open Questions

“32% of the managers claim that they have not yet heard or read about Industry 4.0”

Semiconductor Manufacturing … what comes to mind

- high growth trend (9% over the last 20 years)

- high volatility

Automatis ierte Prozesskontrolle (APC)

Objective: Ensure high productiv ity and product quality

Fundamental goals of APC (“Advanced Process Control”)

to apply measures for process control close to the process

to automate control actions

Typical APC methods (SEMI E133):

SPC, FDC, FP, RtR, VM, PdM

Basis for APC:

Metrology data

Data from equipment & processes

Logistics data

APC in semiconductor manufacturing „Big data“ and Advanced Process Control

Statistical Process Control

Fault Detection and Classification

Fault Prediction

Run-to-Run Control

Virtual Metrology

Predictive Maintenance

Predictive Maintenance (PdM)

APC in semiconductor manufacturing Examples for productivity enhancement by APC

Real-time control of plasma processes by integrated OES

Higher productivity at equipment level

Prediction of maintenance events by PdM

Optimized tool operation and maintenance planning

Prognosis

Real time tobreakdown

new used broken

Ion source

Prediction of quality parameters by v irtual metrology

Tight process control by “measuring” every wafer

Prediction of etch depth by VM - predicted data vs. metrology results

Flexible sampling and predictive scheduling with W@R* indicator

Best quality control with minimized number of measurements

* Wafers at risk = amount of uncontrolled wafers

APC in the Backend: Wedge-wedge wire bonding

Development of PdM system for optimized wedge tool usage

Tool tip with contamination: Correlate wear status with quality parameters and

equipment parameters

APC in semiconductor manufacturing Estimation of benefits – RoI

Investment assessment for APC in semiconductor manufacturing

Identification of economic effects from APC – possible savings and cost

Development of models to calculate economical figures of merit, e.g., RoI, payback period

FMEA to identify and quantify new risks from the introduction of APC

APC in semiconductor manufacturing Structured approach for development and deployment

CPS are based on connectivity (IoT)

CPS run complex analytics

CPS extract knowledge from raw data

A cyber-physical system is characterized by a physical asset, such as a machine, and its digital twin; basically a software model that mimics the behavior of the physical asset. In contrast, the IoT in common parlance is generally limited to the physical assets, not their digital models.
