Abstract
With MEMS devices providing mission critical functionality in more
applications, the need for comprehensive cost simulation is paramount. Due to
their non-standard manufacturing process, the cost of MEMS devices can be
difficult to estimate. Components such as accelerometers, pressure sensors,
inkjet heads or micromirrors involve very different process steps. This is why
a specific and very flexible tool is required for their cost estimation. Yole
Developpement, leader in the analysis of MEMS applications and markets, and
System Plus Consulting, leader in cost analysis of electronic products have
joined forces to provide this unique MEMS Cost Simulation Tool (CoST).
The multiple benefits of MEMS CoST
- The functions of MEMS CoST:
- Possibility to run the cost simulation for a variety of different
conditions (region, clean room class, process type, etc)
- Integrated Equipment, Wafer & Materials Databases
- Very high flexibility:
- MEMS CoST allows the user to enter any MEMS process flow
- The manufacturing process flows are created dynamically in a friendly
hierarchical view where each process step can be moved, modified or
deleted.
- The user can save an unlimited number of process flows, equipment
types and materials
- A project manager function offers the possibility to save all the user
created data and scenarios (w afer Fab unit, process flow, yields...) and
to reuse them later.
- Two calculation modes: for dedicated fabs and non-dedicated fabs.
- Simulation of up to five simultaneous scenarios allowing the user to run
sensitivity analysis and compare results like yield improvement,
manufacturing location impact on cost, etc.
- MEMS CoST uses an ExcelTM interface for maximum usability. This tool
will enable you to evaluate the cost per wafer for manufacturing using your
own inputs or using the pre-defined parameters
- included with the tool.
- The use of MEMS CoST:
- Estimation of the MEMS margin
- Understanding of the cost structure
- Competitive analysis
- Cost evaluation for different technology options
- Identification of the cost pain points in your process
- Definition of a business model (fabless, fablight, manufacturing ...)
Compare up to 5 different scenarios
- Cost of the wafer with breakdown (depreciation cost, manufacturing cost,
labor cost, yield losses)
- Cost of the wafer by step (DRIE, sacrificial release ...)
- Equipment cost of the wafer by step
- Equipment cost of the wafer by equipment family (etching, deposition,
lithography, bonding...)
- Material cost of the wafer by step (wet chemicals, gases, sputter targets
...)
- Material cost of the wafer by material family
- Cost of the die with breakdown between wafer, test, dicing...
- Cost of the component with breakdown for die cost, packaging cost, final
test cost, yield losses
- Estimation of the manufacturing price of the component according to
published manufacturer financial results
who should buy this tool
This tool is ideal for strategic marketing executives, process managers and
R&D engineers analyzing the economic feasibility of different MEMS
manufacturing approaches. MEMS equipment suppliers can use MEMS CoST to know
the operating cost of their equipment and can compare with their competitors.
It is also of great help for purchasing managers who want to understand their
supplier' s costs.
