MultiMEMS MPW Design Introduction Course At the end of this course you should be able to: Understand the MultiMEMS organisation. Understand the steps involved in MPW production Understand the limitations and the possibilities of the MultiMEMS MPW process Understand the main laboratory processing steps Use the MPW design handbook in design work Have an understanding of the main possibilities and limitations of the SensoNor foundry process Use the MultiMEMS system in product development

Concept & feasibility Test & evaluation Traditional MST development MEMS development has historically been very research oriented. The manufacturing has been done using a project specific process in a research lab Very costly or impossible to transform to volume production Idea Design & modelling Prototyping 6

Concept & feasibility Development using an industrial MST process Test & evaluation Idea Design & modelling Prototyping Established, documented and qualified (repeatable, reliable) processes developed for MEMS products Infrastructure for support from design and development to manufacturing Easy to ramp up to volume production since an established process is used An established process gives confidence in cost prediction Production ramp-up Trial series production Qualification in system 7

Why Multi Project Wafer? Share the cost with other users! Access to industrial manufacturing process in a cost effective way Low-cost for prototyping compared with a custom run Can be used for low volume production Direct transfer to high volume production 8

MPW Services Today several MPW (Multi Project Wafer) services are available from MEMS Foundries. The following MPW services are offered through Europractice: Bulk Micromachining MPW MultiMEMS (SensoNor) MultiMEMS (SensoNor) Surface Micromachining MPW Bosch SOI Micromachining MPW MEMSOI (TRONIC’S Microsystems) MPW for diffractive optical elements CSEM 9
