Low cost prototyping and limited volume production are possible with Multi Project Wafer (MPW) services in which devices of different customers are fabricated in a single wafer run. Since multiple customers share the same mask set, the costs of mask making and fabrication are divided.
The microBUILDER project provides access to state-of-the-art MEMS technologies at SensoNor Technologies and TRONICS Microsystems. The MPW processes are fully documented in the microBUILDER design handbook. Customers have the choice to either use the microBUILDER services for designing a device or to design their own component. For this purpose, special training courses are provided.
The MultiMEMS MPW process offers buried conductors and piezoresistors, thin silicon diaphragms, cantilevers and channels as well as glass and silicon cavities in a triple-stack anodic bonded configuration.

Costs for the SensoNor MPW run
The costs are per project and includes the fabrication and the shipping of at least 100 dies for each submitted project. Customers which submit more than two projects for the same MPW run are eligible for discounts. Discounts may also be offered to returning customers.
The TRONICS MPW process provides silicon channels, mixing pillars, heating electrodes and impedance sensing electrodes.
