INVENSENSE SHUTTLE
Challenges for MEMS Product Development Fabrication One product - one process increases barrier to entry Find foundry able and willing to bring up new process Development Fighting both design and process simultaneously Need for fast design iterations to keep up with market New start ups need $50M-$70M, 7+ years to profit Production Over 50% of costs are in package and test Establish high yield and quality Establish reliable supply chain to deliver high quality at low cost Growth Extend and expand product base Maintain competitiveness - add more value and lower cost
InvenSense Shuttle Objectives Offer a proven and high volume CMOS-MEMS platform for MEMS fabrication Speed up development cycle and time to commercialization Bring the fabless CMOS scalable production model to MEMS industry
InvenSense Shuttle Payoff Innovators Faster development cycle by focusing on innovative MEMS designs and not fabrication Faster and lower cost development cycles InvenSense Collaborate on new ideas and opportunities Building a closer relationship with innovators Potential royalty revenue Market More innovations in MEMS More standardization in the industry
