Abstract

 

The presentation proposes a virtual IDM pattern of fabless designer + semiconductor foundry for MEMS industrialization in China. Based on the pattern, an analog IC foundry compatible MEMS technique, named MIS process, is developed and volume fabricated. With the foundry compatible MIS process implemented from single-side of non-SOI single wafer, various MEMS sensors can be high-yield fabricated that include pressure sensors, accelerometers, TPMS composite sensors, micro flow-meters, infra-red sensors, resonant bio/chemical sensors and microphones. Besides, a liquid-metal refilling TSV technique is developed for low-cost and high-efficiency MEMS packaging. At last, the presentation addresses an intelligent energy-harvesting technique for non-supplied wireless IoT monitoring nodes.
