Abstract
A complementary metal oxide semiconductor (CMOS) device integrated with micro-electro-mechanical system (MEMS) components in a MEMS region is disclosed. The MEMS components, for example, are infrared (IR) thermosensors. The MEMS sensors are integrated on the CMOS device heterogeneously. For example, a CMOS wafer with CMOS devices and interconnections as well as partially processed MEMS modules is bonded with a MEMS wafer with MEMS structures, post CMOS compatibility issues are alleviated. Post integration process to complete the devices includes forming contacts for interconnecting the sensors to the CMOS components as well as encapsulating the devices with a cap wafer using wafer-level vacuum packaging.
