摘要
Processes for integrating complementary metal-oxide-semiconductor (CMOS) devices with microelectromechanical systems (MEMS) devices are provided. In some embodiments, the MEMS devices are formed on a sacrificial substrate or wafer, the sacrificial substrate or wafer is bonded to a CMOS die or wafer, and the sacrificial substrate or wafer is removed. In other embodiments, the MEMS devices are formed over a sacrificial region of a CMOS die or wafer and the sacrificial region is subsequently removed. Integrated circuit (ICs) resulting from the processes are also provided.
