发明名称 Etch stop control for MEMS device formation
摘要 A microelectromechanical device is formed in a silicon semiconductor substrate. A metalization layer is formed on a glass wafer. A metal cap layer is then formed on the metalization layer, such that combined layers have a small surface work function that is less than approximately 5.17 eV. The semiconductor substrate is anodically bonded to the glass wafer, and then etched to remove silicon from the structures without significant excess etching of the microelectromechanical device, thus maintaining good control over critical dimensions of the microelectromechanical device.
