Abstract

See full text

Embodiments of the present disclosure include MEMS devices and methods for forming MEMS devices. An embodiment is a method for forming a microelectromechanical system (MEMS) device, the method including forming a MEMS wafer having a first cavity, the first cavity having a first pressure, and bonding a carrier wafer to a first side of the MEMS wafer, the bonding forming a second cavity, the second cavity having a second pressure, the second pressure being greater than the first pressure. The method further includes bonding a cap wafer to a second side of the MEMS wafer, the second side being opposite the first side, the bonding forming a third cavity, the third cavity having a third pressure, the third pressure being greater than the first pressure and less than the second pressure.
