Claim:
1. A method for manufacturing a microelectromechanical systems (MEMS) package, the method comprising: forming a first trench and a second trench in a front side of a device substrate, wherein a first depth of the first trench is greater than a second depth of the second trench; providing a first MEMS device overlying the first trench and a second MEMS device overlying the second trench; forming a recess in a front side of a cap substrate and bonding the front side of the cap substrate to the front side of the device substrate; wherein, when the cap substrate and device substrate are bonded, a first cavity which includes the first trench is formed between the front side of the cap substrate and device substrate and encloses the first MEMS device, and a second cavity which includes the recess and the second trench is formed between the cap substrate and the device substrate and encloses the second MEMS device.
