Abstract
A device comprising a micro-electro-mechanical system (MEMS) substrate with protrusions of different heights that has been integrated with a complementary metal-oxide-semiconductor (CMOS) substrate is presented herein. The MEMS substrate comprises defined protrusions of respective distinct heights from a surface of the MEMS substrate, and the MEMS substrate is bonded to the CMOS substrate. In an aspect, the defined protrusions can be formed from the MEMS substrate. In another aspect, the defined protrusions can be deposited on, or attached to, the MEMS substrate. In yet another aspect, the MEMS substrate comprises monocrystalline silicon and/or polysilicon. In yet even another aspect, the defined protrusions comprise respective electrodes of sensors of the device.
