Abstract:
The present disclosure relates to a MEMS package with a rough metal anti-stiction layer, to improve stiction characteristics, and an associated method of formation. In some embodiments, the MEMS package includes a MEMS IC bonded to a CMOS IC. The CMOS IC has a CMOS substrate and an interconnect structure disposed over the CMOS substrate. The interconnect structure includes a plurality of metal layers disposed within a plurality of dielectric layers. The MEMS IC is bonded to the CMOS IC, enclosing a cavity between the MEMS IC and the CMOS IC and a moveable mass arranged in the cavity. The MEMS package further includes an anti-stiction layer disposed under the moveable mass. The anti-stiction layer is made of metal and has a rough top surface.

Claim (Index 5):
The MEMS package of  claim 4 , wherein an uppermost region of the rough top surface is spaced apart from a lower surface of the moveable mass by a first vertical distance, and an uppermost region of the smooth top surface is spaced apart from the lower surface of the moveable mass by a second vertical distance, the second vertical distance being greater than the first vertical distance.
