The present disclosure relates to a microelectromechanical systems (MEMS) package featuring a flat plate having a raised edge around its perimeter serving as an anti-stiction device, and an associated method of formation. A CMOS IC is provided having a dielectric structure surrounding a plurality of conductive interconnect layers disposed over a CMOS substrate. A MEMS IC is bonded to the dielectric structure such that it forms a cavity with a lowered central portion the dielectric structure, and the MEMS IC includes a movable mass that is arranged within the cavity. The CMOS IC includes an anti-stiction plate disposed under the movable mass. The anti-stiction plate is made of a conductive material and has a raised edge surrounding at least a part of a perimeter of a substantially planar upper surface.
