Abstract:
Various embodiments of the present disclosure are directed towards a method for manufacturing an integrated chip, the method comprises forming an interconnect structure over a semiconductor substrate. An upper dielectric layer is formed over the interconnect structure. An outgas layer is formed within the upper dielectric layer. The outgas layer comprises a first material that is amorphous. A microelectromechanical systems (MEMS) substrate is formed over the interconnect structure. The MEMS substrate comprises a moveable structure directly over the outgas layer.
