Abstract: The present disclosure relates to a MEMs package having a heating element configured to adjust a pressure within a hermetically sealed chamber by inducing out-gassing of into the chamber, and an associated method. In some embodiments, the MEMs package has a CMOS substrate having one or more semiconductor devices arranged within a semiconductor body. A MEMs structure is connected to the CMOS substrate and has a micro-electromechanical (MEMs) device. The CMOS substrate and the MEMs structure form a hermetically sealed chamber abutting the MEMs device. A heating element is electrically coupled to the one or more semiconductor devices and is separated from the hermetically sealed chamber by an out-gassing layer arranged along an interior surface of the hermetically sealed chamber. By operating the heating element to cause the out-gassing layer to release a gas, the pressure of the hermetically sealed chamber can be adjusted after it is formed.
