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.

Abstract: The present disclosure, in some embodiments, relates to a method of forming a micro-electromechanical system (MEMS) package. The method includes forming one or more depressions within a capping substrate. A back-side of a MEMS substrate is bonded to the capping substrate after forming the one or more depressions, so that the one or more depressions define one or more cavities between the capping substrate and the MEMS substrate. A front-side of the MEMS substrate is selectively etched to form one or more trenches extending through the MEMS substrate, and one or more polysilicon vias are formed within the one or more trenches. A conductive bonding structure is formed on the front-side of the MEMS substrate at a location contacting the one or more polysilicon vias. The MEMS substrate is bonded to a CMOS substrate having one or more semiconductor devices by way of the conductive bonding structure.

Abstract: The present disclosure relates to micro-electromechanical system (MEMS) package that uses polysilicon inter-tier connections to provide for a low parasitic capacitance in MEM device signals, and a method of formation. In some embodiments, the MEMS package has a CMOS substrate with one or more semiconductor devices arranged within a semiconductor body. A MEMS substrate having an ambulatory element is connected to the CMOS substrate by a conductive bonding structure. The conductive bonding structure is arranged on a front-side of the MEMS substrate at a location laterally offset from the ambulatory element. One or more polysilicon vias extend through the conductive MEMS substrate to the bonding structure. The one or more polysilicon vias are configured to electrically couple the MEMS substrate to the CMOS substrate. By connecting the MEMS substrate to the CMOS substrate using the polysilicon vias, the parasitic capacitance and form factor of the MEMS package are reduced.
