  • Patent number: 9884758
    Abstract: The present disclosure relates to a MEMS package having an outgassing element configured to adjust a pressure within a hermetically sealed cavity by inducing outgassing of into the cavity, and an associated method. In some embodiments, the method is performed by forming an outgassing element within a passivation layer over a CMOS substrate and forming an outgassing resistive layer to cover the outgassing element. The outgassing resistive layer is removed from over the outgassing element, and the MEMS substrate is bonded to a front side of the CMOS substrate to enclose a first MEMS device within a first cavity and a second MEMS device within a second cavity. After removing the outgassing resistive layer, the outgassing element releases a gas into the second cavity to increase a second pressure of the second cavity to be greater than a first pressure of the first cavity.

  • Publication number: 20170107100
    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.

  • Publication number: 20170107097
    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.
