Abstract
A pressure sensor comprises a polysilicon sensing membrane. The pressure sensor further includes one or more polysilicon electrodes disposed over a silicon substrate. The sensor also includes one or more polysilicon routing layers that electrically connects electrodes of the one or more polysilicon electrodes to one another, wherein the polysilicon sensing membrane deforms responsive to a stimuli and changes a capacitance between the polysilicon sensing membrane and the one or more polysilicon electrodes. The sensor also includes one or more vacuum cavities positioned between the polysilicon sensing membrane and the one or more polysilicon electrodes.
