Patent ID: 8399333

Claim:
A method to simultaneously form a micro-electromechanical systems (MEMS) switch and a MEMS fixed capacitor comprising: providing a substrate; forming a first insulator layer over the substrate; forming a contact bump structure of a fixed contact of the MEMS switch from a first structural metallization layer, wherein the first structural metallization layer is over the first insulator layer; forming an actuator of the MEMS switch, a first capacitive plate of the MEMS fixed capacitor, and a contact portion of the fixed contact of the MEMS switch with a first metallization layer, wherein the first metallization layer is over a portion of the first insulator layer and the contact bump structure; forming an actuator insulator of the MEMS switch and a fixed dielectric layer of the MEMS fixed capacitor with a second insulator layer, wherein the second insulator layer is over a portion of the first metallization layer and a portion of the first insulator layer; forming a first portion of a movable contact of the MEMS switch and a first portion of a second capacitive plate of the MEMS fixed capacitor with a second metallization layer, wherein the second metallization layer is over a portion of the first metallization layer, the actuator insulator, and the fixed contact of the MEMS switch, and wherein the second metallization layer is over a the fixed dielectric layer of the MEMS fixed capacitor; forming a second portion of the movable contact of the MEMS switch and a second portion of the second capacitive plate of the MEMS fixed capacitor with a cantilever structure layer, wherein the cantilever structure layer is over portion of the second metallization layer.
