Patent ID: 7956429

Claim:
A semiconductor die comprising: a substrate; a first micro-electromechanical system (MEMS) device comprising: an actuator formed by a first metallization layer over the substrate; a first movable member formed by a second metallization layer that is suspended over the actuator, and wherein the first movable member is configured to move toward the actuator upon actuation of the first MEMS device; and a first insulator layer between the actuator and the first movable member and positioned to prevent the first movable member from contacting the actuator upon actuation of the first MEMS device; a second micro-electromechanical system (MEMS) device comprising: a fixed capacitive plate formed by the first metallization layer over the substrate; a second movable member formed by the second metallization layer that is suspended over the fixed capacitive plate, and wherein the second moveable member is configured to move toward the fixed capacitive plate upon actuation of the second MEMS device; the first insulator layer between the fixed capacitive plate and the second movable member and positioned to prevent the second movable member from contacting the fixed capacitive plate upon actuation of the second MEMS device.
