Abstract:
1. A microelectronic pressure sensor, comprising: a substrate; a MOSFET transistor including: a gate actuator formed from a second non-conductive material that is different from the first material, the gate actuator being formed above the mobile gate, the gate actuator being in contact with the upper surface and sidewalls of the mobile gate, an upper surface of the gate actuator being configured to receive a pressure from a physical object and to move said mobile gate toward the channel in response to the pressure on the upper surface of the gate actuator, the upper surface of the gate actuator being separated from the cavity by the mobile gate, the gate actuator being an elastic material that has a thickness between the upper surface of the mobile gate and the upper surface of the gate actuator, the thickness of the gate actuator being configured to vertically compress in a plurality of locations in response to the pressure, the plurality of locations corresponding to a plurality of locations on the object.
