  • Semiconductor structure for antenna switching circuit
    Patent number: 9041059
    Abstract: A manufacturing method for antenna switching circuit includes the following steps of: providing a GaAs wafer, which includes a capping layer; disposing an isolation layer to the GaAs wafer for forming a device area; and disposing a gate metal on the capping layer within the device area, wherein an interface between the gate metal and the capping layer forms a Schottky contact, and the Schottky contact is parallel connected with an impedance. The present invention also discloses a semiconductor structure for antenna switching circuit.
    Type: Grant
