摘要:
A monolithic semiconductor device has an insulating layer formed over a first substrate. A second substrate is disposed over the first insulating layer. A power MOSFET with body diode is formed over the second substrate. A Schottky diode is formed over the second substrate in proximity to the MOSFET. An insulation trench is formed within the second substrate between the MOSFET and Schottky diode. The isolation trench surrounds the MOSFET and first Schottky diode. A first electrical connection is formed between a source of the MOSFET and an anode of the Schottky diode. A second electrical connection is formed between a drain of the MOSFET and a cathode of the Schottky diode. The Schottky diode reduces charge build-up within the body diode and reverse recovery time of the first power MOSFET. The power MOSFET and integrated Schottky can be used in power conversion or audio amplifier circuit.
