A High Voltage (100 V) Lateral Trench Power MOSFET with Low Specific-on-resistance
Conventional laterla trench-based components, such as trench lateral transistors, typically have a substantial undesirable capacitance related to the overlap of gate and drain electrodes in the same trench. Particularly, many trench-type lateral transistors are fabricated with the gate and the drain formed in the same trench, typically separated by an oxide layer. The overlap of the gate and drain regions results in a parasitic gate-to-drain capacitance, which can damage frequency response.
