摘要：

We propose an improved lateral trench gate MOSFET with a new trench drain contact. The device is predicted to achieve 25V breakdown voltage and a very low on-resistance of 7.8 m Omega .mm(2), which is by 20% lower than that of previously proposed standard lateral trench gate MOSFETs. The proposed trench contact uniformly distributes the electron current in the drift layer, and effectively reduces the device on-resistance. In the present paper, we also show the detailed electrical characteristics of the fabricated standard trench gate LDMOS. The large current turn-off capability of 1.1x10(4) A/cm(2) was achieved by the fabricated device.
