Abstract

The invention provides a transverse double-diffused metal oxide semiconductor device and an electronic device. The semiconductor device comprises a substrate; and a source region and a drain region, and the source region and the drain region are located in the substrate, wherein a source and a drain are formed on the surface of the substrate on the source region and the drain region, respectively,and a schottky diode is formed between the source and the drain. The drift extension in the off state is depleted by the body region and the device operates as a conventional LDMOS. When the device is switched on or switched off, the schottky diode is switched on or switched off more quickly and is turned on earlier to improve high frequency performance.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a lateral double-diffused metal oxide semiconductor device and an electronic device having the same. Background technique [0002] With the continuous development of semiconductor technology, lateral double-diffused metal-oxide-semiconductor field-effect transistor (LDMOS) devices are widely used in power integrated circuits because of their good short-channel characteristics. LDMOS devices are well suited for applications in RF (Radio Frequency) base stations and power MOSFET (Metal Oxide Semiconductor Field Effect Transistor) conversion. In the application of RF technology, because LDMOS has high power performance, high gain, excellent linearity (linearity) and low manufacturing cost, LDMOS devices are mainly used in base station circuits. In the application of power MOSFETs, such as in DC-CD converters, LDMOS devices have excellent conversion performance, and compared ...
