Zusammenfassung:A method for manufacturing a laterally diffused metal oxide semiconductor device and a semiconductor device are provided. A body region is formed before forming a gate dielectric layer and a gate conductor, thereby reducing a channel length of the semiconductor device, thus reducing the on-resistance. In addition, a drift region serves as both a region withstanding a high voltage and a diffusion suppression region for suppressing lateral diffusion of the body region, thereby further reducing the channel length of the semiconductor device, thus manufacturing a short-channel semiconductor device.
