Abstract
A high voltage MOS transistor comprising a substrate, a well, a gate insulating layer, a gate, two drift regions, a channel region, a source/drain region and an insulator is provided. The well is disposed in the substrate. The gate insulating layer is formed over the substrate. The gate is disposed over the gate insulating layer. The drift regions are located in the well beside the gate, wherein the gate has a width not more than that of the drift regions. The channel region is located between the drift regions, wherein the channel region has a width larger that of the drift regions. The source/drain regions are formed in the two drift regions respectively. The insulator is formed in the two drift regions and between the channel region and the source/drain regions. The insulator and the source/drain regions are surrounded by the two drift regions.
