High voltage semiconductor device and method of manufacturing the same |
摘要 |
A high voltage semiconductor device includes a well region of a first conductive type formed at a surface portion of a substrate, a gate electrode disposed on the well region, a source region formed at a surface portion of the well region adjacent to the gate electrode, a drain region formed at a surface portion of the well region adjacent to the gate electrode, and a drift region of a second conductive type disposed under the drain region. |
