摘要:
A semiconductor device includes an isolation layer formed on and/or over a semiconductor substrate to define an isolation layer, a drift area formed in an active area separated by the isolation layer, a pad nitride layer pattern formed in a form of a plate on the drift area, and a gate electrode having step difference between lateral sides thereof due to the pad nitride layer pattern.
