Abstract:
Disclosed are a gate structure in a trench region of a semiconductor device and a method for manufacturing the same. The semiconductor device includes a pair of drift regions formed in a semiconductor substrate; a trench region formed between the pair of drift regions; an oxide layer spacer on sidewalls of the trench region; a gate formed in the trench region; and a source and a drain formed in the pair of the drift regions, respectively.
