ABSTRACT:
Semiconductor devices and methods of manufacturing the same are disclosed. A disclosed semiconductor device comprises a semiconductor substrate; a gate formed on the semiconductor substrate; a gate oxide layer interposed between the semiconductor substrate and the gate; and source and drain regions formed within the substrate at opposite sides of the gate. The gate oxide layer has a first region with a first thickness and a second region with a second thickness. The second thickness is thicker than the first thickness.
