Disclosed are a semiconductor device and a method of manufacturing the same. The semiconductor device includes a substrate formed therein with a first conductive type well, and an LDMOS device formed on the substrate. The LDMOS device includes a gate electrode, gate oxides formed below the gate electrode, a source region formed in the substrate at one side of the gate electrode, and a drain region formed in the substrate at an opposite side of the gate electrode. The gate oxide includes first and second gate oxides disposed side-by-side and having thicknesses different from each other. |
