Abstract
PURPOSE:To prevent the increase of a threshold voltage and an irregularity thereof in a MOS semiconductor device by forming the same conducting type high impurity density buried layer as the substrate at the deep position in either one side of source or drain region side in a channel region. CONSTITUTION:An n<+>-type source region 21 and a drain region 22 are formed on a p-type silicon substrate 11, a polycrystalline silicon oxide film 18 as the gate electrode is formed through a silicon oxide film 17 as a gate insulating film on the channel region between the regions 21 and 22, and the same conducting type high impurity density p<+>-type buried layer 10 as the substrate 11 is formed at deep position at the drain region 22 side in the channel region. Further, a field oxide film 16 and a p<+>-type channel stopper are formed thereon.
