Abstract
PURPOSE:To restrain leak current, and improve subthreshold characteristics, by making a part sandwitched by a source region and a drain region of a semiconductor substrate surface just under a gate electrode, and the source.drain region not brought into contact with a field oxide film side-wall. CONSTITUTION:In a P-well 4 defined by a field oxide film 3, an N-channel MOS transistor having a source region 5'a and a drain region 5'b is included. The surface part of a P-type Si substrate just under the source region 5'a, the drain region 5'b and a gate electrode 7, i.e., a part on a P-type well sandwitched by the drain 5'b and the source region 5'a is separated 0.5mum away from the field oxide film. Thereby, the leak current between the source region 5'a and the drain region 5'b is avoided, and subthreshold characteristics are improved.
