摘要：
A fully inverted type SOI-MOSFET has a channel region 18 constructed of a portion that belongs to a top silicon layer 13 and is located just under a gate electrode 15 and a source region 16 and a drain region 17, which belong to the top silicon layer 13 and are located adjacent to this channel region 18. The channel region 18 is inverted throughout the entire thickness during operation. The source region 16 has a source resistance RS, which satisfies a relation that (1/gm)>RS with respect to the mutual conductance gm of the channel region 18 itself. According to this fully inverted type SOI-MOSFET, the effective mutual conductance (Gm) can be increased.
