Filed: 1978-10-19
Abstract: PURPOSE: To reduce the resistance and electrostatic capacitance of a transistor and increase the conversion conductance thereof by intruding a depletion layer region to part of source region by the effect of drain voltage or gate voltage.  
     CONSTITUTION: Drain voltage is applied to a source region 2 where impurity density is lowered in the vicinity of the boundary between the source region 2 and a substrate 1 to thereby intrude a depletion layer extended from the drain region 3 side to the substrate 1 into the region 2 so as to form a potential barrier by the N +  type n junction in the source region 2. Since the source region 2 for implanting carrier to the channel thus becomes high impurity density of the n +  region, there are increased carriers implanted into the channel over the potential barrier. That is, large current density can be obtained.
