Patent JP-H0274076-A (JP)
Title: Mos type transistor
Inventor: HAYASHI HISAO
IPC: H01L27/088
Filed: 1988-09-09
Abstract: PURPOSE:Not only to enable the improvement of a MOS type transistor of this design in breakdown strength and the reduction of a leakage current but also to make it low in resistance to an on-current by a method wherein an insulating film whose dielectric constant is higher than that of a gate insulating film is provided between a second high resistive semiconductor region and a gate electrode. CONSTITUTION:A second high resistive semiconductor region 8 (offset section) is provided between first high resistive semiconductor regions 5 and 6 under a gate electrode 4 and a low resistive semiconductor region 7a of a channel region 7, and an insulating film 9, whose dielectric constant is higher than that of a gate insulating film 3, is provided between the offset section 8 and the gate electrode 4. Therefore, when a transistor is ON, the insulating film 9 of high dielectric constant functions as a parasitic MOS and the offset section 8 changes to the same conductivity type as the source and the drain region, 5 and 6. Therefore, the resistance of the offset section 8 is made to decrease with the rise of a gate voltage, in result, an ON-current is not restricted by the resistance of the offset section 8. When the transistor is OFF, as it is of offset gate structure, the electric field of a P-N<+> junction is not intensified by a gate voltage, so that the transistor is improved in breakdown strength and a leakage current is decreased.
