Title: Mos field-effect transistor
Inventor: FURUKI TSUTOMU
IPC: H01L27/088
Filed: 1988-05-23
Abstract: PURPOSE:To suppress a drop in a snapback voltage by a method wherein, in a MOS field-effect transistor, a high-concentration impurity region of one conductivity type is formed on the surface of a semiconductor substrate near a channel region or a drain region. CONSTITUTION:A MOS field-effect transistor is constituted of a field oxide film 2, a gate oxide film 3, a gate electrode 4, an N-type source region 5 and a drain region 6. During this process, P<+> type diffusion regions 7 which have been formed by introducing a P-type high-concentration impurity are formed on the surface of a semiconductor substrate 1 near a channel region or the region 6 of the transistor. When a high electric field is applied to the region 6, a substrate current flows due to impact ionization caused by a hot electron; a hole component of the substrate current is absorbed by the regions 7. It is possible to suppress a rise in a substrate potential near the region 5 and to prevent a part between the region 5 and the substrate 1 from becoming a forward direction. By this setup, a drop in a snapback voltage can be suppressed.
