Title: Mos-type field effect transistor
Inventor: AOYAMA MASASHIGE
IPC: H01L29/417
Filed: 1989-11-17
Abstract: PURPOSE:To reduce the drain leak current and improve the drain withstand voltage in an MOS transistor by providing an inverse conductivity type low concentration impurity layer formed on a substrate in matching relation with a conductive layer and an inverse conductivity type high concentration impurity layer formed in the low concentration impurity layer. CONSTITUTION:An N<-> layer 27 is provided on a substrate 21 in matching relation with a conductive layer 26, and an N<+> layer 29 is formed on the N<-> layer 27. Therefore, at the end part of a field oxide film 22, it can be avoided in self-matching manner that a channel stopper 23, the N<-> layer 27, the N<+> layer 29 are joined. Thus, even if the concentration in the channel stopper 23 is made higher in order to raise the field inversion voltage, the drain leak current of the MOS transistor is not increased and the drain withstand voltage is not deteriorated. Further, because a contact hole H is formed so that it reaches not only the N<+> layer 29 but also the conductive layer 26, a contact region can be made larger as compared to the conventional MOS transistor so that the allowance for mask shift can be made larger.
