Title: Mos type semiconductor device
Inventor: ARITOME SEIICHI
IPC: H01L27/115
Filed: 1989-02-22
Abstract: PURPOSE:To increase the density of a MOS type semiconductor device without lowering element isolation capacity and breakdown strength by providing a recessed section for ensuring a specified distance from an edge to a section of the element isolation region of a gate electrode wiring pattern. CONSTITUTION:A recessed section 15 is shaped onto an element isolation region in the pattern of a gate electrode 111, thus ensuring a distance A from the edge of a p<+> type layer 13 for preventing inversion to the gate electrode 111 at a predetermined value. A distance B from an n<+> type 9 to a p<+> type layer 13 is also secured at a fixed value, thus arranging a bit-line contact section 14 to a section nearer to the gate electrode than conventional devices. Consequently, the density of an E<2>PROM array can be made higher than conventional devices without lowering element isolation capacity and breakdown strength. The device is applied to a NAND cell type E<2>PROM at that time, but the device can be applied to all MOS type integrated circuits having structure in which other type E<2>PROM, EPROM and MOS transistors are disposed adjacently while the gate electrode is used in common similarly.
