Title: Electrostatic protective circuit for mosic
Inventor: INOUE KAZUAKI
IPC: H01L27/06
Filed: 1982-06-14
Abstract: PURPOSE:To obtain the electrostatic protective circuit, having an excellent area efficiency, which will be used effectively by a method wherein a resistor consisting of a shallowly formed diffusion layer is provided. CONSTITUTION:When static electricity is generated on a pad region, a resistor 5 is formed using a P type drive-in stopper 5 for the purpose of protecting the gate oxide film located below a gate electrode 6. The characteristics of said drive-in stopper are that the depth of the region, whereon diffusion will be formed is shallow and density in thin when compared with those of the other diffusion regions, and that the characteristics are quite effectively used when taking measure for static electricity. To be more precise, the sheet resistance of a P<+> diffusion region is approximately 30OMEGA, whereas the convensional pattern requires a substantial area for the same resistance value as above. Also, as its depth is shallow and density is thin, a pinch-off is easily generated when a high voltage such as static electricity is applied, thereby allowing to give rise to a high resistance. This protective circuit is optimum from the view point of gate oxide film protection.
