摘要： PURPOSE:To improve the characteristics of a semiconductor integrated circuit device having a MISFET and to improve the yield of the device. CONSTITUTION:Oxidation-resistant films 4 and 6 are respectively provided on the upper part and sidewalls of a gate electrode of a MISFET Q and oxide films 5 and 8 are respectively provided on the upper part and sidewalls of the gate electrode 3 via these films 4 and 6. Accordingly, as the path of oxygen to intrude through the films 5 and 8 on the upper part and sidewalls of the gate electrode 3 is blocked by the films 4 and 6, oxidation of an oxidizable conductive film constituting the electrode 3 is less, and crystal defects in the main surface part of a semiconductor substrate 1, which is caused by the volume expansion of the substrate, can be reduced.

摘要： PURPOSE:To obtain a solid-state image pickup device with little random noise by a method wherein a portion under a diffused layer contacting with a vertical signal line is constructed by a four-layer structure composed of n -p -p -p well deposit layers. CONSTITUTION:A p layer 12 is provided between an n diffused layer 4 and a p layer 6. Regarding this p 12, it can be said that when an impurity, e.g. phosphorus, opposite to the one of the p layer 6 is diffused into this layer, an n type impurity is put into a p type impurity layer and consequently the density of the p layer 6 is reduced equivalently. Assuming that the impurity density of the p layer 6 is Np , the capacity Cv of a vertical signal line 11 is reduced by the reduction of the density of the p layer 6, since Cvproportional (Np ) . By this constitution, random noise can be lessened, and thus an image having a high S/N ratio and a very high quality can be obtained.
