Abstract: PURPOSE:To reduce the parasitic resistance between a buried well layer and a formed electrode, by arranging an impurity layer whose concentration is higher than that of an element isolation region, between a buried well layer and the surface of a substrate, in a region where well contact is obtained. CONSTITUTION:A field oxide film 2 is formed on a silicon substrate 1. In the case of an N-channel, boron is implanted with energy of 200KeV or larger to obtain ion concentration of 10<12>-10<13>cm-<2>. In the case of a P-channel, phosphorus is implanted with energy of 400KeV or larger to obtain the same concentration. Thereby a buried well layer 3 is formed. A resist layer 7 masking the region except the vicinity of a well contact region and an element isolation region is formed. An intermediate impurity layer 4 is formed on the buried well layer by implanting ions of about 10<12>cm-<2>, with energy lower than or equal to the implantation energy at the time of forming a buried well in the mask. Thereby the resistance of a high resistance layer remaining between a retrograde well layer and the substrate surface can be reduced.

Title: Thermal recording material
Inventor: MOTOSUGI YUKINORI
IPC: B41M5/42
Filed: 1987-07-27
Abstract: PURPOSE:To record a high density sharp image even by minute heat energy, by specifying the surface Beck smoothness of an under coat layer having fine voids provided between a support and a thermal color forming layer. CONSTITUTION:An under coat layer having fine voids is provided between a support and a thermal color forming layer and the surface Beck smoothness of said layer is set to 2000sec or more. This fine void-containing under coat layer is provided, for example, by providing a layer containing a fine hollow foamable plastic filler wherein a low b.p. solvent is contained in a shell composed of a thermoplastic substance on the support and expanding the same by heating. Since a heat insulating property becomes large and the uniform thermal color forming layer having no unevenness is obtained by providing the fine void-containing under coat layer, the heat energy from a thermal head is effectively transmitted to the thermal color forming layer and dynamic color forming sensitivity is enhanced. Further, since the thermal color forming layer is uniform, calender processing thereafter can be performed under low pressure and, since high smoothness is obtained, background whiteness is high and heat resistant preservability is excellent.
