Filed: 1984-12-28
Abstract: PURPOSE:To enable good direct contact to be obtained by a method wherein the titled device is so constructed that the impurity concentration of the source- drain regions of a transistor constituting a memory cell is lower than that of the source-drain regions of a peripheral circuit transistor. CONSTITUTION:The generation of an interfacial barrier made of a spontaneous oxide film can be prevented by forming N<-> type impurity regions 30 having an impurity concentration of approx. 1X10<18>cm<-3> at the contact part of the bit line 37 of a dynamic memory and the substrate Si 21. Thereby, much better ohmic contact can be obtained even without adapting conventional methods of high-temperature phosphorus diffusion and heat treatment for barrier breakdown or high-acceleration-high dosage ion implantation for barrier breakdown by ion mixing. Besides, the junction of a P<+> type impurity region effective in soft error prevention is not the conventional P<+>N<+> junction but the P<+>N<-> junction; therefore, the increase of the generation-recombination center can be inhibited.
