Abstract
PURPOSE:To provide conduction between a substrate or well and interconnections, by implanting the same dopant as that of the substrate or well, into a diffused layer of an unused source electrode to which a diffused layer pattern for specific code data has not yet been added. CONSTITUTION:A prepared basic pattern has a source line 4 connected to a source electrode common to all the codes, a diffused layer 5 corresponding to a source of a MOS transistor cell connected to the source electrode, a gate polysilicon 1, an output line 3 and a contact 2 for connecting the output line 3 with the drain electrode of the MOS transistor. Pattern of a part of the diffused layer where the MOS transistor is present, said part being variable according to various codes, is added to the basic pattern so that the code is inputted. An effect equivalent to that of substrate contact can be obtained, by adding a doped layer 6 doped with the same dopant as the substrate to a unused diffused layer 7 by means of the additional pattern.
