Abstract: PURPOSE:To obtain the titled device with the countermeasure against an effective parasitic bi-polar circuit without producing problems in pattern layout, the dispersion of the threshold values of an MOS transistor, and the decrease of the yield by a method wherein a metallic layer or a high concentration impurity diffused layer is formed on the wafer surface on the side wherein an element is not formed. CONSTITUTION:After a P-well 2 and the MOS transistor are formed in the main surface of an N type substrate 1, a low resistant layer 3 is formed by vapor-depositing Au on the back surface of said substrate 1. Thereafter, the wafer is diced into chips, which are then made as products through the normal mounting process. Using a normal semiconductor substrate, a required MOS transistor circuit is formed, and the formation of a protection film to the main surface of the wafer, etc. is finished. Afterwards, a low resistant layer is formed on the back surface of the wafer by a process without heat treatment such as vapor deposition. The metallic component is not always Au. In the process of forming the MOS transistor in the substrate, a high concentration impurity is introduced into the back surface of the substrate e.g. by ion implantation, and this high concentration impurity layer can be made as the low resistant layer.
