Abstract: PURPOSE:To narrow a width of an active region by restraining transverse diffusion of a channel stopper region below an element isolation region and to reduce a resistance of a substrate by providing a inversely inclined well below the active region. CONSTITUTION:A field insulating film 2 and a photoresist film 3 are laminated on a surface of a P-type semiconductor substrate 1. A semiconductor substrate in an active region 4 is exposed through photoetching method. Then, boron ions are implanted at an accelerating voltage which maximizes an impurity distribution near a bottom of the field insulating film 2. Boron ions are implanted deep also into the active region 4. After the photoresist film 3 is removed, heat treatment is carried out to activate implanted boron ions. A channel stopper region 5 is formed below the field insulating film 2, and a well region 6 whose impurity concentration distribution is inversely inclined is formed below the active region 4 simultaneously. According to this method, transverse diffusion can be restrained because heat treatment is not applied to the channel stopper region 5 for many hours.
