Abstract
PURPOSE: To make the width of a gate region equal to that of a gate electrode by masking a part which becomes a source or drain region with a gate electrode component substance when forming the channel stopper region of a MOS transistor.
CONSTITUTION: On Si substrate 31, SiO2 films 32 are formed to form an insulating separation region between elements. Next, a SiO2 film is formed on substrate 31 and polycrystal Si containing phosphorus is adhered onto it and removed selectively by being photoetched to form gate insulation film 33 and gate electrode 34, On it SiO2 film 35 is formed, on which polycrystal Si film 36 is adhered. Next, polycrystal Si is selectively removed only in the width direction by being photoetched and with SiO2 film 35 left, self-matching type channel stopper region 38 is formed in the width direction of the MOS transistor. Then, polycrystal Si 36 is removed selectively by being photoetched to form gate electrode 40 and gate insulation film 41. Further, this photoresist 39 is used to form self-matching type source region 42 in the length direction of the transistor. In this way,the size for one element can be reduced.
