IPC: H01L29/78
Filed: 1990-03-28
Abstract: PURPOSE:To simplify the process by finishing it up with one time ion implantation by a method wherein a gate polysilicon film is formed on a gate insulating film formed on a semiconductor substrate and after accelerating and discharging molecular ions in different conductivity type from that of the impurities of the substrate from an ion source, the ions are further subjected to rear-stage acceleration and then implanted in the whole surface of the semiconductor substrate simultaneously to form source.drain and channel regions. CONSTITUTION:A gate polysilicon film 3 is formed on a gate oxide film 2 formed on an n-type silicon wafer 1 and then boron fluoride ions are implanted in the whole surface using a rear-stage acceleration type ion implantation device. At this time, the projection range of the ions to a substrate becomes shorter than that of implanted ions so that the impurities in high concentration may be shallowly distributed as source.drain region 5, 6 but not to reach a channel region 4 due to the existence of the gate polysilicon film 3. On the other hand, molecular ions are isolated to produce the unit ions in the longer projection range capable of penetrating the gate polysilicon film 3 and forming the channel layer 4 beneath the film 3 as a small layer in the low impuriy concentration and the same conductivity type as that of the source.-drain region 5, 6.
