Title: Semiconductor device
Inventor: SHIRATA RIICHIRO
IPC: H01L29/78
Filed: 1986-08-19
Abstract: PURPOSE:To prevent implanted ions from reaching a substrate due to channeling in a gate electrode when ions are implanted with the gate electrode as a mask and to prevent deterioration in characteristics of a MOSFET, by setting the size of the diameter of a crystal grain in the polycrystalline gate electrode smaller than the thickness of a gate film. CONSTITUTION:Polycrystalline silicon 3 and 1, in which N-type impurities (arsenic or phosphorus) are doped by a CVD method, is evaporated on a gate oxide film on a P-type semiconductor substrate 1. Said part is utilized as a gate electrode. Since the N-type impurities are doped, the resistance is made low. It is not necessary to diffuse phosphorus into the polycrystalline silicon. Therefore, the diameter of a crystal grain is small. The gate material is etched with resist as a mask, and a gate electrode 3 is formed. For example, a gate/drain diffused layer 4 is formed by implanting ions with the gate electrode as a mask. Since the diameter of the crystal grain of the polycrystalline silicon in the gate electrode is small, the ions implanted in the gate electrode do not cause channeling but are stopped in a halfway. Therefore, the ions do not reach the substrate.
