Title: Manufacture of mos semiconductor device
Inventor: TANAKA HIROYUKI
IPC: H01L29/78
Filed: 1987-10-16
Abstract: PURPOSE:To decrease the quantity of movable ions, and to prevent both the variation of V1 and the lowering of gm by employing a specific process in which phosphorus ions are implanted into a polycrystalline silicon layer before or after the introduction of P-type impurities to the polycrystalline silicon layer. CONSTITUTION:A gate oxide film 13 is first formed on an N-type silicon substrate 11, and a polycrystalline silicon layer 14 is then deposited on the surface of the gate oxide film 13. Subsequently, boron or BF2 ions (of P type) are implanted into the polycrystalline silicon layer 14 to introduce P-type impurities into the polycrystalline silicon layer 14. Next, phosphorus ions as N-type impurity ions are implanted into the polycrystalline silicon layer 14. As a result, since the polycrystalline silicon layer 14 contains P-type phosphorus ions, this layer 14 has the gettering effects by which Na ions intruding from outside are gettered so that the Na ions do not reach the gate oxide film 13. Accordingly, both the variation of VT and the lowering of gm are effectively prevented.
