Abstract

PURPOSE: To eliminate effects from other parts and reduce parasitic capacity by using as diffusion region forming mask a photoresist film first and a metal film next when enhancement type and depletion type elements are provided in the same semiconductor substrate.
CONSTITUTION: Three thick field oxide films 2 are formed on the surface of p-type Si substrate 1, and thin gate oxide film 4 is coated on the exposed parts between these on substrate 1. Next, resist film 7 having an opening to enhancement type (E-type) element forming region 31 is provided only on the depletion type (D-type) element forming region, and by injecting ions in substrate 1 in region 31 by using this as mask, p-type region 5 is formed. Subsequently, the entire surface is covered with Al layer 8, and film 7, together with layer 8 lying on this, is removed; and only layer 8 lying on region 31 is retained, and by injecting ions in D-type element forming region 32 by using this as mask, n-type region 6 is formed. Next, layer 8, which has become unneeded, is removed, and E-type and D-type elements are provided in the respective regions.
