Abstract: PURPOSE:To enable the production of the device with high throughput without depending on the performance of an ion implanting machine, by a method wherein a silicide layer is formed on the surface of silicon and thereafter ion implantation of impurities is executed using as a mask a thin film of metal which is a component of said silicide, so as to form a junction which is shallow and little impaired. CONSTITUTION:A thin silicide layer 4 (of about 50nm) is made to grow on a silicon substrate 1, and an unreacted high-melting metal 3 is removed selective ly. Heat treatment of high temperature (1,000 deg.C or above) is conducted to re move as much defect occurring at this time as possible. After the high-melting metal film 3 constituting the silicide is deposited as a protection film used on the occasion of implantation of impurities (B<+> in particular), ion implantation of the impurities is executed with such an energy as enables the maintenance of high throughput. Since the high-melting metal film 3 in the upper layer used as the protection film can be removed selectively in relation to the silicide layer positioned below, heat treatment is conducted, in this state, to activate the impurities, and then the high-melting metal film 3 is removed.
