SEMICONDUCTOR DEVICE HAVING IMPROVED GATE CAPACITANCE AND MANUFACTURING METHOD THEREFOR

摘要

In a semiconductor device for an SRAM having a capacitor formed between a gate electrode of a MOS transistor and an electrically conductive layer provided in the upper layer of the electrode, there is described a semiconductor device in which the gate electrode has a laminated structure consisting of a polycrystalline silicon layer and a refractory metal silicide layer with a polycrystalline silicon layer in the topmost layer thereof.
