摘要:
In order that a top surface of a gate electrode does not have sharp portions, ends of the top surface of the gate electrode are rounded before refractory metal is deposited for silicidation. This reduces intensive application of film stresses which are generated in heat treatment, enabling formation of a silicide layer with a uniform, sufficient thickness.
