摘要:
A gate trench 13 is formed in a semiconductor substrate 10. The gate trench 13 is provided with a gate electrode 16 formed over a gate insulating film 14. A portion of the gate electrode 16 protrudes from the semiconductor substrate 10, and a sidewall 24 is formed over a side wall portion of the protruding portion. A body trench 25 is formed in alignment with an adjacent gate electrode 16. A cobalt silicide film 28 is formed over a surface of the gate electrode 16 and over a surface of the body trench 25. A plug 34 is formed using an SAC technique.
