Abstract: PURPOSE:To fabricate a mechanically reinforced T type gate structure by providing a T type gate electrode so as to have its intermediate portion having a wider horizontal formation width than a predetermined formation width between a horizontal portion and a vertical portion. CONSTITUTION:An active region 2 is formed on a semiconductor substrate 1, and a T-shaped cross section T type gate electrode 3 is provided on a recess 4 which is formed on part of a surface of the active region 2. The T type gate electrode 3 comprises an upper portion 3A, a lower portion 3B, and a junction portion 5 which joins the upper portion 3A and the lower portion 3B. A formation width Ld of the junction portion 5 is formed to be sufficiently larger than a gate length Lg which is a width of the lower portion 3B. Hereby, junction strength between the upper portion 3A and the lower portion 3B is reinforced so that even if any stress is excerted on the T type gate electrode 3 owing to temperature rise during current introduction, the gate electrode is not destroyed in the vicinity of the junction portion 5 for high mechanical strength.
