    • PROBLEM TO BE SOLVED: To provide a semiconductor device equipped with a LDMOS which secures ESD resistance.
      SOLUTION: A doped Poly-Si 6 is arranged in a trench 4 through an insulating layer 5, this doped Poly-Si 6 is made to be connected with a gate electrode 12. By such a structure, the gate electrode 12 is made to have a gate voltage potential and a channel region is made to be on, which enables a current to flow easily between an n
      + -type drain region 10 and an n
      + -type source region 9. LDMOS is thereby prevented from being thermally broken by a surge current. By adjusting the impurity concentration of the doped Poly-Si 6 embedded in the trench 4, and by changing this resistance, the ESD resistance is controlled, and thus the ESD resistance is secured.
