Abstract: <P>PROBLEM TO BE SOLVED: To reduce gate capacitance, to suppress the occurrence of and to improve a gate withstand voltage in a trench gate type transistor.  <P>SOLUTION: A trench 14 is formed on an N-type semiconductor layer 12. In the trench 14, a uniformly thick silicon oxide film 15A rounded at corner sections 12A and 12B is formed at the bottom section and its vicinity. Silicon oxide films 15B which are thinner than the silicon oxide film 15A and are rounded at corner sections 12C and 12D are formed above side walls of the trench 14. Furthermore, a gate electrode 18 is formed to extend from the inside of the trench 14 to the outside. The gate capacitance is reduced by the thick silicon oxide film 15A, and excellent transistor characteristics are ensured by the silicon oxide films 15B above the silicon oxide film 15A. The rounding of the corner sections 12A and 12B suppresses the occurrence of crystal defects and improves the gate withstand voltage by dispersing the gate electric field.  <P>COPYRIGHT: (C)2009,JPO&INPIT
