Method of fabricating a recess gate type transistor

摘要

A semiconductor device having recess gates and a method for fabricating the same. The semiconductor device includes a semiconductor substrate having inverse triangular recesses formed therein; a gate insulating film having a designated thickness formed on the semiconductor substrate; gate electrodes formed on the gate insulating film so that the gate electrodes fill the inverse triangular recesses and protrude from the surface of the semiconductor substrate; and first and second junction regions formed in the semiconductor substrate and opposed to each other so that the corresponding one of the gate electrodes is interposed therebetween.
