Abstract: PURPOSE: A method for forming a transistor of a semiconductor device is provided to form a gate insulation layer of a good quality by making a conductive layer pattern formed of a slope type wherein a source/drain region is formed in the conductive layer pattern in forming a transistor of a pin structure. CONSTITUTION: The first insulation layer(12) and the first conductive layer are sequentially formed on a substrate(10). The first conductive layer is patterned to form the first conductive layer pattern wherein the first conductive layer pattern is sloped in a way that the lower part of the first conductive layer pattern is broader than the upper part of the first conductive layer pattern. Ions for controlling a threshold voltage are implanted into the first conductive layer pattern. A gate insulation layer(17) is formed on the resultant structure. A gate electrode(16) is formed on the gate insulation layer. An ion implantation process using the gate electrode as an ion implantation mask is performed to form the first source/drain region. A spacer is formed on the sidewall of the gate electrode. An ion implantation process using the spacer as an ion implantation mask is performed to form the second source/drain region.
