Abstract
A method for fabricating a MOSFET includes a step of forming an isolation layer on an isolation region of a substrate, to thereby define an active region ion implanting As and P into the active region, and a step of forming a gate on the active region. An ion implanting step of low-concentration impurity using the gate as a mask is performed to form a low-concentration ion-implanted region in a predetermined portion of the substrate which is placed on the right and left sides of the gate. A sidewall spacer on the sides of the gate is formed, and thereafter, and ion implanting high-concentration impurity into the substrate is performed.
