Abstract: PURPOSE: A method for fabricating a MOS transistor is provided to secure a tilt angle of a slanting ion implantation under a reduced gate gap. CONSTITUTION: A gate oxide layer(2), a polysilicon layer(3) and a nitride layer(4) are deposited in sequence on a substrate(1), and the nitride layer(4) is then selectively etched to expose a portion of the polysilicon layer(3). An exposed top portion of the polysilicon layer(3) is partially removed, thus forming a stepped top edge. Thereafter, a nitride sidewall(6) is formed on the stepped top edge of the polysilicon layer(3), and the remaining exposed portion of the polysilicon layer(3) and the underlying gate oxide layer(2) are removed to expose the substrate(1) through the nitride layer(4) and the nitride sidewall(6). Then, a lightly doped source and drain is formed in the exposed substrate(1) by a slanting ion implantation, and a sidewall spacer is formed on a side of a gate. Since a side of the nitride layer(4) is removed on the stepped top edge of the polysilicon layer(3), a distance(a) between the adjacent gates is greater than an actual gate gap. Therefore, a tilt angle(theta) of the slanting ion implantation is secured.
