A process for trimming a photoresist layer during the fabrication of a gate electrode in a MOSFET is described. A bilayer stack with a top photoresist layer on a thicker organic underlayer is patternwise exposed with 193 nm or 157 nm radiation to form a feature having a width w1 in the top layer. A pattern transfer through the underlayer is performed with an anisotropic etch based on H2 / N2 and SO2 chemistry. The feature formed in the bilayer stack is trimmed by 10 nm or more to a width w2 by a HBr / O2 / Cl2 plasma etch. The pattern transfer through an underlying gate layer is performed with a third etch based on HBr / O2 / Cl2 chemistry. The underlayer is stripped by an O2 ashing with no damage to the gate electrode. Excellent profile control of the gate electrode is achieved and a larger (w1−w2) is possible than in prior art methods.
