摘要:
A method of fabricating semiconductor devices with improved critical dimension (CD) uniformity is provided. The methods include forming photoresist patterns on an etching target layer, forming polymer layers on photoresist patterns on an etching target layer by selectively reacting a reactant gas with the photoresist patterns to provide different thicknesses of the polymer layers according to the position of the photoresist patterns, and etching the etching target layer using the photoresist patterns and the polymer layers as an etch mask.
