ABSTRACT:
A method for patterning a low dielectric insulating layer of a semiconductor device improves adhesion between a photoresist and the low dielectric (Low-K) insulating layer by removing at least one hydroxyl group from a surface of the Low-K insulating layer with a beam. Reliability of the device is thereby improved. The method includes forming a Low-K insulating layer on a semiconductor substrate, irradiating the Low-K insulating layer with a beam to make the Low-K insulating layer hydrophobic, forming a photoresist pattern on the Low-K insulating layer, and ashing the photoresist pattern.
