Abstract
An anti-reflective coating layer for the manufacturing of semiconductor devices is disclosed. In one example, a partial semiconductor device includes a substrate; a bottom anti-reflective coating (BARC) layer over the substrate, and the BARC layer is transformed from being hydrophobic to being hydrophilic during a lithography process; and a photoresist layer over the BARC layer.
