Abstract:
Provided is a method of fabricating a semiconductor device. The method includes providing a substrate, forming a photo acid generator (PAG) layer on the substrate, exposing the PAG layer to radiation, and forming a photoresist layer on the exposed PAG layer. The exposed PAG layer generates an acid. The acid decomposes a portion of the formed photoresist layer. In one embodiment, the PAG layer includes organic BARC. The decomposed portion of the photoresist layer may be used as a masking element.
