Abstract
Provided is a semiconductor device. The device includes a substrate having a photo acid generator (PAG) layer on the substrate. The PAG layer is exposed to radiation. A photoresist layer is formed 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.
