    摘要: A method for etching an ultra thin film is provided which includes providing a substrate having the ultra thin film formed thereon, patterning a photosensitive layer formed over the ultra thin film, etching the ultra thin film using the patterned photosensitive layer, and removing the patterned photosensitive layer. The etching process includes utilizing an etch material with a diffusion resistant carrier such that the etch material is prevented from diffusing to a region underneath the photosensitive layer and removing portions of the ultra thin film underneath the photosensitive layer.

    摘要: 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.
