Abstract: A method of forming a resist pattern in a semiconductor device layer includes forming a buffer layer on a semiconductor device layer and forming a resist layer on the buffer layer. A decomposing agent is released into a portion of the buffer layer by a portion of the resist layer whereupon the portion of the buffer layer and the portion of the resist layer are removed to form a process window substantially free of resist residue that can be subsequently exploited for etching of the semiconductor device layer.

Abstract: An ESD-resistant photomask and method of preventing mask ESD damage is disclosed. The ESD-resistant photomask includes a mask substrate, a pattern-forming material provided on the substrate, a circuit pattern defined by exposure regions etched in the pattern-forming material, and positive or negative ions implanted into the mask substrate throughout ion implantation regions. The ions in the ion implantation regions dissipate electrostatic charges on the mask, thus preventing the buildup of electrostatic charges which could otherwise attract image-distorting particles to the mask or damage the mask.

Abstract: A method of performing immersion lithography on a semiconductor substrate includes providing a layer of resist onto a surface of the semiconductor substrate and exposing the resist layer using an immersion lithography exposure system. The immersion lithography exposure system utilizes a fluid during exposure and may be capable of removing some, but not all, of the fluid after exposure. After exposure, a treatment process is used to remove the remaining portion of fluid from the resist layer. After treatment, a post-exposure bake and a development step are used.

Abstract: A method for forming a semiconductor device includes forming a photoresist layer over a substrate and patterning the photoresist layer to form photoresist portions. A second layer is formed over the substrate in areas not covered by the photoresist portions and the photoresist portions are removed. After removing the photoresist portions, the second layer is used to modify the substrate to create at least a portion of the semiconductor device.

Abstract: In a photolithography process, a photoresist layer is formed on a substrate. A photomask is aligned over the substrate to transfer pattern images defined in the photomask on the substrate. The photomask includes first and second patterns of different light transmission rates, and a dummy pattern surrounding the second pattern having a light transmission rate lower than that of the first pattern. The substrate is exposed to a light radiation through the photomask. The photoresist layer then is developed to form the pattern images. The dummy pattern is dimensionally configured to allow light transmission, but in a substantially amount so that the dummy pattern is not imaged during exposure.
