Abstract:
A photoresist material having a polymer that turns soluble to a base solution in response to reaction with acid. The material includes a photo-acid generator (PAG) that decomposes to form acid in response to radiation energy and a quencher capable of neutralizing acid and having a reduced mobility. The photoresist material can thereby prevent water mark defects from immersion lithography.
Abstract:
A method for fabricating an integrated circuit device is disclosed. The method includes providing a substrate; forming a first material layer over the substrate; forming a second material layer over the first material layer, wherein the second material layer comprises a photodegradable base material; and exposing at least a portion of the second material layer.
Abstract:
The present disclosure provides a method for manufacturing a semiconductor device. The method includes coating a photoresist on a substrate. The photoresist is exposed to radiation. The radiation exposed photoresist is baked. The radiation exposed and baked photoresist is developed to create an image pattern. The image pattern is treated with a treating material. An ion implantation process is performed to the substrate and the treated image pattern. The image pattern is stripped from the substrate. A carbon atom ratio of the treating material is less than a carbon atom ratio of the photoresist.
Abstract:
A method of lithography patterning includes forming a first material layer on a substrate; forming a first patterned resist layer including at least one opening therein on the first material layer; forming a second material layer on the first patterned resist layer and the first material layer; forming a second patterned resist layer including at least one opening therein on the second material layer; and etching the first and second material layers uncovered by the first and second patterned resist layers.
Abstract:
A method comprises forming a photoresist on a substrate, rinsing the photoresist using a rinse liquid agitated with at least one megasonic source, exposing the photoresist to radiation while immersed in a liquid, and developing the photoresist.
Abstract:
An optical proximity correction photomask comprises a transparent substrate, a main feature having a first transmitivity disposed on the transparent substrate and at least one assist feature having a second transmitivity disposed to each side of the main feature and on the transparent substrate, wherein the first transmitivity is not equal to the second transmitivity.
Abstract:
A method is disclosed for forming a photoresist pattern with enhanced etch resistance on a semiconductor substrate. A photoresist pattern is first formed on the substrate. A silicon-containing polymer layer is deposited over the photoresist pattern on the substrate. A thermal treatment is performed to form a cross-linked anti-etch shielding layer between the photoresist pattern and the silicon-containing layer. Then, the remaining silicon containing layer is removed. A plasma treatment is performed in order to increase an etch resistance of the cross-linked anti-etch shielding layer and the photoresist pattern.

A pair of uniaxial 1/4λ compensation films is separately disposed on both outer surfaces of the dual domain ECB-LCD panel. A pair of uniaxial 1/2λ compensation films is separately disposed on outer surfaces of the pair of uniaxial 1/4λ compensation films. A pair of polarizers is separately disposed on both outer surfaces of the pair of the uniaxial 1/2λ optical compensation films.
Abstract:
The present invention includes a method of forming a resist structure comprising depositing a first photoresist material over a first layer. Selectively exposing portions of the first layer to light to provide exposed portions and unexposed portions in the first photoresist layer. Without developing the first photoresist layer, depositing a second photoresist layer over the first photoresist layer including both exposed portions and unexposed portions. The second photoresist layer being capable of crosslinking in the presence of an acid. Treating the first photoresist layer to cause an acid from only one of the exposed portions or unexposed portions of the first photoresist layer producing a plurality of crosslinked portions of the second photoresist layer. Thereafter, developing the second photoresist layer to remove uncrosslinked portions.
Abstract:
A method of processing a semiconductor wafer can be used prior to an immersion lithography process. The method includes providing a layer of organic photoresist onto a surface of the semiconductor wafer and removing a portion of the photoresist from an outer edge of the wafer using an edge-bead removal process. The outer edge of the wafer is then cleaned using one or more processes, including a mechanical scrubber/cleaner, mega-sonic power, de-ionized water and/or chemical solution.
