摘要： The present invention relates to a photoresist composition capable of negative development and a pattern forming method using the photoresist composition. The photoresist composition includes an imaging polymer, a crosslinking agent and a radiation sensitive acid generator. The imaging polymer includes a monomeric unit having an acid-labile moiety-substituted hydroxyl group. The patterning forming method utilizes an organic solvent developer to selectively remove an unexposed region of a photoresist layer of the photoresist composition to form a patterned structure in the photoresist layer. The photoresist composition and the pattern forming method are especially useful for forming material patterns on a semiconductor substrate using 193 nm (ArF) lithography.

摘要： A stack of a second photoresist having a second photosensitivity and a first photoresist having a first photosensitivity, which is greater than second photosensitivity, is formed on a substrate. A first pattern is formed in the first photoresist by a first exposure and a first development, while the second photoresist underneath remains intact. A second pattern comprising an array of lines is formed in the second photoresist. An exposed portion of the second photoresist underneath a remaining portion of the first photoresist forms a narrow portion of a line pattern, while an exposed portion of the second photoresist outside the area of the remaining portions of the photoresist forms a wide portion of the line pattern. Each wide portion of the line pattern forms a bulge in the second pattern, which increases overlay tolerance between the second pattern and the pattern of conductive vias.

摘要： A method and a resist composition. The resist composition includes a polymer having repeating units having a lactone moiety, a thermal base generator capable of generating a base and a photosensitive acid generator. The polymer has the properties of being substantially soluble in a first solvent and becoming substantially insoluble after heating the polymer. The method includes forming a film of a photoresist including a polymer, a thermal base generator capable of releasing a base, a photosensitive acid generator, and a solvent. The film is patternwise imaged. The imaging includes exposing the film to radiation, resulting in producing an acid catalyst. The film is developed in an aqueous base, resulting in removing base-soluble regions and forming a patterned layer. The patterned layer is baked above the temperature, resulting in the thermal base generator releasing a base within the patterned layer and the patterned layer becoming insoluble in the solvent.

摘要： A method suitable for reducing side lobe printing in a photolithography process is enabled by the use of a barrier layer on top of a photoresist on a substrate. The barrier layer is absorbing at the imaging wavelength of the underlying photoresist and thus blocks the light from reaching the photoresist. A first exposure followed by a development in an aqueous base solution selectively removes a portion of the barrier layer to reveal a section of the underlying photoresist layer. At least a portion of the revealed section of the photoresist layer is then exposed and developed to form a patterned structure in the photoresist layer. The barrier layer can also be bleachable upon exposure and bake in the present invention.

摘要： The present invention provides a method of forming a threshold voltage adjusted gate stack in which an external acid diffusion process is employed for selectively removing a portion of a threshold voltage adjusting layer from one device region of a semiconductor substrate. The external acid diffusion process utilizes an acid polymer which when baked exhibits an increase in acid concentration which can diffuse into an underlying exposed portion of a threshold voltage adjusting layer. The diffused acid reacts with the exposed portion of the threshold voltage adjusting layer providing an acid reacted layer that can be selectively removed as compared to a laterally adjacent portion of the threshold voltage adjusting layer that is not exposed to the diffused acid.

摘要： An anti-reflective coating material, a microelectronic structure that includes an anti-reflective coating layer formed from the anti-reflective coating material and a related method for exposing a resist layer located over a substrate while using the anti-reflective coating layer provide for attenuation of secondary reflected vertical alignment beam radiation when aligning the substrate including the resist layer located thereover. Such enhanced vertical alignment provides for improved dimensional integrity of a patterned resist layer formed from the resist layer, as well as additional target layers that may be fabricated while using the resist layer as a mask.
