  • Patent number: 8227307
    Abstract: 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.

  • Patent number: 8227180
    Abstract: 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.

  • Publication number: 20120178027
    Abstract: A method. The method forms a film of photoresist composition on a substrate and exposes a first and second region of the film to radiation through a first and second mask having a first and second image pattern, respectively. The photoresist composition includes a polymer including labile group(s), base soluble group(s), a photosensitive acid generator, and a photosensitive base generator. The photosensitive acid generator generates first and second amounts of acid upon exposure to first and second doses of radiation, respectively. The second amount of acid exceeds the first amount of acid. The second dose of radiation exceeds the first dose of radiation. The photosensitive base generator generates a first and second amount of base upon exposure to the first and second dose of radiation, respectively. The first amount of base exceeds the first amount of acid. The second amount of acid exceeds the second amount of base.

  • Publication number: 20120122031
    Abstract: 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 and a radiation sensitive acid generator. The imaging polymer includes a first monomeric unit having a pendant acid labile moiety and a second monomeric unit containing a reactive ether moiety, an isocyanide moiety or an isocyanate moiety. The patterning forming method utilizes an organic solvent developer to selectively remove unexposed regions 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.

  • Patent number: 8163466
    Abstract: A method forms a first patterned mask (comprising rectangular features and/or rounded openings) on a planar surface and forms a second patterned mask on the first patterned mask and the planar surface. The second patterned mask covers protected portions of the first patterned mask and the second patterned mask reveals exposed portions of the first patterned mask. The method treats the exposed portions of the first patterned mask with a chemical treatment that reduces the size of the exposed portions to create an altered first patterned mask.

  • Patent number: 7838198
    Abstract: 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.
