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. 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.

摘要： Fluorine-free photoacid generators and photoresist compositions containing fluorine-free photoacid generators are enabled as alternatives to PFOS/PFAS photoacid generator-containing photoresists. The photoacid generators are characterized by the presence of a fluorine-free aromatic sulfonate anionic component having one or more electron withdrawing groups. The photoacid generators preferably contain a fluorine-free onium cationic component, more preferably a sulfonium cationic component. The photoresist compositions preferably contain an acid sensitive imaging polymer having a lactone functionality. The compositions are especially useful for forming material patterns using 193 nm (ArF) imaging radiation.
