摘要： A negative developable bottom antireflective coating (NDBARC) material includes a polymer containing an aliphatic alcohol moiety, an aromatic moiety, and a carboxylic acid moiety. The NDBARC composition is insoluble in a typical resist solvent such as propylene glycol methyl ether acetate (PGMEA) after coating and baking. The NDBARC material also includes a photoacid generator, and optionally a crosslinking compound. In the NDBARC material, the carboxylic acid provides the developer solubility, while the alcohol alone, the carboxylic acid alone, or their combination provides the PGMEA resistance. The NDBARC material has resistance to the resist solvent, and thus, intermixing does not occur between NDBARC and resist during resist coating over NDBARC. After exposure and bake, the lithographically exposed portions of both the negative photoresist and the NDBARC layer become insoluble in developer due to the chemically amplified crosslinking of the polymers in negative resist and NDBARC layer in the lithographically exposed portions.

摘要： The present invention relates to a developable bottom antireflective coating (BARC) composition and a pattern forming method using the BARC composition. The BARC composition includes a first polymer having a first carboxylic acid moiety, a hydroxy-containing alicyclic moiety, and a first chromophore moiety; a second polymer having a second carboxylic acid moiety, a hydroxy-containing acyclic moiety, and a second chromophore moiety; a crosslinking agent; and a radiation sensitive acid generator. The first and second chromophore moieties each absorb light at a wavelength from 100 nm to 400 nm. In the patterning forming method, a photoresist layer is formed over a BARC layer of the BARC composition. After exposure, unexposed regions of the photoresist layer and the BARC layer are selectively removed by a developer to form a patterned structure in the photoresist layer. The BARC composition and the pattern forming method are especially useful for implanting levels.

摘要： A photo resist composition contains at least one photoacid generator (PAG), wherein at least two photoacids are produced upon exposure of the photo resist to actinic energy and wherein the photo resist is capable of producing a hybrid response. The function of providing generation of two photoacids in a hybrid resist is to optimize the use of hybrid resist by varying the hybrid space width. The at least two photoacids may differ in their effectiveness at catalyzing at least one mechanism of the hybrid response. In particular, one photoacid may be a weaker acid and another may be a stronger acid, wherein there exists a difference of at least four orders of magnitude between the acid dissociation constant (Ka) of the weaker acid and the stronger acid. A method for optimizing space width in a hybrid photo resist includes the steps of: 1) selecting a desired space width; 2) selecting at least one photoacid generator (PAG), wherein at least two photoacids will be produced upon exposure to actinic energy in relative proportions sufficient to produce the desired space width in the hybrid photo resist; and 3) forming a hybrid photo resist composition comprising the at least one PAG. The step of selecting at least one PAG may include first determining the space width produced alone by each photoacid in a group of candidate photoacids and then selecting the photoacids and corresponding at least one PAG that will produce the desired space width.

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.
