    Abstract: A method of manufacturing semiconductor device includes forming a multilayer photoresist structure including a metal-containing photoresist over a substrate. The multilayer photoresist structure includes two or more metal-containing photoresist layers having different physical parameters. The metal-containing photoresist is a reaction product of a first precursor and a second precursor, and each layer of the multilayer photoresist structure is formed using different photoresist layer formation parameters. The different photoresist layer formation parameters are one or more selected from the group consisting of the first precursor, an amount of the first precursor, the second precursor, an amount of the second precursor, a length of time each photoresist layer formation operation, and heating conditions of the photoresist layers. The multilayer photoresist structure is selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying developer to the selectively exposed multilayer photoresist structure to form the pattern.

    Abstract: Method of manufacturing semiconductor device includes forming photoresist layer over substrate. Forming photoresist layer includes combining first precursor and second precursor in vapor state to form photoresist material, wherein first precursor is organometallic having formula: MaRbXc, where M at least one of Sn, Bi, Sb, In, Te, Ti, Zr, Hf, V, Co, Mo, W, Al, Ga, Si, Ge, P, As, Y, La, Ce, Lu; R is substituted or unsubstituted alkyl, alkenyl, carboxylate group; X is halide or sulfonate group; and 1≤a≤2, b≥1, c≥1, and b+c≤5. Second precursor is at least one of an amine, a borane, a phosphine. Forming photoresist layer includes depositing photoresist material over the substrate. The photoresist layer is selectively exposed to actinic radiation to form latent pattern, and the latent pattern is developed by applying developer to selectively exposed photoresist layer to form pattern.

    Abstract: A method for forming a semiconductor device is provided. The methods includes forming a photoresist layer over a substrate. The photoresist layer includes a polymer and an photoacid generator (PAG). The polymer includes a polymer backbone, an etch resistance promoting group chemically bonded to the polymer backbone, and an acid labile group (ALG) chemically bonded to the etch resistance promoting group. The method further includes exposing a portion of the photoresist layer to a radiation to produce acid in exposed portion, baking the photoresist layer, resulting in cleavage of the ALG, and removing an portion of the photoresist layer to form a patterned photoresist layer.
