    Abstract: A method of manufacturing a semiconductor device includes forming a first protective layer over an edge portion of a first main surface of a semiconductor substrate. A metal-containing photoresist layer is formed over the first main surface of the semiconductor substrate. The first protective layer is removed, and the metal-containing photoresist layer is selectively exposed to actinic radiation. A second protective layer is formed over the edge portion of the first main surface of the semiconductor substrate. The selectively exposed photoresist layer is developed to form a patterned photoresist layer, and the second protective layer is removed.

    Abstract: A method for forming a semiconductor device structure is provided. The method includes forming a material layer over a substrate and forming a resist layer over the material layer. The resist layer includes an inorganic material and an auxiliary. The inorganic material includes a plurality of metallic cores and a plurality of first linkers bonded to the metallic cores. The method includes exposing a portion of the resist layer. The resist layer includes an exposed region and an unexposed region. In the exposed region, the auxiliary reacts with the first linkers. The method also includes removing the unexposed region of the resist layer by using a developer to form a patterned resist layer. The developer includes a ketone-based solvent having a formula (a), wherein R1 is linear or branched C1-C5 alkyl, and R2 is linear or branched C3-C9 alkyl.

    Abstract: A method for forming a semiconductor device is provided. The method includes applying a photoresist composition over a substrate, thereby forming a photoresist layer over the substrate; performing a first baking process to the photoresist layer; exposing the photoresist layer to an extreme ultraviolet (EUV) radiation, thereby forming a pattern therein; performing a second baking process to the photoresist layer; and developing the photoresist layer having the pattern therein using a developer, thereby forming a patterned photoresist layer. The first baking process and the second baking process are conducted under an ambient atmosphere having a humidity level ranging from 55% to 100%.

    Abstract: A method includes providing a layered structure on a substrate, the layered structure including a bottom layer formed over the substrate, a hard mask layer formed over the bottom layer, a material layer formed over the hard mask layer, and a photoresist layer formed over the material layer, exposing the photoresist layer to a radiation source, developing the photoresist layer, where the developing removes portions of the photoresist layer and the material layer in a single step without substantially removing portions of the hard mask layer, and etching the hard mask layer using the photoresist layer as an etch mask. The material layer may include acidic moieties and/or acid-generating molecules. The material layer may also include photo-sensitive moieties and crosslinking agents.

    Abstract: A method of manufacturing a semiconductor device includes forming a photoresist underlayer including a photoresist underlayer composition over a semiconductor substrate and forming a photoresist layer comprising a photoresist composition over the photoresist underlayer. The photoresist layer is selectively exposed to actinic radiation, and the photoresist layer is developed to form a pattern in the photoresist layer. The photoresist underlayer composition includes: a first polymer having one or more of pendant acid-labile groups and pendant epoxy groups, a second polymer having one or more crosslinking groups, an acid generator, a quencher or photodecomposable base, and a solvent. The photoresist underlayer composition includes 0 wt. % to 10 wt. % of the quencher or photodecomposable base based on a total weight of the first and second polymers.
