  • Publication number: 20240118618
    Abstract: A method of manufacturing a semiconductor device includes forming a first layer having an organic material over a substrate. A second layer is formed over the first layer, wherein the second layer includes a silicon-containing polymer having pendant acid groups or pendant photoacid generator groups. The forming a second layer includes: forming a layer of a composition including a silicon-based polymer and a material containing an acid group or photoacid generator group over the first layer, floating the material containing an acid group or photoacid generator group over the silicon-based polymer, and reacting the material containing an acid group or photoacid generator group with the silicon-based polymer to form an upper second layer including a silicon-based polymer having pendant acid groups or pendant photoacid generator groups overlying a lower second layer comprising the silicon-based polymer. A photosensitive layer is formed over the second layer, and the photosensitive layer is patterned.

  • Publication number: 20240103375
    Abstract: A method of forming a patterned photoresist layer includes the following operations: (i) forming a patterned photoresist on a substrate; (ii) forming a molding layer covering the patterned photoresist; (iii) reflowing the patterned photoresist in the molding layer; and (iv) removing the molding layer from the reflowed patterned photoresist. In some embodiments, the molding layer has a glass transition temperature that is greater than or equal to the glass transition temperature of the patterned photoresist. In yet some embodiments, the molding layer has a glass transition temperature that is 3° C.-30° C. less than the glass transition temperature of the patterned photoresist.

  • Patent number: 11942322
    Abstract: In a method of manufacturing a semiconductor device, a metallic photoresist layer is formed over a target layer to be patterned, the metallic photoresist layer is selectively exposed to actinic radiation to form a latent pattern, and the latent pattern is developed by applying a developer to the selectively exposed photoresist layer to form a pattern. The metallic photo resist layer is an alloy layer of two or more metal elements, and the selective exposure changes a phase of the alloy layer.
