  • Patent number: 10655019
    Abstract: A coating technique and a priming material are provided. In an exemplary embodiment, the coating technique includes receiving a substrate and applying a priming material to the substrate. The applying of the priming material may include rotating the substrate to disperse the priming material radially on the substrate. In the embodiment, the priming material includes a solvent with at least six carbon atoms per molecule. A film-forming material is applied to the substrate on the priming material, and the application includes rotating the substrate to disperse the film-forming material radially on the substrate. The priming material and the film-forming material are evaporated to leave a component of the film-forming material in a solid form. In various embodiments, the priming material is selected based on at least one of an evaporation rate, a viscosity, or an intermolecular force between the priming material and the film-forming material.

  • Patent number: 10394126
    Abstract: One of the broader forms of the present disclosure relates to a method of making a semiconductor device. The method includes exposing a photoresist layer to a radiation source and applying a hardening agent to the photoresist layer. Therefore after applying the hardening agent a first portion of the photoresist layer has a higher glass transition temperature, higher mechanical strength, than a second portion of the photoresist layer.

  • Patent number: 9772559
    Abstract: Methods for performing a photolithographic process are disclosed. The methods facilitate the removal of photosensitive from a wafer after the photosensitive has been used as an etch mask. The photosensitive may be a negative tone photosensitive that undergoes a cross-linking process on exposure to electromagnetic energy. By limiting the cross-linking through a reduced post-exposure bake temperature and/or through reduced cross-linker loading, the photoresist, or at least a portion thereof, may have a reduced solvent strip resistance. Because of the reduced solvent strip resistance, a portion of the photosensitive may be removed using a solvent strip. After the solvent strip, a dry etch may be performed to remove remaining portions of the photoresist.

  • Patent number: 9731231
    Abstract: A filtering unit is provided which may include a filter cap, a filter basin, a filter or membrane within the filter basin and an enclosed fluid intake channel, which may dispense fluid into the filter basin. The enclosed fluid intake channel may be coupled to the inlet port of the filtering unit and may slope in a downward manner to the bottom of the filter basin. The intake channel may have an open end at the bottom of the filter basin. The open end may be substantially parallel with the filter basin bottom and may dispense fluid into the filter basin. The fluid may flow from the intake channel and into the filter basin in a laminar manner. The fluid may fill the filter basin and flow from the filtering unit through an outlet port of the filtering unit.
