  • Patent number: 10236184
    Abstract: Initial film layers prepared from tin(II) chloride spontaneously generate open cavities when the initial film layers are thermally cured to about 400° C. using a temperature ramp of 1° C./minute to 10° C./minute while exposed to air. The openings of the bowl-shaped cavities have characteristic dimensions whose lengths are in a range of 30 nm to 300 nm in the plane of the top surfaces of the cured film layers. The cured film layers comprise tin oxide and have utility in gas sensors, electrodes, photocells, and solar cells.

  • Patent number: 9389516
    Abstract: A process and composition for negative tone development comprises providing a photoresist film that generates acidic sites. Irradiating the photoresist film patternwise provides an irradiated film having exposed and unexposed regions where the exposed regions comprise imaged sites. Baking the irradiated film at elevated temperatures produces a baked-irradiated film comprising the imaged sites which after irradiating, baking, or both irradiating and baking comprise acidic imaged sites. Treating the baked-irradiated film with a liquid, gaseous or vaporous weakly basic compound converts the acidic imaged sites to a base treated film having chemically modified acidic imaged sites. Applying a solvent developer substantially dissolves regions of the film that have not been exposed to the radiant energy, where the solvent developer comprises a substantial non-solvent for the chemically modified acidic imaged sites.

  • Patent number: 8900802
    Abstract: Provided is a method for developing positive-tone chemically amplified resists with an organic developer solvent having at least one polyhydric alcohol, such as ethylene glycol and/or glycerol, alone or in combination with an additional organic solvent, such as isopropyl alcohol, and/or water. The organic solvent developed positive tone resists described herein are useful for lithography pattern forming processes; for producing semiconductor devices, such as integrated circuits (IC); and for applications where basic solvents are not suitable, such as the fabrication of chips patterned with arrays of biomolecules or deprotection applications that do not require the presence of acid moieties.
