Latest Patents

Nishikawa holds a patent for a "Protected polyvinyl alcohol auxiliary for forming fine pattern and process for producing the same." This innovative patent describes a modified PVA that is protected with a specific protecting group. The modified PVA contains high-molecular weight body components with a weight-average molecular weight of 250,000 or more, limited to 1000 ppm or less. The preparation process involves removing metal ions and acids through ion exchange treatment, followed by heat treatment at temperatures of 80°C or higher. The resulting auxiliary for fine pattern formation includes the modified PVA, a water-soluble crosslinking agent, and a solvent mixture. This technology allows for the creation of hole patterns with high precision, achieving resolutions below the limits of light exposure.
