Latest Patents

Tarou Itatani holds a patent for a "Method for forming polyimide pattern using photosensitive polyimide and composition for use therein." This invention relates to a photosensitive polyimide material that exhibits either positive-type or negative-type photosensitivity. The material can be developed with high resolution using short wavelength irradiation energy, such as ultraviolet light or electron beams. The positive-type photosensitive polyimide composition includes a solvent-soluble polyimide that shows positive-type photosensitivity in the presence of a photoacid generator. This generator is obtained through the polycondensation of at least one aliphatic tetracarboxylic dianhydride and/or alicyclic tetracarboxylic dianhydride, along with at least one aliphatic diamine and/or alicyclic diamine and/or diaminosiloxane. Additionally, the polyimide can demonstrate negative-type photosensitivity when irradiated with an electron beam in the absence of a photoacid generator, allowing for the formation of negative-type polyimide patterns.
