With a total of 2 patents, his work has implications for various technological applications.

Latest Patents

Fukase's latest patents include a photosensitive resin composition and a multilayer printed wiring board. The photosensitive resin composition is designed to exhibit excellent heat resistance and adhesion to wiring layers, yielding high resolution after development with an aqueous solution that contains no organic solvent. This composition serves as an adhesive between circuits in the production of multilayer printed wiring boards using a built-up method. The composition consists of a compound with at least one phenolic hydroxyl group and at least one acryloyl or methacryloyl group, an unsaturated imide compound, a photopolymerization initiator, and optionally, an epoxy compound with at least two epoxy groups.

Additionally, Fukase has developed a process for producing a piezo-electric or pyro-electric composite sheet. This process involves dispersing particles of a piezo-electric or pyro-electric sintered body in an insulating high polymeric substance, ensuring that the particles are in direct contact with electrodes on both sides of the sheet. The production method includes forming a sheet with the dispersed particles, removing the surface skin, and applying a voltage difference to effect poling of the sheet.
