Latest Patents

One of Koyama's latest patents is for an adhesive and light-emitting device. This innovative adhesive contains an epoxy compound, a cationic catalyst, and an acrylic resin that includes acrylic acid and an acrylic acid ester with a hydroxyl group. The unique composition allows the acrylic acid in the acrylic resin to react with the epoxy compound, creating a strong link between the two components. This design enhances the anchoring effect with respect to the epoxy compound by roughening the surface of an oxide film. Additionally, the hydroxyl-group-containing acrylic acid ester becomes electrostatically adhesive to wiring, resulting in excellent adhesive strength.

Another notable patent is for an underfill material and method for manufacturing semiconductor devices. This underfill material consists of an epoxy resin, an acid anhydride, an acrylic resin, and an organic peroxide. The material achieves a wide margin for mounting, with specific temperature and viscosity characteristics that allow for voidless mounting and good solder bonding properties. This innovation simplifies the manufacturing process by reducing the need for strict temperature control during thermocompression bonding.
