Latest Patents
Karashima's latest patents include a groundbreaking semiconductor package with a metal foil attachment film. This invention features a semiconductor device that comprises a semiconductor chip with an active and a passive surface. The passive surface is adhesively attached to a substrate film using a multilayer composite, which includes a metal foil with adhesive layers on both surfaces. This design enhances the stress distribution in solder joints, thereby improving solder fatigue life.
Another notable patent is a method of manufacturing a semiconductor chip with multiple bonding pads arranged in staggered rows on the edges. This innovative approach allows for the stacking of multiple stud bumps on the inner rows of bonding pads. The conductive wires connect the lands on the insulated substrate to the corresponding bonding pads, ensuring that the ends of the conductive wires on the inner pads are positioned higher than those on the outer pads. This arrangement effectively prevents neighboring conductive wires from coming into contact.
