Latest Patents
One of Kazutoshi Ito's latest patents focuses on a semiconductor device and the method of manufacturing it. The invention describes a structure where a silicon chip and a metal leadframe are joined by a metallic bond through a porous joint layer made of high conductive metal. This layer features a three-dimensional network structure and utilizes silver as a bonding material. Additionally, a film containing zinc oxide or aluminum oxide is formed on the surface of the semiconductor assembly that contacts a polymer resin. This innovative joint layer, primarily composed of silver, reduces the thermal stress load on the silicon chip and enhances the fatigue life of the joint layer itself. Furthermore, the adhesion of the polymer resin to the film is improved through an anchor effect, which helps prevent cracks in the bonding portion, ultimately leading to a highly reliable lead-free semiconductor device.
