Latest Patents

Fukuda holds a patent for a semiconductor device and the manufacturing method of a semiconductor device. This invention features a solder joint layer with a unique structure where multiple fine-grained second crystal sections precipitate at the crystal grain boundaries of first crystal sections dispersed in a matrix. The first crystal sections consist of Sn crystal grains containing tin and antimony in a specific proportion. The second crystal sections are composed of either a portion containing a predetermined proportion of Ag atoms relative to Sn atoms or a portion containing a predetermined proportion of Cu atoms relative to Sn atoms, or both. Additionally, the solder joint layer may include third crystal sections that contain a predetermined proportion of Sb atoms with respect to Sn atoms. This innovative design allows for solder joining at a low melting point, resulting in a highly reliable solder joint layer with a substantially uniform metal structure.
