Latest Patents

Fukasawa's latest patents focus on a fabrication method of semiconductor devices. His innovations include a groundbreaking technique that allows die bonding to occur without the formation of voids in the bond area. The method incorporates a vacuum supply line connecting to a vacuum chuck hole located on the bottom face of a vacuuming collet, which supplies reduced pressure for vacuum chucking a chip during manufacturing. This system is structured into two main components: a first pipe and a second pipe, both linking to the vacuuming collet. The first pipe is responsible for supplying the collet with a vacuum that generates suction when a chip is unstuck from dicing tape and transported to a wiring substrate. The second pipe provides suction when the chip is mounted on the substrate. Furthermore, the vacuum intensity can be adjusted by the operation of valves installed within each pipe, ensuring precise control over the suction forces during the process.
