This article delves into his latest patents, career highlights, and collaborations, shedding light on his valuable contributions to the world of semiconductors.
Latest Patents:
One of Kosaka's recent patents includes a semiconductor device fabricated by forming a metal film containing aluminum (Al) on a substrate product's surface. This metal film covers a via hole forming a predetermined region while an etching mask on the substrate's back surface exposes the via hole. By employing reactive ion etching, a via hole is formed in the substrate, reaching the surface from the backside and exposing the metal film. The utilization of a reaction gas containing fluorine during etching demonstrates Kosaka's innovative approach to semiconductor manufacturing.
Another recent patent focuses on a semiconductor device with a substrate featuring primary and secondary surfaces. By establishing a discontinuity within the substrate's via, Kosaka introduced a base metal layer and an additional metal layer with different wettability against solder. This design allows the base metal layer to come into contact with the solder while repelling it with the additional metal layer. The semiconductor device can be effectively assembled on an assembly substrate using this approach, demonstrating Kosaka's commitment to enhancing the die bonding process.
