With a notable patent to his name, he has made significant advancements in creating metal-ceramics composite substrates, demonstrating his expertise and commitment to innovation.
Latest Patents
Ono holds a patent for "Brazing materials for producing metal-ceramics composite substrates." This innovation involves a brazing material comprising 0.25-0.9 wt % of titanium oxide added to a formula consisting of 60-94.25 wt % silver (Ag), 5-30 wt % copper (Cu), and 0.5-4.5 wt % of an active metal. The process entails forming a paste from the brazing material, which is applied to an aluminum nitride (AlN) substrate and overlaid with a copper plate. Upon heat treatment, a strong joint is formed between the AlN substrate and the copper plate. Furthermore, a resist is used on the copper plate to create a circuit pattern, which is then etched to produce a metallized circuit. This innovative method results in a metal-ceramics composite substrate that shows enhanced performance characteristics for high electrical power applications compared to conventional brazing materials.
