Latest Patents

Among Yoshihara's latest patents is the innovation titled "Ceramic electronic component and method for producing same." This patent details a ceramic electronic component that features a ground electrode layer, which can be directly coated with lead-free solder without compromising reliability. The invention includes a terminal electrode that incorporates a ground electrode layer made of copper, formed through firing, and a solder layer composed of a lead-free mixture of tin, silver, copper, nickel, and germanium.

One of its standout features is a diffusion layer formed by the diffusion of nickel between the ground electrode layer and the solder layer. This nickel diffusion layer acts as a barrier to prevent solder leaching of copper from the ground electrode, while also reducing the formation of brittle intermetallic compounds of tin and copper. This innovation ensures enhanced bonding strength between the ground electrode layer and the solder layer, reflecting Yoshihara's commitment to improving electronic component reliability.

Another recent patent exemplifies his expertise: the "Cleaning method." This patent describes a sophisticated process for cleaning wafers using a cleaning apparatus. The method involves utilizing a cleaning bath filled with a cleaning liquid, where the wafer undergoes treatment by oscillation and rotation while being held in place with brushes. This dual approach combines scrub cleaning with ultrasonic vibrations to enhance the cleaning efficiency, showcasing Yoshihara's innovative techniques in semiconductor manufacturing processes.
