Latest Patents
One of Yoshikazu Shimote's latest patents focuses on a semiconductor device and its manufacturing method. This innovation enhances the joint reliability in flip chip bonding of semiconductor devices. The process involves applying flux to the solder bumps before flip chip bonding over a substrate, followed by reflow and cleaning. This method allows for thinning the oxide film on the solder bumps, resulting in a more uniform oxide film. Consequently, it suppresses the production of local solder protrusions, thereby reducing solder bridges during flip chip bonding and improving joint reliability.
Another patent by Shimote describes a semiconductor device that includes a solder resist film in contact with the base material layer and a resin body that interfaces with both the solder resist film and the semiconductor chip. The configuration ensures that the linear expansion coefficients of the materials are appropriately balanced, which helps to suppress damage caused by temperature cyclic loads. This innovation significantly improves the reliability of semiconductor devices.
