Title: Innovations of Katsuyuki Inoue in Wafer Bonding Technology.
Introduction
Katsuyuki Inoue is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of wafer bonding technology, holding a total of 3 patents. His work focuses on methods that enhance the efficiency and effectiveness of wafer bonding processes.
Latest Patents
Inoue's latest patents include a method for bonding wafers and a wafer level package design. The method for bonding wafers involves forming a first bonding part on a surface of a first wafer by stacking a diffusion preventing layer made of a material with low wettability to AuSn. This is followed by creating a bonding layer on the diffusion preventing layer, ensuring that the bonding layer remains behind the edge of the diffusion preventing layer. A second bonding part is then formed on a second wafer, allowing for eutectic bonding between the two wafers using AuSn solder.
Another notable patent is the design of a wafer level package, which features a first wafer with multiple chips mounted in a plane, opposed by a second wafer. The two wafers are joined with a seal frame that encases the periphery of each chip, creating a gap between adjacent seal frames. This design includes a partial connect part that connects the seal frames of adjacent chips, enhancing the overall structure and functionality of the package.
