Title: Kei Kawase: Innovator in Semiconductor Technology
Introduction
Kei Kawase is a prominent inventor based in Sagamihara, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 16 patents. His work focuses on developing innovative solutions that enhance the performance and reliability of electronic devices.
Latest Patents
One of his latest patents is a mounting structure and mounting structure manufacturing method. This invention aims to reduce the mechanical stress added to a low-κ material due to warping caused by the difference in thermal expansion coefficients between a chip and a chip support during mounting. The mounting structure includes a low-κ layer formed on top of a semiconductor substrate, an electrode layer formed on the low-κ layer, and a protective layer with an opening reaching the electrode layer. Additionally, it features a first solder layer filling the opening and formed on the electrode layer, a second solder layer with a smaller elastic modulus than the first, and a support layer connected to the second solder layer that supports the semiconductor substrate. The protective layer has a greater elastic modulus and a smaller thermal expansion coefficient than an underfill layer formed between the protective layer and the support layer.
Another notable patent is for an image data transmission apparatus and method for an image display system. This system comprises a transmission device, such as a PC, which transmits image data upon receiving a drawing command from an operating system or application. The receiving monitor displays the image data on a high-resolution panel. The transmission device includes a drawing command analysis device that detects areas on the screen where content changes and calculates the area to be transmitted. The graphics card then transmits a packet that includes the calculated area and control data as header data. The receiving monitor analyzes the header data in the received packet and renders the image data based on this information.
