Title: The Innovative Contributions of Koji Shibasaki
Introduction
Koji Shibasaki is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 9 patents. His work focuses on enhancing the efficiency and reliability of integrated circuit devices.
Latest Patents
Shibasaki's latest patents include a flip-chip connection type semiconductor integrated circuit device. This invention involves forming a first insulating film on an integrated circuit chip with an I/O pad. A first opening portion is created above the I/O pad, and a conductive layer along with a barrier metal layer is stacked on the first insulating film. These layers are patterned using a single mask. A second insulating film is then formed, with a second opening portion positioned differently from the first. A solder bump or metal pad is created on the barrier metal layer in the second opening portion, which is defined by this second opening.
Another notable patent is an apparatus and method for inspecting an LSI device during assembly. This invention includes a mechanism for inspecting the connection state of a lead electrode to a bump after tape automated bonding (TAB). The LSI chip is immobilized on a stage, and a flexible lead is held and connected to a bump. A CCD camera is positioned above the chip to capture images of the lead/bump connection states. The stage is controlled to move, allowing for the comparison of images to determine if the lead is properly connected to the bump.
