Title: The Innovations of Tadayasu Miki
Introduction
Tadayasu Miki is a prominent inventor based in Yamanashi, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work focuses on improving the manufacturing processes and designs of semiconductor devices.
Latest Patents
One of Miki's latest patents is a method of manufacturing through holes in a semiconductor device. This innovative process involves forming first through holes of a relatively small diameter and second through holes of a relatively great diameter in a first layer insulating film. The second through holes are tapered toward a layer underlying the first layer insulating film. Initially, the first through holes are formed and filled with plug electrodes, followed by the formation of the second through holes. The process ensures that the first conductive film deposited over the first layer insulating film is etched back to fill the first through holes, while residues on the side walls of the second through holes are removed.
Another notable patent is for a semiconductor integrated circuit that features three or more layers of wiring. This design includes a plurality of lines of bonding pads arranged along the outer peripheral portion of a semiconductor chip. The bonding pads are arranged in a zigzag manner, facilitating efficient electrical connections between the bonding pads and internal circuits. The innovative wiring structure enhances the performance and reliability of semiconductor devices.
