Title: Reiji Tamaki: Innovator in Semiconductor Technology
Introduction
Reiji Tamaki is a prominent inventor based in Hyogo, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on improving the performance and reliability of semiconductor devices.
Latest Patents
One of his latest patents involves a semiconductor device with improved immunity to contact and conductor. In this invention, an impurity diffused layer serving as an active region is formed in a predetermined region of the surface of a silicon semiconductor substrate. An underlayer insulating film is created on the semiconductor substrate to protect and stabilize its surface. An interconnection, which is electrically connected to the impurity diffused layer through a contact hole, is formed on an Al-Si-Sn alloy, an Al-Si-Sb alloy, or alloys with added titanium. This design prevents the occurrence of alloy pits and silicon nodules. Additionally, a completed protective film is formed on the interconnection and the underlayer insulating film, with an aperture in a bonding pad region to ensure electrical connection between the interconnection and the bonding pad. The proportions of silicon and other materials in the alloy are carefully controlled to avoid defects both at the contact hole and throughout the alloy conductor.
