Title: Tetsuya Yano: Innovator in Semiconductor Technology

Introduction

Tetsuya Yano is a prominent inventor based in Kofu, Japan. He has made significant contributions to the field of semiconductor technology, particularly through his innovative methods for forming multilevel interconnections.

Latest Patents

Yano holds a patent for a "Multilevel interconnection forming method for forming a semiconductor." This method involves several steps, including the deposition of a metal film containing aluminum on an insulating film of a substrate. The process includes patterning the metal film to create a wiring layer of the first layer, followed by the formation of an interlayer dielectric film that covers the wiring layer. A hole is then created in the dielectric film, allowing for selective deposition of aluminum into the hole using a CVD method. The method ensures that the aluminum fills the hole at a volume ratio smaller than 100%. An active metal film is subsequently formed, and a metal layer containing aluminum is created on top. The metal layer is then reflowed to fill the hole completely and to planarize the surface, leading to the formation of a second wiring layer.
