Title: Method of fabricating semiconductor device
Inventor: YAMAMOTO YOSHIAKI
IPC: H01L21/768
Filed: 2003-02-26
Abstract: A method of fabricating a semiconductor device prevents agglomeration of a seed metal layer in a recess. A recess is formed in a dielectric layer formed on or over a wafer. A seed metal layer (e.g., Cu or Cu alloy) is then formed on a bottom face and an inner side face of the recess. Subsequently, a surface of the seed metal layer is oxidized by exposing the surface of the seed metal layer to an oxygen- containing gas or the atmospheric air before agglomeration of the seed metal layer occurs, thereby forming an oxide layer in the surface of the seed metal layer. A filling metal (e.g., Cu or Cu alloy) is plated on the oxide layer of the seed metal layer while using the seed metal layer whose surface is oxidized as an electrode, thereby filling the recess with the metal.

Title: Grain agitating apparatus and grain storing apparatus
Inventor: YAMAMOTO SOICHI
IPC: A01F25/00
Filed: 2003-03-19
Abstract: In an agitating machine, an axial direction of a drive roll is inclined to one side or another side with respect to an axial direction of a guide shaft which is rotated on its own axis, whereby a drive support machine casing and a driven support machine casing are moved to one end side or another end side of the guide shaft. When an arrival detecting apparatus detects that the drive support machine casing or the driven support machine casing has reached the one end side or the another end side of the guide shaft, a control apparatus drives a reversing motor so as to incline the axial direction of the drive roll to the another side or the one side. Since the arrival detecting apparatus, the reversing motor and the control apparatus are electronically driven, it is possible to securely incline the axial direction of the drive roll.
