Title: Manufacturing device for semiconductor integrated circuit device
Inventor: TOMIYAMA TOMOHIKO
IPC: H01L21/31
Filed: 1988-04-25
Abstract: PURPOSE:To prevent white powder in the vicinity of a dispersion head generated through vapor phase reaction from attaching onto a wafer surface, and to increase the production yield, by making a film grow with a wafer surface facing in the direction of gravity. CONSTITUTION:The film-growing surface of a wafer 1 is made to face in the direction of gravity, and it is vacuum-sucked by a susceptor 2 and fixed. A vacuum of 40 to 60cmHg for this is supplied through piping 5. Many similar susceptors 2 are attached, and film growth on a wafer 1 is performed while the susceptors 2 are moving at a constant speed. At that time, since the surface of the wafer 1 faces the gas discharging opening 6 of a dispersion head and is directed in the direction of gravity, even if reaction powder produced by reaction on reaction gas is produced in the vicinity of the dispersion head, the reaction powder does not fall on the film-growing surface of the wafer 1 and does not attach to it. And, this increases the production yield.

Title: Metal wiring for semiconductor device and formation thereof
Inventor: KAN YORU I
IPC: H01L21/3205
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To eliminate grain boundary by branching a current path while forming a plurality of spaces each having a predetermined shape so that the spaces allow part of a conductive layer to be removed. SOLUTION: The predetermined shape is rectangular. It is desirable to form rectangular spaces 24 so as to juxtapose in a matrixlike form. That is, a current path is branched by the spaces 24. Each space 24 is longer than the grain size, and the interval between spaces is smaller than the grain size. As a result, the spaces 24 remove areas where grain boundary 25 cluster in a complicated way. The portion between the long sides of spaces and between the long side and edge form a so-called 'bamboo structure', and this 'bamboo structure' contributes to reducing electromigration. The spaces 24 are formed to provide the 'bamboo structure' over metal wiring 23a. While the length of the space 24 can be appropriately selected, the interval between the spaces 24 needs to be smaller than the grain size so that the 'bamboo structure' can be formed.
