Patent JP-S63114144-A (JP)
Title: Manufacture of semiconductor device
Inventor: SHIMA SHOHEI
IPC: H01L23/52
Filed: 1986-10-31
Abstract: PURPOSE:To decrease crystal grain boundaries having a large number of defects existing in a metallic wiring, and to improve the reliability of the metallic wiring by previously arranging and forming a plurality of fine grooves in parallel to each other to the surface of an insulator layer before shaping a metallic wiring layer. CONSTITUTION:A plurality of fine grooves 13 are disposed and shaped in parallel to each other to the surface of a insulator layer 12, and an Al film 14 is formed onto the insulator layer 12 through a sputtering method. When a semiconductor substrate is heated during sputtering at that time, an effect that surface mobility is increased is displayed at a time when sputtering Al atoms are shaped onto the insulator layer, and a crystal orientation is made easy to be further aligned. Accordingly, since separate crystal grain constituting a metallic wiring layer mutually has approximately the same crystal orientation, there hardly exist crystal defects on the crystal grain boundaries, and the wiring approximately close to a single crystal can be formed, thus preventing the generation of defective such as stress migration, then improving the reliability of the wiring.
