IPC: H01B13/00
Filed: 1979-02-13
Abstract: PURPOSE: To provide a shortened process for manufacturing semiconductor device by a method of forming multi-layer wiring, wherein a film of a metal having a high melting point and a film of other metal adjacent to the first-mentioned metal are formed in a single step by a resistance heating evaporation method with the use of alloy powders.  
     CONSTITUTION: A power mixture of Ti and W powders or powder of a Ti-W alloy are placed on a tungsten heater and heated by the latter. The Ti and W are evaporated as they are heated up to about 2000°C. As the shutter of the evaporation device is opened in this state, a Ti-W film is formed on the substrate. After a subsequent formation of Pd and Au films by evaporation, or the like, a 4-layer wiring construction of Ti-W-Pd-Au is constructed. Since the metals having high melting point constituting the multi-layer wiring are heated together with other metals, the electron-beam evaporation device and sputtering device are eliminated to permit a shortening of the production process.
