Filed: 1989-01-10
Abstract: PURPOSE:To realize microstructure, high rigidity, high reliability and low cost by forming a wiring layer and a bump electrode by diffusion bonding using high temperature press contact or diffusion bonding using ultrasonic wave vibration. CONSTITUTION:Both metals of a wiring layer and a bump electrode are brought into contact with each other by applying pressure, at a temperature equal to or lower than the melting point, and diffusion bonding is performed without fusing the metals. For example, an Au wire 8 and a capillary 9 of a special shape are used; a chip is heated at 350 deg.C; the inside of the capillary is coated with ceramic; by pressing, a bump-shaped electrode shaped in the capillary 9 is formed. Next, while cooling nitrogen is sent, the capillary is lifted, and the upper part of the bump electrode 6 is cut by a cutter 10. Thereby a semiconductor device having a microstructural bump electrode of low cost and high reliability can be obtained.
