Title: Semiconductor device and manufacturing method thereof
Inventor: EZAWA HIROKAZU
IPC: H01L23/52
Filed: 2000-09-22
Abstract: PURPOSE: To provide a semiconductor device and its manufacturing method by which a solder bump, a gold wire and a gold bump are connected to a copper pad without increasing the steps so that a high shear strength may be secured. CONSTITUTION: After a copper diffusion prevention film 4 is formed on a copper pad 1, a titanium film 5, a nickel film 6 and a paradium film 7 comprising a barrier metal are formed thereon. Thus, since the copper diffusion prevention film 4 is formed on the copper pad 1, the copper is prevented from being diffused by means of the copper diffusion prevention film 4. Even if a solder bump is formed on the copper pad 1, a tin and a copper in a solder can be prevented from being diffused. Therefore, an intermetallic compound is hardly formed between the copper and thin and no boundary peeling occurs, resulting in a highly reliable connection. In this case, this can be realized by an easy manufacturing process, which is different from a method for making a barrier metal to be thick using an electrical plating.
