Abstract

Provided is a method for manufacturing a semiconductor device which connects a first bond point and a second bond point by a wire. The method includes: a ball bonding step in which a crimping ball and a ball neck are formed at the first bond point by ball bonding; a thin-walled portion forming step in which a thin-walled portion having a reduced cross-sectional area is formed between the ball neck and the crimping ball; a wire tail separating step in which after a capillary is raised to unroll a wire tail, the capillary is moved in a direction to the second bond point, and the wire tail and the crimping ball are separated in the thin-walled portion; and a wire tail joining step in which the capillary is lowered and a side surface of the separated wire tail is joined onto the crimping ball.
