Abstract

A method of attaching a die to a substrate is disclosed. A major surface of the die has an array of electrical contacts, and is covered with a tape segment having an array of apertures in register with the contacts. Solder balls are inserted into the apertures. The die is positioned against a substrate with the solder balls in register with the die pads on the surface of the substrate, and a heat treatment process is performed to bond the conductive elements to the corresponding bond pads.

Claims
