摘要:
A method of protecting sensitive components prior to, during or subsequent to advanced die packaging processing includes applying a metal stack layer such as titanium/copper (Ti/Cu) onto the front surface of a die assembly such that the die assembly front surface is covered with the metal stack layer. A layer of titanium/copper/titanium (Ti/Cu/Ti) or a solder alloy is also applied to the back surface of the die assembly such that the back surface of the die assembly is covered with the Ti/Cu/Ti layer or solder alloy. The front surface metal stack layer and the back surface Ti/Cu/Ti layer or solder alloy prevent degradation of die metallization prior to, during or subsequent to the advanced die packaging processing.
