Abstract:
Methods and system for flip chip alignment for substrate and leadframe applications are disclosed and may include placing a semiconductor die on bond fingers of a metal leadframe, wherein at least two of the bond fingers comprise one or more recessed self-alignment features. A reflow process may be performed on the semiconductor die and leadframe, thereby melting solder bumps on the semiconductor die such that a solder bump may be pulled into each of the recessed self-alignment features and aligning the solder bumps on the semiconductor die to the bond fingers. The recessed self-alignment features may be formed utilizing a chemical etch process or a stamping process. A surface of the recessed self-alignment features or the bond fingers of the metal leadframe may be roughened. A solder paste may be formed in the recessed self-alignment features prior to placing the semiconductor die on the bond fingers of the metal leadframe.

Claim (Index 30):
The electronic device of  claim 28 , wherein each of the curved sidewall recessed self-alignment features is stamped into its respective bond finger.
