Patent ID: 7049216

Claim:
A method of forming a solder structure, the method comprising: providing a wafer including a plurality of die therein; forming a solder wettable pad on at least one of the die adjacent an edge of the die, the solder wettable pad having a length parallel to the edge of the die and a width perpendicular to the edge of the die wherein the length parallel to the edge of the die is greater than the width perpendicular to the edge of the die; forming a solder bump on the solder wettable pad; after forming the solder bump on the solder wettable pad, separating the die from the wafer along the edge of the die; and after separating the die from the wafer, reflowing the solder bump on the solder wettable pad so that the solder bump extends laterally from the solder wettable pad toward the edge of the die.
