Abstract:
Implementations of semiconductor packages may include: a silicon die including a pad, the pad including aluminum and copper; a passivation layer over at least a portion of the silicon die and a layer of one of a polyimide (PI) a polybenzoxazole (PBO), or a polymer resin coupled to the passivation layer. The package may include a first copper layer coupled over the pad, the first copper layer being about 1 microns to about 20 microns thick; a second copper layer coupled over the first copper layer, the second copper layer may be about 5 microns to about 40 microns thick; where a width of the first copper layer above the pad may be wider than a width of the second copper layer above the pad. The first and second copper layers may be configured to bond with a heavy copper wire or solder with a copper clip.

Claim (Index 8):
A method for making a semiconductor package, the method comprising:\n providing a die comprising a pad on a first side of the die, the pad comprising one of aluminum and copper (AlCu); aluminum, copper, and silicon (AlCuSi); aluminum, copper and tungsten (AlCuW); aluminum silicon (AlSi); and any combination thereof; applying a passivation layer over at least a portion of the first side of the die and over a portion of the pad; applying and patterning one of a polyimide (PI) layer and a polybenzoxazole layer (PBO) over the passivation layer; applying a seed layer on the pad; patterning a first photoresist layer over the seed layer; electroplating a first copper layer over the seed layer, the first copper layer having a thickness of between 1 microns and 20 microns; patterning a second photoresist layer over the first copper layer; electroplating a second copper layer over the first copper layer, the second copper layer having a thickness of between 5 microns and 40 microns; removing the first photoresist layer; removing the second photoresist layer; stripping the seed layer; back grinding a second side of the die; implanting one of boron, phosphorus, and boron and phosphorous into the second side of the die; annealing the die; evaporating a metal layer on the second side of the die, the metal layer comprising one of aluminum (Al), aluminum copper (AlCu), and any combination thereof; annealing the die after evaporating the metal layer; and forming a metallization layer on the aluminum layer through one of evaporation and sputtering; the metallization layer comprising one of titanium, nickel, and silver; titanium, nickel, and copper; titanium, nickel, and gold; and any combination thereof; wherein the second copper layer is configured to couple to one of a heavy copper wire and a copper clip.
