Bare Al surfaces were contaminated with 2 levels of fluoride (7 × 10 15 and 3 × 10 16 at/cm 2) and these wafers were used together with a clean reference wafer for wire bonding. A few hours after the contamination, 10 series of 50 bond balls were applied with the same standard wire bond settings on all wafers. free elsa color sheet
