ABSTRACT:
Flip chip bumps (24, 26, and 27) and an inductor (17) are simultaneously fabricated on a semiconductor substrate (10). The fabrication process includes two electroplating steps. The first step electroplates copper (18) onto a seed layer (13) to form the inductor (17) and a first portion (16) of the flip chip bumps (24, 26, and 27). The second step electroplates copper (21) onto the previously electroplated copper (18) to form a second portion (21) of the flip chip bumps (24, 26, and 27).
