摘要:
A method for fabricating electrical bonding pads on the electrical contact areas of a wafer includes producing first blocks made of a solder material, producing second blocks made of a solder material on these first blocks, and passing the blocks through an oven so as to shape the blocks into approximately domed electrical bonding pads.
