Abstract:
A method for manufacturing a bump on a terminal face of a semiconductor substrate, the method comprising:nucleating the terminal face to generate a basic metallization through electrolytic coating of the terminal face with zincate such that zinc particles electrolytically deposited on the terminal face serve as nuclei for an ensuing adhesion between the contact metallization autocatalytically deposited on the basic metallization and the terminal face; and electrolyticly coating of the terminal face with palladium such that, in addition to the deposition of zinc particles, palladium particles are deposited on the terminal face and serve as nuclei for ensuring adhesion between the contact metallization subsequently autocatalytically deposited on the basic metallization and the terminal face, wherein the basic metallization is formed by numerous independent zinc particles and numerous independent palladium particles.
