  • Methods for forming pillar bumps on semiconductor wafers
    Patent number: 9831201
    Abstract: The subject matter contained herein discloses methods for forming a vertical metallic pillar overlying an under bump metal pad further overlying a semiconductor substrate, and applying a discrete solder cap on a top surface of the pillar, wherein the metallic pillar is defined by at least one photoresist layer. The method includes heating a multi-element metallic paste containing a variable amount of metallic powder, a melting point depressant and a flux such that the metal powder sinters to form the metallic pillar and simultaneously adheres the metallic pillar to the underbump metal pad.
    Type: Grant
