Patent 7378734 was granted and assigned to Touchdown Technologies on May, 2008 by the United States Patent and Trademark Office.
A novel method for providing bump structures that can be formed by conventional stud bump bonding techniques is disclosed. The bumps can be arranged in a buttressed configuration that allows for substantial lateral and vertical contact loads, and substantial heights. A side-by-side configuration may be used to build a stacked bump contact that is substantially taller and stronger than is possible under current techniques. Other arrangements can be selected to optimize the load bearing capacity in any direction or combination of directions.
