Abstract
An inexpensive method of providing uniform and consistent spacing between a semiconductor die and a supporting substrate includes providing relatively rigid spacers such as a plurality of lengths of wires or a plurality of bumps on the mounting surface for the chip. The spacers allow a uniform desired spacing of the die from the supporting substrate when attached by an epoxy.
