Abstract
Abstract A multiple die package may include a pair of dies having bonding pads and a front surface on which the bonding pads are located. The front surface is facing the same direction. At least one of the dies is secured to a lead frame. A spacer spaces the die from one another. At least one of the dies is spaced from the leadframe by a distance greater than the thickness of the die.
