Abstract
A multi-die integrated circuit device and a method of fabricating the multi-die integrated circuit device involve a substrate. Two or more dice include components that implement functionality of the multi-die integrated circuit. The components include logic gates. The multi-die integrated circuit device also includes a spacer disposed between the substrate and each of the two or more dice. Each of the two or more dice makes direct electrical contact with the substrate without making direct electrical contact with the spacer through holes in the spacer.
