Abstract
A three-dimensional (3D) chip is fabricated from components that have been cut out of a two-dimensional (2D) chip. The components from the 2D chip are layered and coupled to create the layers of the 3D chip. By testing the 2D chip first, the layers of the 3D chip have been pre-tested, thus reducing testing and production costs.
