Abstract

Embodiments of the present invention include multiple independent terminals for a plurality of devices in a stack configuration within a semiconductor. In one embodiment, a multi terminal fabrication process comprises: performing an initial pillar layer formation process to create layers of a multi terminal stack; forming a first device in the layers of the multi terminal stack; forming a second device in the layers of the multi terminal stack; and constructing a set of terminals comprising: a first terminal coupled to the first device, a second terminal coupled to the second device; and a third terminal coupled to the first device; wherein at least two terminals in the set of terminals are independent. The third terminal can be coupled to the second device.
