Abstract
A first semiconductor tier has a first tier-to-tier connector for detecting a tier-to-tier coupling in a stacked integrated circuit (IC) device. A second semiconductor tier has a second tier-to-tier connector configured to electrically couple to the first tier-to-tier connector. A tier-to-tier detection circuit electrically couples to the second tier-to-tier connector. The tier-to-tier detection circuit generates an output signal indicative of an electrical coupling between the first semiconductor tier and the second semiconductor tier.
