One such method includes selecting a die of a plurality of dies that are coupled together through a via stack. A via on the selected die can be coupled to ground. A supply voltage is coupled to an end of the via stack and a resulting current measured. A calculated resistance is compared to an expected resistance to determine if a fault exists in the via stack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Via stack fault detection","description":"A method and apparatus are disclosed.
