In one example, a stacked IC device is provided that includes a first wafer, a second wafer, and first conductive bridge. The second wafer is stacked on and secured to the first wafer. The second wafer has a plurality of IC dice that are communicatively coupled to a plurality of IC dice formed on the first wafer. The first conductive bridge has a first end that is sandwiched between the first and second wafers. The first conductive bridge shorts exposed pads of dice formed in the exclusion zones of the first and second wafers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wafer to wafer stacking","description":"Embodiments herein describe techniques for wafer to wafer stacking of integrated circuit chips (e.g., dice) to form stacked IC devices.
