In one example, the predefined depth and width of the trenches is such so as to increase the surface area of the second side of the substrate by at least 20 percent. In one example, the method also includes providing a layer of a thermal interface material (TIM) on the second side of the substrate, including to fill at least a portion of the trenches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thermal enablement of dies with impurity gettering","description":"In one example, a method includes providing a first side of a semiconductor substrate with a plurality of transistors, etching a second side of the substrate, opposite the first side, with a pattern o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11488887","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
