The wafers are aligned to a desired orientation and the two layers are held in contact with one another. The aluminum-germanium interface is heated to a temperature that allows the interface of the layers to melt, thus forming a bond. A portions of the germanium layer may be removed from the second wafer to allow infrared radiation to pass through the second wafer to facilitate wafer alignment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of bonding wafers","description":"A method of bonding wafers with an aluminum-germanium bond includes forming an aluminum layer on a first wafer, and a germanium layer on a second wafer, and implanting the germanium layer with non-ger","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8507913","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.
