The semiconductor device further includes a contact structure disposed in the semiconductor body. The contact structure includes a metal region and a doped region. The metal region extends into the semiconductor body from a first side of the semiconductor body to at least the compound semiconductor layer which includes the channel region. The doped region is formed in the semiconductor body between the metal region and the channel region so that the channel region is electrically connected to the metal region through the doped region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Contact structures for compound semiconductor devices","description":"A semiconductor device includes a semiconductor body including a plurality of compound semiconductor layers and a two-dimensional charge carrier gas channel region formed in one of the compound semico","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9666705","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.
