It is determined whether there is a wurtzite III-nitride alloy composition satisfying the selected effective piezoelectric coefficient. It is also determined whether there is a thickness for a layer formed from the wurtzite III-nitride alloy composition satisfying the selected piezoelectric polarization based on the selected substrate and the selected effective piezoelectric coefficient. Responsive to the determination that there is a wurtzite III-nitride alloy composition having a lattice constant satisfying the selected effective piezoelectric coefficient and a thickness for the layer formed from the wurtzite III-nitride alloy composition satisfying the selected piezoelectric polarization, the wurtzite III-nitride alloy layer is formed on the substrate having the wurtzite III-nitride alloy composition satisfying the selected effective piezoelectric coefficient and having the thickness satisfying the selected piezoelectric polarization."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Forming III nitride alloys","description":"A method for forming a semiconductor device involves selecting a substrate on which a wurtzite III-nitride alloy layer will be formed, and a piezoelectric polarization and an effective piezoelectric c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11264238","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.
