A first crystalline conductive film layer can be separated, along the line of fracture, from the crystalline nitride substrate and subsequently bonded to a layered stack including a traditional lower-cost substrate. If the spalled surface of the first crystalline conductive film layer is exposed in the resulting structure, the structure can act as a substrate on which high quality GaN-based devices can be grown."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Engineered substrates for use in crystalline-nitride based devices","description":"A spalling process can be employed to generate a fracture at a predetermined depth within a high quality crystalline nitride substrate, such as a bulk GaN substrate.
