The semiconductor composite film includes: a semiconductor substrate; and a semiconductor epitaxial layer, which is formed on the semiconductor substrate, and it has a first surface and a second surface opposite to each other, wherein the heterojunction is formed between the first surface and the semiconductor substrate, and wherein the semiconductor epitaxial layer further includes at least one recess, which is formed by etching the semiconductor epitaxial layer from the second surface toward the first surface. The recess is for mitigating a strain in the semiconductor composite film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor composite film with heterojunction and manufacturing method thereof","description":"The present invention discloses a semiconductor composite film with a heterojunction and a manufacturing method thereof.
