Abstract
A semiconductor single crystal structure may include a substrate; a defect trapping stack disposed on the substrate; and a semiconductor single crystal disposed on the defect trapping stack, and having a lattice mismatch with a crystal of the substrate, in which the defect trapping stack may include a first dielectric layer disposed on the substrate, and having at least one first opening, a second dielectric layer disposed on the first dielectric layer, and having at least one second opening, a third dielectric layer disposed on the second dielectric layer, and having at least one third opening, and a fourth dielectric layer disposed on the third dielectric layer, and having at least one fourth opening, and in which the semiconductor single crystal may extend to a region of the substrate defined in the at least one first opening through the at least one first to fourth opening.
