Abstract

A method of selectively transferring semiconductor devices comprises the steps of providing a substrate having a first surface and a second surface; providing a plurality of semiconductor epitaxial stacks on the first surface, wherein each of the plurality of semiconductor epitaxial stacks comprises a first semiconductor epitaxial stack and a second semiconductor epitaxial stack, and the first semiconductor epitaxial stack is apart from the second semiconductor epitaxial stack, and wherein a adhesion between the first semiconductor epitaxial stack and the substrate is different from a adhesion between the second semiconductor epitaxial stack and the substrate; and selectively separating the first semiconductor epitaxial stack or the second semiconductor epitaxial stack from the substrate.
