摘要:
A method for manufacturing a marked single-crystalline substrate comprises providing a single-crystalline substrate comprising a first material, the single-crystalline substrate having a surface area; forming a marking structure on the surface area of the single-crystalline substrate, wherein the marking structure comprises a first semiconductor material; and depositing a semiconductor layer on the marking structure and at least partially on the surface area of the single-crystalline substrate, wherein the semiconductor layer comprises the second semiconductor material, and wherein the marking structure is buried under the second semiconductor material.
