Patent ID: 8685837

Claim:
A method for transferring semiconductor elements, comprising: a depressed portion forming step of forming depressed portions in a surface of a semiconductor substrate on which the semiconductor elements are to be formed, and forming, on the semiconductor substrate, a plurality of island-shaped element sections which are integrally provided together with the semiconductor substrate as a single monolithic member and which are separated by the depressed portions, each of the plurality of island-shaped element sections includes at least one of the semiconductor elements; an intermediate transfer substrate bonding step of bonding together the surface of the semiconductor substrate on which the semiconductor elements are to be formed and an intermediate transfer substrate via an adhesive material layer whose adhesive force is capable of being decreased by external energy; an element-separating step of, by grinding the semiconductor substrate from a bottom wall side of the depressed portions, causing the element sections, which were connected together by bottom walls of the depressed portions, to be separated from each other; a final transfer substrate joining step of joining, to a final transfer substrate, only some of the plurality of element sections adhering to the intermediate transfer substrate; and a final transfer step of, by decreasing the adhesive force of the adhesive material layer by locally applying external energy to the adhesive material layer between said some of the element sections which have been joined to the final transfer substrate and the intermediate transfer substrate, selectively transferring said some of the element sections from the intermediate transfer substrate to the final transfer substrate; wherein the final transfer substrate joining step joins the final transfer substrate with the only some of the plurality of element sections adhering to the intermediate transfer substrate without the use of any adhesive material.
