Abstract:
A method for manufacturing a semiconductor chip, comprising the steps of:(a) placing a first semiconductor chip formed with a first electrode on a first surface such that said first surface is directed upward; (b) imaging said first surface from above to determine a position of said first electrode; (c) positioning, above said first semiconductor chip, a second semiconductor chip formed with a second electrode on a second surface such that said surface is directed downward; (d) imaging a back surface of said second semiconductor chip to determine a position of said second electrode; and (e) mounting said second semiconductor chip on said first semiconductor chip such that said first electrode and said electrode are connected to each other, wherein said step (d) includes the steps of (d-1) imaging from above said back surface, (d-2) recognizing at least part of contour of said second semiconductor chip, and (d-3) determining a position of said second electrode based on a result of a recognition at said step (d-2).
