Abstract:
1. A method of transferring elements, comprising the steps of: holding a plurality of elements made at a first pitch on an element formation substrate on a temporary holding substrate in a state in which the first pitch is held although said plurality of elements are partitioned into pieces; forming a plurality of element mounting bases, each having a planar shape having a size smaller than the first pitch, and each having a bearing surface slightly higher than a surface of a main portion of an element disposition substrate in a periphery of the element mounting base at a second pitch equal to an integral multiple of the first pitch on the surface of said main portion of said element disposition substrate; disposing an uncured adhesive agent layer on each of said bearing surfaces of said element mounting bases; making said temporary holding substrate and said element disposition substrate close to each other in a state in which principal surfaces of said temporary holding substrate and said element disposition substrate face each other, and causing some of said plurality of elements to come in contact with said uncured adhesive agent layer; curing said uncured adhesive agent layer, fixing the elements contacting said adhesive agent layer to the element mounting bases, respectively; and separating said temporary holding substrate and said element disposition substrate from each other with the elements contacting said adhesive agent layer being left on the respective element mounting bases.
