Abstract:
A method of mounting a semiconductor element comprising:forming a hole in a circuit board for connecting a circuit which is disposed on at least a front surface of said circuit board and a protruding bump on an electrode of the semiconductor element, affixing an external electrode terminal on the circuit board, opposite the front surface, for closing a side of said hole, filling said hole with a conductive paste for electrically connecting said external electrode terminal and said circuit on said front surface, positioning said protruding bump of said semiconductor element with said hole filled with said conductive paste, said semiconductor element being placed facing said front surface, pressing said semiconductor element to contact said conductive paste filled in said hole, thereby electrically connecting said electrode of said semiconductor element and said external electrode terminal of said circuit board; and heating at least one of said semiconductor element and said circuit board for curing said conductive paste.
