Mounting method of semiconductor element










Image Number 13 for United States Patent #6531022.

A mounting method of a semiconductor element capable of joining an electrode of a semiconductor element and a circuit board at high reliability. The method includes a step of forming an external electrode terminal by filling a hole formed in circuit board with a conductive paste, a step of positioning the external electrode terminal and a protruding bump formed on an electrode of a semiconductor, and a step of pressing the semiconductor element to contact between the conductive paste in the hole and the protruding bump thereby electrically connecting the electrode of the semiconductor element and the external electrode terminal of the circuit board. An adhesive sheet of a thermosetting resin, a thermoplastic resin, or a mixed thermosetting and thermoplastic resin may be disposed on the circuit board where the bump breaks through the sheet to contact the paste.
