ABSTRACT:
A method of using a semiconductor device having a plurality of external contact terminals formed of springy wires, usable in a stable state free from variation of contact voltage for a long period even if a contact terminal repeatedly makes contact several hundreds or thousands of times. A tip end of the external contact terminal is plated with individually, selectively removable multiple films, and the plated films are individually, selectively removed by an etching treatment, in accordance with the degree of contamination of the tip end of the external contact terminal, and then the external contact terminal is rinsed and rendered reusable.
