Patent ID: 7566575

Claim:
A method for producing a semiconductor-chip-mounting circuit, the method comprising: a step A of forming a contact on a surface of a connecting terminal disposed on a mounting circuit, the contact being composed of solder and being in the form of a conical helix or a polygonal pyramidal helix; a step B of pressing a bump disposed on a semiconductor chip against the contact; after pressing the bump against the contact, a step C of applying a test voltage to an interconnection pattern formed in the mounting circuit so as to perform a continuity test for the semiconductor chip and the mounting circuit; when the continuity test in the step C demonstrates that the semiconductor chip or the mounting circuit operates abnormally, a step D of replacing the semiconductor chip or the mounting circuit with new one and either performing the step B and the subsequent steps when the semiconductor chip is replaced or performing the step A and the subsequent steps when the mounting circuit is replaced; and only when the continuity test in the step C demonstrates that the semiconductor chip and the mounting circuit operate normally, a step E of melting the contact so as to bond the bump to the connecting terminal.
