Abstract:
A method for manufacturing a semiconductor package by preparing a lead frame including a to-be-cut portion containing a Cu alloy; applying a joining material including Sn or a Sn alloy to the to-be-cut portion; heating the to-be-cut portion so as to react the Sn or Sn alloy and the Cu alloy so as to form an intermetallic compound having a void therein; and cutting the to-be-cut portion together with the intermetallic compound.

Claim (Index 16):
A method for cutting a Cu alloy, the method comprising:\n applying a joining material including Sn or a Sn alloy to a to-be-cut portion comprising a Cu alloy; heating the to-be-cut portion so as to react the Sn or the Sn alloy and the Cu alloy to produce an intermetallic compound having a void therein; and cutting the to-be-cut portion together with the intermetallic compound.
