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 2):
The method for manufacturing a semiconductor package according to  claim 1 , wherein the Cu alloy is a first Cu alloy, the joining material is a first joining material, the intermetallic compound is a first intermetallic compound, and the lead frame includes a mount portion comprising a second Cu alloy, the method further comprising:\n applying a second joining material including Sn or a Sn alloy on the mount portion; mounting an electronic component on the second joining material; and heating the mount portion while applying a pressure to the electronic component so as to react the Sn or the Sn alloy in the second joining material and the second Cu alloy of the mount portion so as to produce a second intermetallic compound.
