Kind Code:
A1
Abstract:
According to an embodiment of the present invention, in a semiconductor device manufacturing method, a lead frame is prepared, said lead frame having formed therein a groove section such that the lower surfaces of a first lead and a second lead, which are connected between device regions adjacent to each other, are communicated with each other. After a part of a connecting section between the first and second leads is cut using a first blade, metal waste formed in the groove section is removed. After removing the metal waste, a metal film is formed on exposed surfaces of the first and second leads by means of a plating method, then, the remaining part of the connecting section of the first and second leads is cut using a second blade. At that time, cutting is performed such that the second blade is not brought into contact with the groove section.
