PURPOSE:To enable the screening of an oxide film of a capacitor portion to be performed, by applying a voltage to an outer lead and a lead frame with a tab hanging lead of a semiconductor linked to the lead frame without having adverse effect on other circuits in the semiconductor. CONSTITUTION:A tab hanging lead 11 supports a tab 13. Power source terminals VCC and VSS of a memory cell are connected to any of outer leads 10. Under such a condition, a negative voltage is applied to a lead frame 9 and 0 volt is applied to the outer lead 10 connected to the terminals VCC and VSS. With such an arrangement, a plurality of semiconductors connected to the frame 9 can be screened simultaneously. After the completion of the screening, an ordinary resin sealed type semiconductor can be obtained by cutting off the tab hanging lead 11 along a resin 12.
