Abstract

PURPOSE:To prevent the short-circuit generating when a large-sized thick chip is connected by a method wherein the bonding section of the outer take out lead on a lead frame is formed at the same level as the pad section of the chip by upheaving the bonding section. CONSTITUTION:The bonding section 13a of the outer lead 13 on the lead frame 10 is upheaved in reversed L-shape and formed almost at the same height as the pad section of the chip 11a which was fixed on the bed 12. The height is established in proportion to the thickness of the chip 11 and when a bonding work is performed after the chip has been fixed, the wire 14 should be connected without loosening. Through these procedures, the short-circuit between the wire 14 and the chip 11 can be prevented, thereby enabling to improve the reliability of the device.
