PURPOSE:To eliminate the need for removing a driver after a transfer-molding by enclosing a space between leads with a bridging member when a molding die is applied to a lead frame. CONSTITUTION:There is provided a bridging section 14 which is fixedly bonded between leads 8 located at a boarder 13 equivalent to the outer surface of sealing resin 9 and extends between the leads 8 and which is as thick as the leads 8. The bridging section 14 couples the leads respectively and maintains their positions. When a molding die is applied to a lead frame for transfer molding and the leads 8 are clamped with the die, the following roles are fulfilled: More specifically, a space 7 between the leads 8 is enclosed with the bridging component 14 and the sealing resin injected from a molding cavity of the molding die is arranged to pass through the space 7, thereby preventing leakage out. It is, therefore, possible to eliminate the need for removing a diver after a transfer-molding. |
