Abstract

PURPOSE:To enable the manufacturing process to be performed in high yield without increasing the numbers of processes by a method wherein the active surfaces of semiconductor pellets connected to tape leads as well as the tape leads themselves are respectively bonded to one another rear to rear using an insulating bonding agent. CONSTITUTION:Tape leads 1 gang-bonded to semiconductor elements 4 as well as the active surfaces of the semiconductor elements 4 are respectively bonded to one another rear to rear using an insulating bonding agent 3 so that the gangbonding may suffice for the connection between the semiconductor elements 4 and the tape leads 1 to eliminate the bonding by face-down process. Furthermore, the active surfaces of the elements 4 can be sufficiently filled up with a molding agent 6 in the molding process by bonding the active surfaces of the semiconductor elements 4 rear to rear. Through these procedures, the manufacturing yield can be augmented while performing the high density mounting process capable of maintaining the reliability such as moisture resistance, etc.
