PURPOSE:To match the connection of a lead easily aligned, and to insert a semiconductor pellet accurately by removing frame hangers at four corners from the side inner than a square surrounded by the four corners of a supporting frame when the pellet is cut from a tape and inserted into a cavity in a case. CONSTITUTION:The frame hangers at four corners are punched by means of a punch according to a tape carrier system. Even when the hangers are punched at that time, the semiconductor pellet 3 does not slip off because the supporting frame 7 and the pellet are connected to the tape 1 by the lead 5. Accordingly, escapes 15 are formed at the four corners of the supporting frame 7. The semiconductor pellet 3 is cut, and incorporated into the case 9. The whole supporting frame 7 is encased into the cavity 10, and a terminal of the lead 5 and an internal terminal 13 contact. Consequently, connection is easily aligned, and the displacement of contact is prevented. |
