Abstract

1522408 Semiconductor devices; connection tapes NATIONAL SEMICONDUCTOR CORP 2 July 1976 [7 July 1975] 27684/76 Headings H1K and HIR In a method of making an interconnecting tape of the type for use in a multi-bonding machine and carrying a row of individual lead patterns 15 for connection to a S.C. die, the lead patterns are formed in a metal tape 11 at regions having an insulating support area 13 and sprocket holes 12, 17<SP>1</SP> are produced in fixed predetermined relation to the patterns for indexing during production and correct positioning in the bonding machine. As shown in Fig. 3, a Cu tape 11 is punched to form marginal sprocket holes 12. The insulating support areas 13, e.g. epoxy or polyimide rings, are screened or injection-moulded on to the tape, which is then cured. An adhesion-promoting coating of chromate anti-oxidant is applied before a standard photo-resist and the side of the tape opposite to the supports 13 is exposed through a mask 16 in register with the holes 12 to produce lead patterns 15 and a further sprocket hole pattern 17 for indexing each individual tape 21 when the tape 11 is sub-divided. The tape is etched forming leads 22 and holes 17<SP>1</SP> and is then sub-divided. The inner end of each lead 22 is bonded to a contact bump (28) (Fig. 8, not shown) on a S.C. die (27) and the outer end is bonded to a lead frame member (29). The lead pattern is sheared along a line 31 so that the die (27) is transferred from the tape 21 to the frame (29).
