Abstract

1509142 Semiconductor devices AMP Inc 31 March 1976 [18 Nov 1975] 12911/76 Heading H1K A plurality of convergent metal fingers 16, the inner ends of which define an area in or over which a semiconductor chip is to be received with its contacts connected to the fingers 16, is bonded to an insulating support sheet 10, at least some of the support sheet 10 having been removed both from the chip receiving area and from the outer ends of the fingers, but the fingers 16 remaining supported by the sheet 10 throughout their lengths. The arrangement allows for differential thermal expansion between the sheet 10 and fingers 16 while maintaining adequate support for the latter. A plurality of such arrays of fingers may be provided on a common support sheet.
