ABSTRACT:
A semiconductor device card and a method of manufacturing the card. A frame includes an integral spacer which fills a dead space on a circuit board to eliminate the need for positioning a separate spacer in the dead space on the circuit board and fixing the spacer in place with a bonding sheet or the like. In a semiconductor device card in which a spacer for filling a dead space on the circuit board is bonded to a corresponding panel, a recess is formed on the surface of the spacer bonded to the obverse or reverse panel to reduce undulations occurring in the panel surface.
