Abstract

1375054 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Feb 1972 [5 Feb 1971] 4893/72 Heading H1K A semi-conductor wafer provided with contact pads is face bonded to a flexible plastics, e.g. polyimide foil with its pads engaging the inner ends of conductive tracks on the foil. The foil is in turn face-bonded to an insulating support plate, e.g. of hard paper or ceramic, with the outer ends of its track engaging the inner ends of a corresponding pattern of tracks on one face of the plate which extend outwards to electrically contact current supply pins extending through the plate and projecting from said one face. To accommodate the wafer without stretching the foil the plate may have a central aperture. This may subsequently be sealed up with resin but where cooling is important a cooling member is stuck to the back face of the plate and has a projection engaging the wafer in the aperture. Though it may be flat the member is preferably U-shaped, with its legs extending in the same direction as the pins to stand the device off from a printed circuit into which it is pinned, or in the opposite direction in which case sections of the legs may be bent inwards to clamp on a finned extruded aluminium cooling element. The cooling member may be secured to the plate by dimpling its legs beyond the plate or by providing it with integral hollow rivets passing through holes in the plate or with a lug which may be bent round the edge of the plate. Such a lug may also provide electrical connection to any of the tracks on the plate or foil, a function which may alternatively be performed by a track extending on the back face of the plate from one of the pins. The wafer is passivated with glass or with a solvent free mixture of amino-alkyl silane and epoxy resin which is drawn into the gap between it and the foil by capillary action and then cured. Methods of forming the tracks on the foil are described.
