Abstract:
A semiconductor wafer having at least one semiconductor device formed thereon, said wafer comprising:a semiconductor wafer substrate having a first side, a second side and a plurality of street areas thereon forming areas on the semiconductor wafer substrate within which a semiconductor device is located, the semiconductor wafer substrate having portions thereof removed through the thickness thereof in the plurality of street areas thereof;at least one semiconductor device formed on the first side of the semiconductor wafer substrate, the at least one semiconductor device having a periphery having a street area extending therefrom over a portion of the semiconductor wafer substrate, the at least one semiconductor device having a plurality of bond pads formed thereon, the at least one semiconductor device formed on the semiconductor wafer substrate having portions of the substrate removed from the street areas of the semiconductor wafer substrate, the at least one semiconductor device having the periphery thereof formed by the portions of the semiconductor wafer substrate removed in the plurality of street areas;a first coating covering the first side of the semiconductor wafer substrate and the at least one semiconductor device formed on the first side of the semiconductor wafer substrate, the first coating sealingly engaging the first side of the semiconductor wafer substrate, the first coating on the first side of the semiconductor wafer substrate covering the at least one semiconductor device formed thereon without sealingly engaging the plurality of bond pads formed thereon;a second coating covering the second side of the semiconductor wafer substrate substantially filling the portions of the street areas of the semiconductor wafer substrate which have been removed, thereby separating areas of the semiconductor wafer substrate from other areas thereof, the second coating contacting the first coating in the portions of the street areas of the semiconductor wafer substrate which have been removed, the second coating substantially hermetically sealingly engaging the periphery of the at least one semiconductor device; andat least one metal circuit being connected to at least one bond pad of the plurality of bond pads of the at least one semiconductor device, the at least one metal circuit extending to a location adjacent the periphery of the at least one semiconductor device, the at least one metal circuit sealingly engaging the first coating on the semiconductor wafer substrate and the at least one bond pad of the plurality of bond pads of the at least one semiconductor device.
