Abstract:
A method of sealing semiconductor devices, said method comprising:providing at least one semiconductor device on a first side of a wafer substrate, the wafer substrate having a first side, a second side, and a thickness, the at least one semiconductor device having a plurality of sides and at least two bond pads thereon;reducing the thickness of at least a portion of the wafer substrate from the second side thereof;coating the first side of the wafer substrate with a first coating to substantially seal the at least one semiconductor device formed on the first side of the wafer substrate;removing a portion of the wafer substrate from each side of the at least one semiconductor device formed on the first side of the wafer substrate, the portion of the wafer substrate being removed extending from the second side of the wafer substrate to the coating on the first side of the wafer substrate;coating the second side of the wafer substrate with a second coating to substantially seal the second side of the wafer substrate and to substantially seal the plurality of sides of the at least one semiconductor device;removing a portion of the first coating on the first side of the wafer substrate to uncover a portion of the at least two bond pads located on the at least one semiconductor device; andapplying a third coating to the at least two bond pads of the at least one semiconductor device, the third coating sealingly engaging the at least two bond pads and the first coating.
