Abstract:
A method of producing prepackaged integrated circuit devices comprising the steps of:providing a wafer having a first surface and a second surface generally parallel to and oppositely directed with respect to said first surface;producing a plurality of integrated circuit dies on said first surface of said wafer, each of the integrated circuit dies comprising a multiplicity of pads;attaching a first electrically insulative plate to said plurality of integrated circuit dies on the first surface of said wafer;attaching a second insulative plate to said second surface of said wafer, at least one of said insulative plates being transparent to radiation in an optical or infra-red spectral range;separating the integrated circuit dies from each other so as to define edges thereof while the dies remain attached to the insulative plates;generally surrounding said integrated circuits on said edges and said second surface with a protective sealant; andthereafter slicing the wafer and protective sealant and the insulative plates attached thereto, thereby to define a plurality of prepackaged integrated circuit devices.
