Abstract
A method of making a circuitized substrate wherein a chip-accommodating cavity is formed along with a plurality of conductive elements (e.g., pads, lines, etc.) which form part of the substrate's circuitry. Metallization is facilitated by the use of a photoimageable member that allows for initial removal (peeling) of its sacrificial layer, followed by eventual removal of the photoimaging layer which also forms part of this member. Exposure of the photoimaging layer may occur either through the protective sacrificial layer or subsequent removal thereof.
