Abstract:
A base substrate, high-k substrate layers on the base substrate with discrete decoupling capacitors embedded, high density substrate layers on the high-k substrate layers supporting wiring and wiring spacing of less than 2 up to about 10 micron width, pitch connectivity between the upper surface of the base substrate and a lower surface of the set of high density substrate layers supports less than 50 up to about 300 micron pitch, the pitch connectivity on an upper surface of the set of high density substrate layers supports less than about 150 micron pitch. A method including attaching a set of metal posts at each contact on a lower surface of a set of high density substrate layers, attaching to a handler, attaching an interconnect layer to a base substrate, and attaching the set of high density substrate layers to the base substrate while aligning each metal post with a contact.
