Abstract:
A circuitized substrate (11) (e.g., PCB) including an internal optical pathway (33) as part thereof such that the substrate (11) is capable of transmitting and/or receiving both electrical and optical signals. The substrate (11) includes an angular reflector (25) on one of the cladding layers (17) such that optical signals passing through the optical core (33) will impinge on the angled reflecting surfaces (31) of the angular reflector (25) and be reflected up through an opening (55) (including one with optically transparent material (61) therein), e.g., to a second circuitized substrate (73) also having at least one internal optical pathway as part thereof, to thus interconnect the two substrates (11, 73) optically. A method of making the substrate (11) is also provided.
Abstract:
A circuitized substrate (11) comprised of at least one dielectric material (13) having an electrically conductive pattern thereon. At least part of the pattern is used as the first layer of an organic memory device (35) which further includes at least a second dielectric layer over the pattern and a second pattern aligned with respect to the lower part for achieving several points of contact to thus form the device. The substrate (11) is preferably combined with other dielectric-circuit layered assemblies to form a multilayered substrate on which can be positioned discrete electronic components (e.g., a logic chip) coupled to the internal memory device to work in combination therewith. An electrical assembly (71) capable of using the substrate is also provided, as is an information handling system (101) adapted for using one or more such electrical assemblies as part thereof.

The thermal cooling structure (13) is adapted for having cooling fluid pass there-through during operation of the assembly. A method of making the substrate is also provided.
