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.

Abstract:
A multilayer circuit includes a dielectric base substrate, conductors formed on the base substrate and a vacuum deposited dielectric thin film formed over the conductors and the base substrate. The vacuum deposited dielectric thin film is patterned using sacrificial structures formed by electroplating techniques. Substrates formed in this manner enable significant increases in circuit pattern miniaturization, circuit pattern reliability, interconnect density and significant reduction of over-all substrate thickness.
