A multilayer circuit substrate for multi-chip modules or hybrid circuits 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 shadow mask techniques. Substrates formed in this manner enable significant increases in interconnect density and significant reduction of over-all substrate thickness.
