Abstract
A baseboard for orthogonal mounting of integrated circuit chips thereto is described. Plural channels (14) are anisotropically etched in a silicon baseboard (10). A corresponding plurality of integrated circuit chips (12) are inserted into the channels (14). A number of baseboard contact pads (18) are formed adjacent each channel (14), and are solder bonded to corresponding chip conductor pads (16). Interconnect conductors (20, 28) provide connection of each baseboard pad (18) either to other chips (12) or to connector pads (22) located adjacent an edge (26) of the baseboard chip mount (10). A coating (30) of silicon carbide over the surface of the baseboard chip mount (10) improves the thermal efficiency of the assembly.
