High temperature circuit apparatus

Abstract

A method for interconnecting high-temperature silicon carbide (SiC) devices enables such high-temperature devices to be used in fabricating electronic circuits of significant scale. This method comprises empirically measuring operational characteristics of a plurality of the devices to be interconnected, the operational characteristics comprising devices which are measured to be non-working and devices which are measured to be working; characterizing the operational characteristics in an operational characteristics map; designing interconnection paths between and among the devices that are characterized to be working by the operational characteristics map; and excluding from the interconnection paths, devices that are characterized to be non-working by the operational characteristics map. A preferred embodiment of this method further includes disposing a temporary polymer layer over the devices; forming via holes through the temporary polymer layer, to bonding pads of the devices; applying a current-balancing resistive metal over the temporary polymer layer; establishing connections between the current-balancing resistive metal and the bonding pads; designing the interconnection paths between and among the working devices by patterning the current-balancing resistive metal based on the operational characteristics map; and removing the temporary polymer layer.
