Abstract:
A method for interconnecting high-temperature silicon carbide (SiC) devices on a substrate, comprising:empirically measuring operational characteristics of the devices; characterizing operational characteristics of the devices in an operational characteristics map, the operational characteristics map including identification of non-working devices and working devices; using the operational characteristics map to design interconnection paths for interconnecting the working devices and excluding the non-working devices; 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 in accordance with the designed interconnection paths; establishing via connections between the current-balancing resistive metal and the bonding pads; applying a high-temperature shunt metal over the current-balancing resistive metal in accordance with the designed interconnection paths; removing selected portions of the shunt metal to create notches in the shunt metal for altering electrical resistances in accordance with the designed interconnection paths; and removing the temporary polymer layer.
