Abstract
Systems, apparatuses, and methods related to the design, fabrication, and manufacture of gallium arsenide (GaAs) integrated circuits are disclosed. Copper can be used as the contact material for a GaAs integrated circuit. Metallization of the wafer and through-wafer vias can be achieved through copper plating processes disclosed herein. Direct die solder (DDS) attach can be achieved by use of electroless nickel plating of the copper contact layer followed by a palladium flash. GaAs integrated circuits can be singulated, packaged, and incorporated into various electronic devices.
