The gallium arsenide (GaAs) circuits in advanced communication application have been considered to profoundly supersede the conventional silicon-based counterpart. Great improvements in the packaging of GaAs devices are needed to overcome the imminent handicap of its fragile characteristic; Thin die represents the mainstream for IC packages to achieve the goal of manufacturing compact and light products with higher functionality. These trends tend to challenge the existing infrastructure, henceforth; the creative design in connection with a unique die bonder in fabrication has been presented...
