Abstract
A detailed study of the important role of temperature and gas ambient on the bonding between Si and InGaAs wafers was performed. The heteroi nterface was characterized by fabricating p-i-n photodetectors and mea suring the forward and reverse currents, the capacitance, the absolute quantum efficiency, and the response bandwidth. Clear evidence for a thin tunneling barrier is found for nonoptimum fusing conditions. (C) 1997 American Institute of Physics.
