Abstract:
RIE with natura1 lithography has two advantages over RIE with automasking:the process causes less surface damage and the process window is broader. We have systematically explored the parameter range of our process and identified a natura1 lithography RIE process which causes a minimum amount of surface damage. By using this RIE process and a wet chemical etch of a few nanometers, we reached a gain in shortcircuit current of 2.9% and no loss in open circuit voltage. This resulted in an absolute efficiency gain of 0.6% for the RIE textured wafers.
