5 Key elements to look for in your etch process
High wafer throughput Fast etch rates and low clean overheads mean higher tool uptime. Higher uptime means more wafers through your fab Profile control Vertical facets means higher device efficiency – more light out for power in Smooth surfaces Smooth surfaces means less light scattering – more usable light Accurate depth control Essential with such complex structures, stopping in the right layer can make or break your device Uniformity Uniform etch depth means that more devices can be...
