New method monitors semiconductor etching as it happens—with light September 28, 2012 by Liz Ahlberg Enlarge This is a three-dimensional image of the University of Illinois logo etched into a gallium-arsenide semiconductor, taken during etching with a new microscopy technique that monitors the etching process on the nanometer scale. The height difference between the orange and purple regions is approximately 250 nanometers. Credit: Chris Edwards, Amir Arbabi, Gabriel Popescu, and Lynford Goddard (Phys.org)—University of Illinois researchers have a new low-cost method to carve delicate features onto semiconductor wafers using light – and watch as it happens.
