Abstract
Two different lasers were used to etch patterns on Si surfaces employing a thin film cell configuration. A strong, pulsed, 20 W KrF excimer laser was used for etching. A weak, CW, 5 mW HeNe laser was serving as background light which by itself was incapable to etch the Si surface. A substantial enhancement of the laser etching process with light background was observed. Etching process using many pulses was compared to etching by use of only one laser pulse.
