…ferroelectrics and “high k” gate resistors, semiconductor alloys, carbon nano-tubes, and more. Although visible or IR laser beams have been used for PLD applications, UV beams are now most commonly employed. Among UV pulsed lasers, excimer lasers provide a variety of short wavelengths combined with…
