Abstract

The Nd:YAG laser is now being employed in a number of cost effective applications in semiconductor manufacture. Three of these are briefly reviewed: (1) the use of the CW-pumped, repetitively Q-switched Nd:YAG laser for dicing of circular die for power devices, (2) the application of a small, passively Q-switched, pulse-pumped Nd:YAG laser for repair of defects in hard-surface photomasks and (3) the use of a CW-pumped, Nd:YAG laser with internal second-harmonic-generator, for direct diffusion of dopants to produce back-side ohmic contacts.
