Abstract

A semiconductor is cut by directing a green laser beam of high power, and subsequently directing a UV beam along the cut line. The first beam performs cutting with relatively rough edges and a high material removal rate, and the second beam completes the cut at the edges for the required finish, with a lower material quantity removal.
