Abstract:
A method includes providing a semiconductor wafer that includes at least one optical waveguide extending in a longitudinal direction. Stealth dicing laser processing is applied to the semiconductor wafer by producing defect regions into the wafer along at least one cutting line. The cutting line is oblique to the longitudinal direction of the at least one optical waveguide. The wafer is expanded to induce fracture thereof at the at least one cutting line, thereby producing an end surface of the at least one optical waveguide. The end surface is oblique to the longitudinal direction of the at least one optical waveguide.

Claim (Index 3):
The method of  claim 1 , wherein applying stealth dicing laser processing comprises adjusting a power intensity or a number of laser passes of stealth dicing laser processing to provide optical quality of the end surface of the optical waveguide.
