Classification: CPC B | IPC B

Claim 7:
8. A process of producing optical devices, comprising:
transferring a filamented substrate from a filamentation stage to a singulation stage of a laser dicing tool, the filamented substrate comprising a first plurality of optical devices that are each filamented along a contour surrounding regions of first device structures, the filamented substrate is disposed in the singulation stage with projections of the singulation stage contacting portions of the first plurality of optical devices between the regions of the first device structures;
transferring a second substrate comprising a second plurality of optical devices to the filamentation stage, each optical device of the second plurality of optical devices of the second substrate having a contour surrounding regions of second device structures, the second substrate is disposed in the filamentation stage with projections of the filamentation stage contacting portions of the second plurality of optical devices between the regions of the second device structures; and
conducting a filamentation process on the second substrate while conducting a separation process on the filamented substrate, the filamentation process comprising filamenting each of the second plurality of optical devices of the second substrate along the contour surrounding the regions of the second device structures, and the separation process comprising separating each of the first plurality of optical devices of the filamented substrate along the surrounding regions of the first device structures.
