摘要:
The invention relates to a method and a device for generating a jet of liquid which is suitable, in the manner of a waveguide, to carry a laser beam injected into it and which is used to process a work piece. Said device comprises a liquid nozzle for generating a jet of liquid and a gas outlet nozzle, disposed at a distance from the liquid nozzle and producing a flow of gas enclosing the jet of liquid on the exterior thereof. A gas storage is defined between the liquid nozzle and the gas outlet nozzle. The jet of liquid is passed or ejected through the gas outlet nozzle. The jet of liquid has a diameter of preferably 60 m or less and the flow of gas has a diameter of 1-2 mm.

The invention relates to a device (1) for cutting wafers (2) into a number of chips with a laser beam (6) injected into a liquid jet (7). A thin flowing liquid layer (9) having a blasting effect is produced on the surface (5) of the wafer (2). This makes it possible to prevent projections resulting during laser cutting from depositing once again on the surface of the wafer. The result is a very high cleanness of the surface after the cutting process. The liquid layer (9) is produced, in particular, so that it is thinner in a machining area (10) around the machining point (8) than outside of the machining area (10). This ensures that the liquid layer is sufficiently thin (14) at the machining point (8) so that enough laser energy for removing material is applied to the wafer surface, and ensures that the liquid layer is sufficiently thick (15) outside of the machining area so that no area of the surface (5) of the wafer (2) dries out.
