Latest Patents

Garrit Ubink holds a patent for a "Method and apparatus for scribing a substantially planar semiconductor substrate with on-the-fly control of scribing alignment." This invention involves a method of scribing a substrate along a scribeline by utilizing a laser beam. The laser beam impinges on the major surface of the substrate, creating a light spot that is positioned proximal to the scribeline. The substrate and laser beam are moved relative to one another, allowing the light spot to translate along the scribeline. This process enables localized energy transfer from the laser beam to the substrate, ensuring precise scribing. The positioning of the light spot is monitored through imaging techniques, and image recognition software is employed to analyze the images for momentary position information, which is crucial for regulating the laser beam's position.
