  • Patent number: 11422393
    Abstract: An electro-optic device comprises a first substrate having a first surface, a second surface, and an outer perimeter edge; a second substrate having a third surface, a fourth surface, and an outer perimeter edge, the third surface of the second substrate being opposed to the second surface of the first substrate; a chamber defined between the second surface of the first substrate and the opposed third surface of the second substrate; a first electrode coating disposed on the second surface of the first substrate; a second electrode coating disposed on the third surface of the second substrate; a first conductive or semi-conductive material disposed on and extending longitudinally along at least a portion of a peripheral area of the first substrate and in electrical communication with the first electrode coating; and a non-conductive material extending between the first conductive or semi-conductive material and the second electrode coating.

  • Patent number: 9878400
    Abstract: A laser system is configured to form laser-induced channels in a substrate at a plurality of spaced apart locations along a process path. The laser system includes a laser delivery assembly that receives the laser beam along a receiving axis and directs the laser beam toward the substrate along an impingement axis that forms an oblique angle with a surface of the substrate. The substrate can be divided into separate first and second portions along a separation surface having a draft angle, thereby facilitating substrate division with a zero-kerf process.

  • Patent number: 9808888
    Abstract: A laser system includes a laser configured to emit pulse bursts and a motion device in optical communication with the laser. The motion device moves a laser beam along a process path on a substrate and is configured to have a natural frequency that is greater than an operating frequency of the laser system. The laser system enables high and constant speed processing along tight radii in the process path, which is useful to form laser induced channels along the process path with equal spacing.
