  • Patent number: 11377387
    Abstract: A method for producing microstructures includes introducing modifications by a laser beam into a volume between two opposite outer surfaces of a glass substrate. An etching method is carried out which provides anisotropic material removal in one of the outer surfaces so as to produce recesses that have a conical shape. A layer that is resistant to an etching effect of the etching method is applied as a cover layer to only one outer surface. Then, a further etching method is carried out so that material is removed in the other outer surface until recesses of this other outer surface, which are produced and/or enlarged by the further etching method, have reached the cover layer.

  • Patent number: 11358188
    Abstract: Systems and methods for rinsing beverage residue from a mechanical interface between threads of a bottle and threads of a bottle cap is described. The bottle cap may include a sealable coating to create a seal against a rim of the bottle. The bottle cap may also include passages to allow pressurized water to be injected into an upper inner region of the bottle cap. The pressurized water is prevented from entering the bottle due to the seal between the rim of the bottle and the sealable coating of the bottle cap. Therefore, the pressurized water is caused to escape through the mechanical thread interface toward a lower inner region of the bottle cap where the water escapes from the cap at atmospheric pressure.

  • Patent number: 11361947
    Abstract: In an apparatus for plasma processing according to an exemplary embodiment, a radio frequency power source generates radio frequency power which is supplied for generation of a plasma. A bias power source supplies bias power to a lower electrode of a substrate support. The bias power varies a potential of a substrate within a cycle thereof. The radio frequency power is supplied in at least a part of a first period in the cycle, in which the potential of the substrate is relatively high. A power level of the radio frequency power is lowered in a second period in the cycle, in which the potential of the substrate is relatively low. In the first period and the second period, the sheath adjuster adjusts a position in a vertical direction of an upper end of a sheath above an edge ring.

  • Patent number: 11344973
    Abstract: Methods for forming holes in a substrate by reducing back reflections of a quasi-non-diffracting beam into the substrate are described herein. In some embodiments, a method of processing a substrate having a first surface and a second surface includes applying an exit material to the second surface of the substrate, wherein a difference between a refractive index of the exit material and a refractive index of the substrate is 0.4 or less, and focusing a pulsed laser beam into a quasi-non-diffracting beam directed into the substrate such that the quasi-non-diffracting beam enters the substrate through the first surface. The substrate is transparent to at least one wavelength of the pulsed laser beam. The quasi-non-diffracting beam generates an induced absorption within the substrate that produces a damage track within the substrate.
