Abstract: A substrate comprises glass, sapphire, silicon and/or aluminosilicate, and has at least one recess or through-opening. The at least one recess or through-opening is formed by anisotropic removal of substrate material by etching a portion of the substrate that has been modified by a pulse of laser radiation in a direction of a thickness of the substrate. The modified portion of the substrate extends along a beam axis of the laser radiation. The pulse of laser radiation was applied with a focus extending from a first focal depth positioned past one side of the substrate to a second focal depth located at an opposite side of the substrate.

Abstract: A device for modifying a region of a substrate includes a laser radiation source for pulsed laser radiation. A transmissive medium having a higher intensity-dependent refraction index than air is arranged between a laser machining head and the substrate such that an individual pulse of the pulsed laser radiation from the laser machining head is deflected through the transmissive medium and across a thickness of the substrate from an original focal depth to a focal depth different from the original focal depth to modify the substrate along a beam axis of the laser radiation in a region of a recess or through-opening to be formed in the substrate without removing an amount of the substrate material necessary to form the recess or through-opening. A length between the focal depths is greater than and extends across the thickness of the substrate.

Abstract: A device for modifying a region of a substrate includes a laser radiation source for pulsed laser radiation. A transmissive medium having a higher intensity-dependent refraction index than air is arranged between a laser machining head and the substrate such that an individual pulse of the pulsed laser radiation from the laser machining head is deflected through the transmissive medium and across a thickness of the substrate from an original focal depth to a focal depth different from the original focal depth to modify the substrate along a beam axis of the laser radiation in a region of a recess or through-opening to be formed in the substrate without removing an amount of the substrate material necessary to form the recess or through-opening. A length between the focal depths is greater than and extends across the thickness of the substrate.

Abstract: A method for producing a recess or through-opening in a substrate includes applying pulsed laser radiation to the substrate. The laser radiation is focused using an optical system at an original focal depth and, by non-linear self-focusing within the pulse duration of an individual pulse, is also focused by the optical system at a focal depth different from the original focal depth. A difference between the focal depths corresponds to or is greater than the longitudinal extent of the recess or though-opening to be produced. The laser radiation modifies the substrate along a beam axis of the laser radiation in the region of the recess or through-opening, but does not result in removal of the substrate material necessary to form the recess or the through-opening. The substrate material in the modified region is anisotropically removed to produce the recess or through-opening in the substrate.

Abstract: A method and device for separating a substrate with a laser beam. The duration of the laser beam's effect is extremely short, so the substrate is only modified concentrically about the laser beam axis (Z) without it degrading the substrate material. While the laser beam acts upon the substrate, the substrate moves relative to a laser machining head, producing plural filament-type modifications along a separating surface to be incorporated. The laser beam is initially diverted by a transmission medium having a higher intensity dependent refractive index than air, then reaches the substrate. The non-constant pulsed laser intensity increases to a maximum over the temporal course of the single pulse, then reduces, and the refractive index changes. The laser beam focus point moves between the substrate's outer surfaces along the beam axis (Z), reaching the desired modification along the beam axis (Z) without correcting the laser machining head in the z-axis.

Abstract: A method and device can create, with a laser beam, plural recesses in a substrate useful as an interposer, and a substrate produced thereby. A laser beam may be directed to the surface of a substrate. The duration of the laser beam effect is extremely short such that the substrate is only modified concentrically about the laser beam axis without reaching a substrate material recess. The laser beam is initially diverted by a transmission medium having a higher intensity-dependent refractive index than air, and subsequently reaching the substrate. Non-constant pulsed laser intensity increases to a maximum over the temporal course of the single pulse, then reduces; the refractive index also changes. The focus point of the laser beam moves between the outer surfaces of the substrate along the beam axis such that it reaches the desired modification along the beam axis without correcting the laser processing head in the z-axis.

Abstract: A method for producing an electrically conductive structure, e.g., a conducting track, on a non-conductive substrate material, having an additive (1) having at least one metal compound. The substrate material may be irradiated using a laser to selectively activate the metal compounds, for example inorganic metal compounds, contained in the additive (1). The metal seeds formed by the activation are then metallized to create the electrically conductive structure on the substrate material. Because the additive (1) has a preferably full-surface coating before the additive is introduced into the substrate material, such that the additive (1) is reduced and the coating is oxidized by the laser activation, the reaction partners necessary for the required chemical reaction with the additive (1) are provided by the coating. Because of the thereby significantly reduced interaction with the substrate material, the limitation to certain plastics or plastic groups also is lifted.
