  • Patent number: 11817326
    Abstract: Panel level packaging (PLP) with high positional accuracy of dies. The PLP bonds dies accurately to die bonding regions of an alignment panel. High accuracy is achieved by providing die bonding regions with local alignment marks. Accurate die bonding on the alignment carrier results in a reconstructed wafer with accurate positioning of dies. The dies of the reconstructed wafer can be scanned by a die location check (DLC) scan based on sub-blocks of dies, enabling high DLC throughput. The DLC scan generates a DLC file with coordinate points of sub-blocks of the reconstructed wafer. Also, a laser direct imaging (LDI) file can be generated using sub-block circuit files aligned to the DLC file. The use of sub-block circuit files facilitates high throughput in generating the LDI file with high accuracy due to the reconstructed wafer being formed using the alignment carrier with local alignment marks.

  • Patent number: 11772201
    Abstract: A method for producing microcracks in an interior of a composite structure includes: providing or producing the composite structure which has a solid body and at least one metallic coating and/or electrical components situated or provided on one side of the solid body, the solid body containing or being made of silicon carbide (SiC); and producing modifications in the interior of the solid body. Laser radiation is introduced into a flat surface of the solid body to cause multiphoton excitation which brings about plasma generation. The modifications are effected by the plasma in the form of a material transformation which generates compressive stresses in the solid body, thereby developing subcritical cracks in a surrounding area of a particular modification. The laser radiation is introduced into the solid body in pulses having an intensity which reaches a maximum within 10 ns after a start of a particular pulse.

  • Patent number: 11752569
    Abstract: In a method for severing a solid body, a defined contour is stored in a control unit configured to detect contour breaches and to avoid contour breaches. A high-energy beam is moved along a contour on a surface of the solid body, with the surface of the solid body facing the high-energy beam, to produce with the high-energy beam a cutting gap. The contour on the surface is compared with the defined contour stored in the control unit, and avoidance of the contour breach is automatically deactivated when the contour on the surface of the solid body matches the defined contour and a contour breach is detected. Otherwise, the contour is omitted. Advantageously, the high-energy beam travels along the contour with an averaged line movement.

  • Patent number: 10940561
    Abstract: A removably attached coupling assembly can be used to be attached to a laser focus optic assembly of a liquid jet guided laser system. The coupling assembly can include a coupling body, a window assembly, and a nozzle assembly. The coupling assembly thus can allow the independent and separate servicing of the window and the nozzle. For example, to service the window, the coupling assembly can be first detached from the laser focus optic assembly, exposing the top portion of the coupling assembly. The window assembly then can be detached from the coupling assembly. The window can be removed from the window assembly for servicing, such as being repaired or replaced.
