  • Publication number: 20230130979
    Abstract: A semiconductor device includes an active region and a trapping region positioned peripherally with respect to the active region, the trapping region presenting trapping apertures permitting the passage of particles, the trapping apertures being in fluid communication with at least one trapping chamber for trapping the particles. A method for manufacturing the semiconductor devices from one semiconductor wafer presents semiconductor device regions to be singulated along a dicing portion line.

  • Patent number: 10029913
    Abstract: A method of removing a reinforcement ring from a wafer is described. The method includes forming a ring-shaped recess in a first surface of the wafer and separating the reinforcement ring from an inner region of the wafer along the ring-shaped recess.
    Type: Grant

    Assignee: Infineon Technologies AG
    Inventors: Adolf Koller, Bernhard Drummer
  • Patent number: 9911655
    Abstract: A method of dicing a wafer may include forming a plurality of active regions in a wafer, each active region including at least one electronic component, the active regions extending from a first surface of the wafer into the wafer by a height and being separated by separation regions, forming at least one trench in the wafer by plasma etching in at least one separation region from the first surface of the wafer. The at least one trench is extending into the wafer farther than the plurality of active regions. The method may further include processing a remaining portion of the wafer in the separation region to separate the wafer into individual chips.
    Type: Grant

  • Patent number: 9570352
    Abstract: A method of dicing a wafer may include forming a plurality of active regions in a wafer, each active region including at least one electronic component, the active regions extending from a first surface of the wafer into the wafer by a height and being separated by separation regions, the separation regions being free from metal, forming at least one trench in the wafer by plasma etching in at least one separation region from the first surface of the wafer. The at least one trench is extending into the wafer farther than the plurality of active regions. The method may further include processing a remaining portion of the wafer in the separation region to separate the wafer into individual chips.

  • Publication number: 20070170564
    Abstract: A smart card module including a substrate having an upper face and a lower face, contact arrays arranged on the substrate lower face, conductor structures, which have vias arranged in cutouts in the substrate, arranged on the substrate upper face and connected to the contact arrays, a chip having connecting contacts which are electrically conductively connected to the conductor structures, wherein the chip is mounted by a mount on the substrate upper face or on the conductor structures, and an encapsulation, which covers the chip and at least a part of the conductor structures and of the substrate upper face.
