  • Method for producing a plurality of optoelectronic semiconductor chips
    Patent number: 8916403
    Abstract: A method for producing a plurality of optoelectronic semiconductor chips includes providing a carrier wafer having a first surface and a second surface opposite the first surface, wherein a plurality of individual component layer sequences spaced apart from one another in a lateral direction are applied on the first surface, the component layer sequences being separated from one another by separation trenches; introducing at least one crystal imperfection in at least one region of the carrier wafer which at least partly overlaps a separation trench in a vertical direction; singulating the carrier wafer along the at least one crystal imperfection into individual semiconductor chips.
    Type: Grant
    Filed: February 3, 2011
    Date of Patent: December 23, 2014
    Assignee: OSRAM Opto Semiconductors GmbH
    Inventors: Ewald K. M. Günther, Mathias Kämpf, Jens Dennemarck, Nikolaus Gmeinwieser
