  • Method of fabricating optical devices using laser treatment of contact regions of gallium and nitrogen containing material
    Patent number: 8975615
    Abstract: A method for forming optical devices includes providing a gallium nitride substrate having a crystalline surface region and a backside region. The backside is subjected to a laser scribing process to form scribe regions. Metal contacts overly the scribe regions.

  • Singulation method and resulting device of thick gallium and nitrogen containing substrates
    Patent number: 8313964
    Abstract: A method for singulation of thick GaN wafers (e.g., 300-400 um) through the use of a double-side laser-scribe process. In a preferred embodiment, the patterned GaN substrate is processed using a laser-scribe on each side of the substrate to form scribe lines. The scribe lines are aligned to each other. In a preferred embodiment, the substrate has not been subjected to a thinning or polishing process for reducing its thickness.
