Abstract:
1. A method for manufacturing a laser diode device from a plurality of gallium and nitrogen containing semiconductor substrates, each of the gallium and nitrogen containing semiconductor substrates (“substrates”) having a plurality of epitaxially grown layers overlaying a top-side of each of the substrates, the method comprising: determining an orientation of a reference crystal direction for each of the substrates; aligning at least one of the substrates to a spatial region configured in a selected direction of a first handle substrate, the first handle substrate having a larger spatial region than a sum of a total backside region of plurality of the substrates to be arranged in a tiled configuration overlying the first handle substrate, such that the reference crystal direction for the substrate is parallel to the spatial region in the selected direction within 10 degrees or less; mating a backside region of the substrate, which has been aligned, to a portion of a surface region of the first handle substrate; bonding the substrate to portion of the surface region of the first handle substrate using a first bonding medium provided between the first handle substrate and the substrate while maintaining the alignment between reference crystal orientation and the selected direction of the first handle substrate; repeating the aligning, mating, and bonding for all of the other plurality of substrates to form an array of substrates spatially disposed on the surface region of the first handle substrate in the tiled arrangement; and thereafter processing each of the substrates, concurrently, by forming metal contacts and/or forming metal bond pads to the p-type and/or n-type gallium and nitrogen containing layers.
