  • Trenches for increasing a quantity of reliable chips produced from a wafer
    Patent number: 10784354
    Abstract: A light-emitting device may comprise a set of layers comprising a substrate layer, and a set of epitaxial layers deposited on the substrate layer. The set of epitaxial layers may include a strained layer. The strained layer may include a set of active zones to be used to generate optical gain. The light-emitting device may comprise a set of trenches etched into a subset of the set of layers of the light-emitting device. The set of trenches may prevent a set of defects or dislocations in a wafer from which the light-emitting device was formed from propagating into the set of active zones.
    Type: Grant
