Abstract
A method according to embodiments of the invention includes providing a light emitting semiconductor structure grown on a substrate. The substrate has a front side and a back side opposite the front side. Notches are formed in the substrate. The notches extend from the front side of the substrate into the substrate. After forming notches in the substrate, the back side of the substrate is thinned to expose the notches.
