    Abstract: A method according to embodiments of the invention includes growing on a first surface of a sapphire substrate a semiconductor structure including a light emitting layer disposed between an n-type region and a p-type region. The semiconductor structure is formed into a plurality of LEDs. Cracks are formed in the sapphire substrate.
