Abstract
A method according to embodiments of the invention includes providing a wafer comprising a semiconductor structure grown on a growth substrate. The semiconductor structure includes a light emitting layer disposed between an n-type region and a p-type region. The wafer includes trenches defining individual semiconductor devices. The trenches extend through an entire thickness of the semiconductor structure to reveal the growth substrate. The method further includes forming a thick conductive layer on the semiconductor structure. The thick conductive layer is configured to support the semiconductor structure when the growth substrate is removed. The method further includes removing the growth substrate.
