Embodiment Construction
[0047]The preferred embodiments of the present invention will be better understood by those skilled in the art by reference to the above listed figures. The preferred embodiments of this invention illustrated in the figures are not intended to be exhaustive or to limit the invention to the precise form disclosed. The figures are chosen to describe or to best explain the principles of the invention and its applicable and practical use to thereby enable others skilled in the art to best utilize the invention.
[0048]A thick LED semiconductor structure chip is at least 10 microns thick and does not need the original growth substrate or an attached transfer substrate for structural support.
[0049]The first step to form a thick LED chip is to provide an assembly that includes a multilayer semiconductor structure on an optically transparent growth substrate. FIGS. 1A and 1B illustrate assembly 100 that includes a growth substrate 102 and a multilayer semiconductor structure 104. FIG. 1A is a...
