Abstract
Official abstract text for this publication.
A light emitting diode (LED) structure, a LED device and methods for forming the same are provided. The LED structure comprises a LED wafer; and a phosphor layer having a flat surface and formed above a light emitting surface of the LED wafer, in which the phosphor layer is formed by centrifugal spin coating.
First claim
Opening claim text (preview).
What is claimed is: 1. An LED structure, comprising: an LED wafer; a transparent accommodating layer directly formed on a light emitting surface of the LED wafer, wherein the transparent accommodating layer is conductive and has a recess; and a phosphor layer having a flat surface and formed in recess of the transparent accommodating layer, wherein the phosphor layer is formed by centrifugal spin coating. 2. The LED structure according to claim 1 , furth…
