摘要:
A light-emitting diode (LED) includes a plurality of reflective layers stacked over each other and each comprising a distributed Bragg reflector, a substrate, an N type semiconductor formed on the substrate, a light emitting layer formed on the N type semiconductor layer and a P type semiconductor formed on the light emitting layer. The stack of the reflective layers is formed under the substrate or the stack is formed between the substrate and the N type semiconductor layer. The reflective layers receive and reflect light incident at different angles thereby alleviating escape of light from the light emitting diode and enhancing overall brightness of the light emitting diode.
摘要:
A manufacturing method and a structure of a light-emitting diode (LED) chip are disclosed. The method includes the steps of: providing a conductive block; providing an epitaxial block; bonding; removing an epitaxial substrate; making independent LEDs; forming a dielectric layer; and making electrical connection. A first LED, a second LED, and a third LED are formed on the conductive block, wherein the first and second LEDs are electrically connected in series, and the second and third LEDs are electrically connected in parallel. Thus, a basic unit with a flexible design of series- and parallel-connected LEDs can be formed to increase the variety and application of LED chip-based designs.
