Latest Patents

Chiou's latest patents include a novel light emitting diode and a method for fabricating high efficiency light-emitting diodes. The first patent describes a light emitting diode that incorporates a Bragg reflector layer with high reflectivity. This design prevents emitted light from being absorbed by the substrate, resulting in a brighter LED. The Bragg reflector layer consists of high aluminum-containing AlGaAs/AlGaInP layers, which enhance reflectivity and create high reflection zones. This structure allows for better current limitation within the oxidized regions, leading to increased brightness compared to conventional LEDs.

The second patent outlines a method for fabricating high efficiency LEDs adhered to a transparent substrate. This process begins with the formation of a semiconductor substrate, followed by the creation of various layers, including an etching stopper and a double heterostructure. A transparent substrate, such as glass, is then adhered to the LED structure, allowing for improved luminous intensity. The method significantly reduces the use of GaAs material, enhancing the absorption of visible light and overall efficiency.
