Latest Patents
Li-Ming Shu holds a patent for a light-emitting diode fabrication method. This method includes several key steps: providing a substrate, forming a low-temperature AlGaN layer over the growth substrate, and adjusting growth conditions to transition from three-dimensional to two-dimensional growth of the GaN structure layer. The process also involves doping silicon near the multiple quantum-well layer to create undoped and N-type gradient GaN layers. Furthermore, it includes growing a multiple quantum-well layer, an AlGaN layer, and a P-type layer. During chip fabrication, the epitaxial wafer is divided into chip grains, which are then immersed in chemical solutions for wet etching. This innovative method culminates in the formation of an inverted pyramid structure with rough side walls over the multiple quantum-well layer, significantly improving light-emitting efficiency.
