Browsing through my computer, I stumbled upon my early work summaries from when I first embarked on learning about LEDs. It brought back memories of my days fresh out of graduation, and I'd like to share this with those who are now graduating and stepping into the industry.

LED stands for Light Emitting Diode, a phenomenon of electroluminescence. Here's a simplified schematic diagram to illustrate:

Interpretation of the Blue Light Chip Process

Photolithography involves exposing and developing a photoresist to transfer the pattern from a photomask onto the thin film layer or silicon wafer beneath it. The process includes steps such as photoresist coating, baking, photomask alignment, exposure, and development.

ICP (Inductively Coupled Plasma) dry etching uses Ar gas as the plasma source and Cl2 as the reactant gas. By meticulously controlling the gas ratio and power conditions, superior etching results can be achieved.
