The articled failed to mention the most important aspects of the LED manufacturing: wafering and the MOCVD that deposits the light emitting materials
It didn't "fail to mention" that, it started with the pre-cut dies. This place turns cut dies into finished LEDs, and they documented what they saw. This was in China, and the dies are apparently made in Taiwan (so maybe they are crap), and they weren't anywhere near there.
And yes, fabs are serious alchemy. Like the time when Fairchild was a new company, and they found out that their transistor yields were being affected by workers not washing their hands after taking a leak. The chemicals in urine were fucking up the process.
