"One of those chemicals, known as photoresist, is critical for top-of-the-line products produced by Samsung Electronics, the giant South Korean maker of chips and gadgets, among others. Japan controls around 90 percent of the world's supply."

You gotta wonder how Japan got such a corner on that stuff. A lot like China has a lock on the rare-earths, I guess.
Was that Japan or another country that had some special epoxie (whatever) that was the covering for IC memory chips way back in the 1 K per chip days ?
China doesn't have a lock on rare earths. The ores are available in many countries, including Australia. What China does more than anyone else does is *process* the ore, because the processes are incredibly polluting and they don't care about pissing in their own pool. If they ever tried to really restrict trade in rare earths you'd find plenty of countries ramping up their processing programs.

"HF can burn the skin"
ROTFLMFAO! :-D
Yeah, I love how some stuff is understated. Like when all those lithium batteries in laptops were catching on fire. I read a report where the burning batteries were described as "venting with flame".
The batteries, or the Usenet trolls? :)
