very good reading.
in one person's words, "deep enough to be insightful, but short enough that your eyes won't start bleeding."
An Introduction to Semiconductor Physics, Technology, and Industry.
(there are seven pages, and the comments section is not too bad either)
fwiw, this 90-min video is also pretty darn good re: semiconductor manfacturing.
GLAL,

PS:
for any adventurious, ambitious soul looking for something to do, this would be great PDF'd and put into the link library. :-)
