I understand a micron is one millionth of a metre.  When people say,
"The Pentium uses a 0.35 micron process", etc, what does that mean?
What is 0.35 micron?  Is it the minimum width of circuit tracks?  Is it
the area covered by a transistor?

How many micron do our PIC's use?  How many micron were the first
commercial chips?

And some other mysteries while I am here :
Who decided that the 74LS00 would be a quad 2-input nand gate, and for
the rest of the series?
Why does using a smaller micron process make a chip faster and draw less
power?



Thanks,
David.
