Not at all.

How big are the features on a typical mask used in photolithography then?

the chip is produced by shrinking the mask optically onto the silicon
wafer...


Yes, which means that the detail is very fine - tolerances on the order of
wavelengths of light and even X-rays.

Indeed - but is the mask that fine or is the image focued through a much
bigger mask?

I dunno about you, but the 1.99ukp cheapies dont seem to last more
than a year, maybe three before the strap goes...

I go with *quality* product - Timex ;-)
