Yes, anything at all to do with semiconductors is expensive, because 
you need ultra clean rooms, fine geometries, and dangerous chemicals. 
(And I mean _real_ semiconductors, not cats whiskers :-)
But ... there`s a way. 

MOSIS (1-213-822-1511) is the best bet for the small experimenter. $500 gets
you 4 packaged parts in cmos 2 micron technology,
132 pin pga max. They have a modem number; you give them yoiur design data
base in electronic form, and at their next scheduled run (they have
runs every 1-2 weeks. ), they run your design through with many others,
and mail you the parts. Good for prototyping an idea
