Re: tell me about chips

Integrated circuits (IC's), otherwise known as chips, is a large 
subject!!  
I recommend that you check in your university library under integrated 
circuits.  There are some books at the high school or lower levels that 
give a good explanation of the basic concepts.  You could also check the 
Institute of Electrical and Electronics Engineers (IEEE) web site.  Here 
are a few of the many books on this subject (these are all college level):

1) Carver Mead & Lynn Conway, Introduction to VLSI Systems, Addison-
Wesley, 1980, some fabrication and device physics, mostly device and 
system design.

2) S.M. Sze, Physics of Semiconductor Devices, second edition, John Wiley 
& Sons, 1981.

3) David J. Elliott, Integrated Circuit Fabrication Technology, McGraw-
Hill, 1892, how chips are manufactured.

4)Jacob Millman, Christos Halkias, Integrated Electronics: Analog and 
Digital Circuits & Systems, McGraw-Hill, 1972.

5) Arthur Glaser, Gerald Subak-Sharpe, Integrated Circuit Engineering-
Design, Fabrication and Applications, Addison-Wesley, 1977.

6) Paul Horowitz, Winfield Hill,  The Art of Electronics, second edition, 
Cambridge University Press, 1989.
