Post how do they make circuits very small

Can someone give me a web page that explains the process of how millions of transistors can be packed in a small space?

What you want to look for is "silicon planar processing" - the manufacturing process that creates and connects the millions of transistors on a silicon die. The fact that there are millions, and today billions, of transistors is a by product of the improvements in manufacturing capabilities and tolerances; namely the etching process.

If you can get access to a copy of Microelectronic Circuits by Sedra and Smith (I suggest you look in your library) one of the appendix gives a very detailed overview of the process.

The process involves photolithography and chemical etching as well. The process is to complex and I don't know the details, but googling based on these two terms can be a start. You should go for the book that Dave suggested if you can access it in a public library.

Further to the Sedra and Smith book, can I suggest you try and have a look at CMOS VLSI design by Weste and Harris. They have an accompanying website: http://www.cmosvlsi.com/

http://en.wikipedia.org/wiki/Semicon...ce_fabrication

This should give you a decent overview.
