Semiconductor Technologies Guide
An anonymous reader writes "X-bit labs have posted an interesting article on manufacturing technologies used in the semiconductor industry. Good reading if you want to get a really indepth idea of technologies used for semiconductor manufacturing by IBM, Intel, AMD, and others."
My guess is that no other industry in the world has the pace of tangible progress as microprocessors (except perhaps magnetic storage). Look back 30 years. Microprocessors were still in their infancy. The product of microprocessors have gotten 10's of thousands of times more powerful. Automobile manufacturing was, however, much as it still is today. The vast majority of textiles manufacturing is similarly unchanged in the last 30 years. History has demonstrated, though, that any fundamentally new technology goes through a very rapid period of development in a relatively short period of time. Eventually, all technologies level off in their pace of development.
I'm not sure I can answer your question, but I want to clarify something. I found this on google: diagram of a mosfet transistor.
Here's a simplified explanation. Think of a switch with source at one terminal and drain on the other. When sitting without a voltage on the gate, the source and drain are not connected. When the switch is turned on (ie. gate high), electrons are allowed through the pathway created.
Anyways, the yellow in the diagram is an insulator. The switching is all done without touching the doped silicon connecting the source and the drain. My point is that the silicon needs to be there. It's integral to how the switching works. I don't know anything about nano-tubes but it cannot replace the silicon unless it can act like a semiconductor (both as a conductor and insulator depending on temp, etc). Perhaps it could replace the SiO2 currently used as the insulating layer but no matter what, the smaller the channels get, the more the electrons are going to want to jump..
Anyone that knows more about SOI want to comment?
