Can you please tell me which are the different problems that VLSI design technology is facing and what are the proposed remedies for these problems?
Can you suggest a few links or e books also if possible.
VLSI technology is currently researching on the light barrier problem which restricts us in having circuits having size of 3.2nm(approx) which is roughly 2 Si atoms thick and right now it is believed that devices smaller than that cannot be made....
also lots of research is going on in the fabrication of inductor in an IC....
I think Silicon can no more be used for IC designing ....... It has its own barrier for speed...
The mobility of electron in Si is less so the speed of operation is less, so we need to go in for devices with higher mobility viz.. GaAs and carbon nano tubes,organic transistors,single electron transistors....
Thanks to all you for giving such good replies. But I want to have a detailed picture of such problems. So can you please suggest a few links from where I could read more about such problems facing VLSI design technology?
To answer your question ,
there is a good link which discusses the ASIC chip implementation challenges(rather the issues) and how to address up-front in the design cycle to resolve this issue...
