Nanometer processor to picometer processor

post #1 of 12
8/16/10 at 5:04pm
Thread Starter 
So I started thinking the first nanometer processors were introduced about 6 years ago at a nice whopping 90nm if I can recall right and 6 years later we have gone all the way down to 32nm and rapidly approaching 22nm and smaller. So what happens when we get to 1nm size processors? Well we get to the picometer. Is making a proccesor with a lets say 90picometer or 90pm process technology even possible? If so how long do you think until we start seeing them? Less than 5 years? 5 years? 10 years?

Disclaimer: Sorry if I sound retarded these small scales I'm not familiar with.

I personally think we are reaching physical limits at like 22nm>X>5nm. This is a big question that only patience can answer.

22nm they will just call it

220 picometer

I'm not an engineer, but we've seen how fragile the 32nm processors are. 22nm will probably be made of glass and toothpicks, and anything under that is probably beyond the physical limit.

Personally, I think we'll see a completely new type of processor before we see a 90pm processor.


Oh, and, side note - Moore's "law" is such BS. It's not a law at all, just speculation.

Biggest problem is heat. You could make it smaller true, but it could become as hot as the exhaust from a rocket.

EDIT: I agree with AyeYo as well. A new design/type of processor will probably come out before it get smaller.

What I don't understand is why there's such reluctance towards making the die bigger. I understand the benefits of making the process smaller, but there has to be a limit somewhere, and it would seem easier/more cost effective to just make the die bigger. Who's idea was it to have this completely arbitrary general die size and attempt to always stuff more transistors onto it?

If you have a 5mm x 5mm die with 500 million 90nm transistors, you can either halve the process size to 45nm to get 1 billion transistors or you could just double the die size to 10mm x 10mm... Aside from heat and power consumption, why wouldn't that work?

We are reaching nm boundaries. 22/16/11nm will probably be the end.


To answer ayeyo's question, people always want smaller. Till we find out how small we can make chips, we wont really increase the size of them.
