28nm and further down

Definitely it is not true that 28nm is really complex and doesn't provide much yield The companies will not ivest without a strong information and their own experiments on the technology. But further down the line we need technologies like 3D and TSV to improve the power efficiency and smaller size.

The move to 28nm is happening now.  Processor and mobile device makers are leading the charge as they did at 45nm and as they will again at 20nm.  The Fabs and EDA vendors will scramble to improve the yields and improve the tools to allow the design community to develop their end products (smart phones, tablets, PC's).  At this point in the 28nm life cycle, one of the gating factors is the development of IP (standard cell libraries, memories, cores) for the designers to use.  They will all converge as they have for every other node and the process will begin again (it already has).

    Joanne, you are right. Power Leakage is a major concern and about 50% of the energy is going to be waste in 45nm process node. But in 28nm this power waste is very less and hence, the power efficiency can increase or power requirement can be decrease.  That would be one of the reason for increased  popularity of 28nm nodes.

High- K materials might fixed the leakage issue but it hasnt been proven practically. Being proposed by some research institutions - polymer ceramic nanocomposite material systems may be used in processing  to generate High - K such that value of K range between 80 and 200 @1MHz to 10GHz.

new amazing technologies will occur

When we moved down from 65nm integration to 45nm we have seen a lot of new technology occurred such as new computer with powerful processors,smart phones, tablets, etc. If the electronic industry break the 45nm obstacle and manufacture Asic with 28nm integration, then new amazing technologies will occur.

I hope we will see this to come soon, and we should not have to wait two years...

Dear anandvy,

You are correct, High-K, Metal Gate (HKMG) is one of the technology advances that is helping to improve the power leakage issue at 32nm/28nm.  At 22nm Intel is the first to introduce a new transistor structure.  3D Tri-Gate transistors take us to a whole new level.    Technology marches on!

"Leakage power is now 50 percent of total power consumption, he said."

Joanne,

 Can this leakage power be reduced using high-K dielectric materials or is this the optimal leakage power that we can achieve ?

These Transitions Aren't Cheap!

I agree that there were similar challenges and skepticism when there was the transition from 65nm to 45/40nm.

However, I'm not sure if I agree that 28nm will be short-lived... 28nm to 22nm doesn't seem to be as dramatic of an improvement as the 65nm to 45nm move for instance. Would making the transition AGAIN in such a relatively short period of time for some really be worth the additional power savings? Isn't it probably wiser to skip over 22nm in favor of 16/14nm?

Unfortunately, I'm not enough of an expert in this space to answer that question... so I'm really interested to see what other people's thoughts are.

Thanks for the article, Joanne, this is a subject I'm very interested in, but obviously have a lot to learn about!
