IBM to enlist high-k metal gate technology with its 45nm chips

Alongside Intel’s news of 45nm process technology, IBM today announced its own 45nm technological advancements that apply to products manufactured in its East Fishkill, NY plant starting in 2008.

Working with AMD and its other development partners including Sony and Toshiba, IBM has found a way to construct a critical part of the transistor with high-k metal gates, that substitutes a new material into a critical portion of the transistor that controls its primary on/off switching function. The material provides superior electrical properties compared to its predecessor, silicon dioxide, enhancing the transistor's function while also reducing leakage.

As important as the new material is the method for introducing it into current manufacturing techniques. The creation of this transistor component with the new material was accomplished by the IBM team without requiring major tooling or process changes in manufacturing - an essential element if the technology is to be economically viable.

“Until now, the chip industry was facing a major roadblock in terms of how far we could push current technology,” said Dr. T.C. Chen, vice president of Science and Technology, IBM Research. “After more than ten years of effort, we now have a way forward. With chip technology so pervasive in our everyday lives, this work will benefit people in many ways.”

Will AMD use high-K?

After reading the IBM release, not sure what to think. High-k wasn't mentioned at IEDM, but they claim to have a solution. I am sure IBM can have a process ready for 45 nm, but AMD would need to plan this for their 45 nm fab if they still want to do it.

Well to be fair, Intel didn't mention it at IEDM either...

Minor detail is that INTEL did NOT annouce their 45nm at IEDM while AMD/IBM did.

By design or not INTEL choose not to say much at IEDM. I can only suspect the delay was by design. I can ask why wouldn't IBM annouce HighK if it was indeed planned on their 45nm x86 line. I'm sure INTEL wanted to annouce functional Penrym which is what they have now. I can only concluded that perhaps they didn't have functional CPUs in hand at the conference deadline.

I'm not clear, but is sure looks like IBM has little to annouce but a reactionary annoucment timed to coincide with INTEL's with little/NO details, but a me too. If you look at INTEL's annoucement it seems much more prepared, pictures of wafers, fancy diagrams, and lastly a fully functional x86 64 bit CPU too.

I only refer to this interesting quote from an IBM executive. Does this sound like someone ahead or someone really caught with his pants down and reacting?

"It’s the difference between can openers and Ferraris"
...I.B.M. had simply chosen to deploy its new process in chips that are part of high-performance systems aimed at the high end of the computer industry. Its good to know that IBM executives see x86 CPUs as canopeners. I sure AMD is glad to know that is what the IBM guys think of them and their Dresden fab. Just a canopener. IBM is doing much more important things then bothering with HighK for x86.

I'm sorry what is more important then deploying the latest silicon technology on the most visible product, x86 CPUs.

Oh.. I know IBM was saving it for power, maybe that is the secret sauce that is going to get POWER to 5 GHz. Or maybe they are saving it to get higher yields on Cell. What a crock response.

IBM's and AMD's production processes have been closely linked for some time now, so assuming that Intel and IBM see some tangible gains from using this technology, AMD will assuredly use it.
