To make 45nm process manufacturing easier: just add water

Intel has said on multiple occasions that its 45nm process is on track for production 2007. In fact, Intel began sampling its Penryn 45nm chips just several weeks ago. At the IEDM, IBM and AMD described three technologies that hope to compete with Intel’s 45nm development: the use of immersion lithography, which AMD says will “deliver enhanced microprocessor design definition and manufacturing consistency,” ultra-low-K interconnect dielectrics to enhance performance-per-watt ratio and multiple enhanced transistor strain techniques.

Current process technologies use conventional lithography, which has significant limitations in defining microprocessor designs beyond the 65nm process technology generation. Immersion lithography uses a projection lens filled with purified water as part of the step-and-repeat lithography -- think of the same principles applied to immersion microscopy.

Immersion lithography provides increased flow of light, depth of focus and improved image fidelity that can improve chip-level performance and manufacturing efficiency. For example, the performance of an SRAM cell shows improvements of approximately 15 percent due to this enhanced process capability, without resorting to more costly double-exposure techniques.

In addition, AMD and IBM say that the use of porous, ultra-low-K dielectrics reduces interconnect capacitance, wiring delay, as well as lowering power dissipation. This advance is enabled through the development of an ultra-low-K process integration that reduces the dielectric constant of the interconnect dielectric while maintaining the mechanical strength. The addition of ultra-low-K interconnect provides a 15 percent reduction in wiring-related delay as compared to conventional low-K dielectrics.

In spite of the increased packing density of the 45nm generation transistors, IBM and AMD demonstrated multiple enhanced transistor strain techniques that give an 80 per cent increase in p-channel transistor drive current and a 24 per cent increase in n-channel transistor drive current compared to unstrained transistors. The companies claim that their achievement results in the highest CMOS performance reported to date in a 45nm process technology.

In November 2005, AMD and IBM announced an extension of their joint development efforts until 2011 covering 32nm and 22nm process technology generations. AMD and IBM expect the first 45nm products using immersion lithography and ultra-low-K interconnect dielectrics to be available in mid-2008.

LOL, seriously, dream on fanboi. AMD wanted 65nm in 2005 aswell. AMD can maybe ship 45nm in 2009. Maybe! Only reason AMD can say 56nm for 2006 is due to a paperlaunch, else it would be 2007.

Its not like their process shifts have been going good for them. 65nm is delayed and low speedbins, tho you said in July they would increase ;)

Also found a funny quote:
""By then Conroe will run circles around it and at HALF the power consumption. Dunno about this

Mate, you must have received glasses during Valentines Day as they appear to be rose coloured..."

1. You are making up the "$1200"
2. Where on Earth did you get "HALF the power consumption" from?"

C2Q vs 4x4? Anyway Viditor, you been more wrong than right. And your AMD bias always catches up with you in history. Good luck hoping for 45nm AMD chips before 2009, and good luck hoping K8L will even beat C2D/C2Q. And say welcome to budget/volume market.

Ahhh...it's Shintai, King of the Intel oscillating airflow devices! :)

As I'm sure that Intel wanted 22nm in 1986...what's your point?
BTW, AMD's first working 65nm chips came out at the launch of Fab 36 in October of 2005...

I assume you mean 65nm...(USE the preview) :)
AMD 65nm has been shipping for awhile already...it says clearly in AMD's FAQ that they are OEM-only parts.

This should be obvious as the only real difference between the 90nm and 65nm part (functionally) is that the 65nm uses much less power. For desktop, this is only really important for OEM designs, so they really aren't targeted for the channel at all.

Oh, and I forgot to add. Intel ships 45nm CPUs in Q3 2007

Hmmm...not according to Intel.
http://techreport.com/etc/2006q4/fall-idf/index.x?...
From the Fall IDF in October...look at the slide and note that Penryn isn't due to ARRIVE until after 2007.

Shipping in H2 2007 can mean Dec 31 2007, and it takes a month after initial shipping for availability.

Regardless, the news here in Aloha is that the fab is producing 45nm as we type.
