Intel Shrinks Transistor Size By 30% 258
pinkUZI writes "Intel will announce that it has crammed 500 million transistors on to a single memory chip, shrinking them in size by 30%. " The tech details are sadly lacking in the article - but I'm sure those will follow. Indeed, the Yahoo piece gives the details that "...has created a fully functional 70 megabit memory chip with transistor switches measuring just 35 nanometers."

But as a rule of thumb, the closer you bunch up the transistors, the higher the electrical leakage. This is why the current chips are consuming more power than ever. At 65 nanometers, we'll be 30 percent smaller but also leak 30 percent more. This leakage causes heat.
Intel's paperwork shows that they believe that practical transistors will stop shrinking at approximately 320 watts/cm^2 which is nearing the heat density of a nuclear reactor (500w/cm^2). This will take place at the 45nm level in 2007.

It's not the bunching up (density) of the transistors that increases leakage current (static power consumption,) it's the gate size. Narrower gates are less good at being the perfect insulators they should be. The thinner dielectric allows more leakage current, and can even break completely if the voltage is too high, which is why smaller-geometry processes often allow (or require) lower operating voltages, which helps reduce synamic (switching) power.
Of course, it's the shrinking of the gates (and the rest of the transistors) that allows them to be bumched up more (placed in higher density,) so maybe you meant it that way . . .

I think your describing the wrong mechanism - deep submicron device leakage is dominated by drain-source subthreshold currents (hot-electron effects and whatnot), not by gate-source currents.

And while neither of us pointed out all three, the fact remains that it's not the "bunching up" of the transistors that increases leakage, it's the gate and transistor sizes (which tend to scale together.) Which was the point I was trying to make.
If you think gate leakage is negligible compared to sub-threshold leakage, you'd better tell the IEEE [66.102.7.104] and all those people working on high-K gate dielectrics [google.com].

Re:Heat (Score:5, Informative)
Smaller transistors generally require less power to operate because they can (actually, must) be operated at a lower voltage. Dynamic (swtiching) power varies with the square of the voltage, so dropping the voltage a little makes the power go down a lot.
But that's just switching power.
As gate sizes shrink, previously negligible leakage (static) power increases. A lot. Now it's no longer negligible at the 90nm and 65nm process steps. In fact, it's getting very close to the same order of magnitude as switching power.
That's a problem because you can limit dynamic power by switching more slowly, or not switching certain transistors at all (think mobile CPU speed throttling.) But leakage power is consumed even if the CPU clock isn't ticking. If voltage is applied to the chip, power leaks.

"The Santa Clara, Calif.-based company said Monday it has created a fully functional 70 megabit memory chip with transistor switches measuring just 35 nanometers -- about 30 percent smaller than those found on today's state-of-the-art chips."
Now according to Google, there's 10,000,000 nanometers to a cm. Our chip is 35 nm in size. 10,000,000 divided by 35 is 285,714. So we now know that we can put 285,714, 35nm chips in a 1cm strip.
OK, here are your errors:
Original post: No, it is not 10 MB per square 35 nm, the transistors have 35 nm gate lengths, simply meaning the lenth of poly cut to form the gate is 35 nm, probably at least 3x as wide (can't really say without detailed knowledge of their layout). The overall transistor foot print is going to be MUCH bigger than a 35 nm square, as you haven't even included the source and drain, let alone contacts!
Now on to your second post. You say "Our chip is 35 nm in size." It is obvious you do not work for Intel if you are saying your chip is 35 nm in size. The chip is going to be MASSIVE compared to 35 nm (see above point) once you put 500,000,000 of them on the chip.
