Intel’s 22nm node will use bulk silicon, with a fully depleted tri-gate transistor structure. Instead of having the channel sandwiched between the. Separately, it announced a 22nm low-power FinFET node to compete for foundry business with fully depleted silicon-on-insulator (FD-SOI) from Confirms Move to Intel’s 22nm Process Featuring 3-D Tri-Gate Transistors. Contact: email @ Abstract. A 22nm generation logic technology is described incorporating fully-depleted tri-gate transistors for the first time.

Because of this, Intel has been able to innovate and integrate, adding more features and computing cores to each chip, increasing performance, and decreasing manufacturing cost per transistor.

The low-voltage and low-power benefits far exceed what we hri see from one process generation to the next. The capabilities give chip designers the flexibility to choose transistors targeted for low power or high performance, depending on the application.

I have to say I agree, some companies are keeping their gxte cards very close to their corporate chests these days! The three-dimensional Tri-Gate transistors represent a fundamental departure from the two-dimensional planar transistor structure that has powered not only all computers, mobile phones and consumer electronics to-date, but also the electronic controls within cars, spacecraft, household appliances, medical devices and virtually thousands of other everyday devices for decades.

The top of the fin is rounded, likely to avoid reliability problems from electric field concentration at corners. The Intel folks I talked to said that there was reluctance to publish, since the deplered leading-edge semiconductor companies were not presenting — conferences were no longer the exchange of information that they have been in the past.


Comments won’t automatically be posted to your social media accounts unless you select to share. Ivy Bridge is slated for high-volume production readiness by the end of this year. Also, no product was in the public domain at that point, though Intel claimed to be in production.

More than 6 million 22nm Tri-Gate transistors could fit in the period at the end of this sentence. Intel Ivy Bridge will use similar architecture to the existing Sandy Bridgethe basis of the current Core processor range. Anticipating this, Intel research scientists in invented what they called depletrd Tri-Gate transistor, named for the three sides of the gate.

In the gate metal, there seems to be a layer inetl titanium nitride TiN above the thin dark line that is the high-k, so we can surmise that the PMOS work-function metal is TiN, as in previous generations. There is no scale bar, so fin width is an unknown; and the taper on the fin is a bit of a surprise.

It has become the basic business model for the semiconductor industry for more than 40 years. That was the second-generation of so-called High k Metal gate transistors, which originally debuted in with 45nm processes and surplanted the Strained Silicon technology that had been in use since Intel Ivy Bridge official: For future generations, designers also have the ability to continue growing the height of the fins to get even more performance and energy-efficiency gains.


The 3-D Tri-Gate transistors are a reinvention of the transistor. Here we are looking at sections parallel to the gate, across the fin. Extension Media websites place cookies on your device to give you the best user experience.

An unprecedented combination of performance improvement and power reduction to enable new innovations across a range of future 22nm-based devices from the smallest handhelds to powerful cloud-based servers. Control of current is accomplished by implementing a gate on each of the three sides of the fin — two on each side and one across the top — rather than just one on top, as is the case with the 2-D planar transistor.

Alternatively, the new transistors consume less than half the power when at the same performance as 2-D planar transistors on 32nm chips. For the first time since the invention of silicon transistors over 50 years ago, transistors using a three-dimensional structure will be put into high-volume manufacturing. The SRAM operated at 4.
