Forums - General Discussion - New IBM chip with 7nm wide transistors

http://www.npr.org/sections/thetwo-way/2015/07/09/421477061/ibm-announces-breakthrough-in-chip-technology

IBM says it has overcome a technological hurdle by producing a prototype chip with transistors that are just 7 nanometers wide, or about 1/10,000th the width of a human hair. The smallest transistors currently in use are twice as big.

The breakthrough occurred at SUNY Polytechnic Institute's Colleges of Nanoscale Science and Engineering. It could result in the ability to place 20 billion transistors on a chip the size of a fingernail.

According to The Wall Street Journal: "IBM's chip prototypes, which rely on a long-awaited breed of new production tools, don't prove its new technology will be practical in high-volume production, analysts said. But the developments could help IBM and its manufacturing partners pressure competitors like Intel Corp., while signaling that the industry can continue to overcome obstacles in boosting the speed, data storage capacity and power consumption of future chips."

Although IBM now subcontracts its chip production to Globalfoundries Inc., last year the computer giant announced a $3 billion investment over five years, partly to push the envelope on chip size. Thursday's announcement appears to be the fruit of that effort.

Ars Technica reports: "While it should be stressed that commercial 7nm chips remain at least two years away, this test chip from IBM and its partners is extremely significant for three reasons: it's a working sub-10nm chip (this is pretty significant in itself); it's the first commercially viable sub-10nm FinFET logic chip that uses silicon-germanium as the channel material; and it appears to be the first commercially viable design produced with extreme ultraviolet (EUV) lithography."

So, while we may be several years off a major hurdle has been cleared and could be feeling its impact across technology in coming decade.

Here's a pic of the chip:

It's a groundbreaking feat, the result of the IBM, GloFo and Samsung joint venture.

IBM is a company which mostly sells licences and allow the use of their patents these days. No wonder they spend so much on R&D with all the money they reap back from those. Either way, this is nothing new. IBM demonstrated 32 nm in 2004 and 22 nm in 2008. Their own chips didn't release on 45 nm before 2009-2010, so talk about a gap between IBM's laboratories and press releases, and their actual schedules.

Even if you take the release schedule from Intel, which always is the first to come with die shrinks due to their tick-tock process (now tick-tick-tock with Kaby Lake), and that's 4 to 6 years before the first commercial releases of products on these die manufacturing processes. The question remains whether a 7nm process will see their release date most closely mirroring the former or the later. On one side, chip costs are higher than ever, but on the other, there's a strong push for more efficient hardware on mobile platforms from Samsung and Apple.
