Qualcomm and other Samsung clients could get a boost from novel power-saving gate design

At the Intel Develop Forum, the world's largest maker of traditional PC central processing units and server chips, Intel Corp. (INTC) is fond of expressing how it's crushing its rivals in process technology.  But by the looks of it the rest of the pack may not be as far behind as Intel would like to have you believe.

On Friday, Samsung Electronics Comp., Ltd. (KSC:005930announced that it had successfully taped out a 14 nm FinFET transistor chip.  For those who don't avidly follow the CPU design industry, most traditional transistors are flat multi-layer designs (think a sandwich).  By contrast the FinFET uses a tall wall-like gate, which towers over the nanoscopic surface like a fin.  The novel 3D design allows leakage to be significantly reduced -- a key source of loss in reliability and power at sub 40-nm designs.

Intel was the first player to get FinFETs, with its 22 nm Ivy Bridgelaunched earlier this year.  It plans to roll over the technology into its mobile offerings next year.  But by the sound of it Samsung won't be far behind.

Samsung worked with a chip-optimizing firm called Synopsys to perfect the difficult process of producing the delicate FinFETs at such a small node.

Samsung LSI vice president Dr. Kyu-Myung Choi cheers, "FinFET transistors can deliver lower power consumption and higher device performance, but they also bring tough challenge.  We chose Synopsys as our FinFET collaboration partner to solve these challenges, because of our successful history together at 20 nanometer and other nodes. We continue to pool our expertise to deliver innovative FinFET solutions."

Synopsys's expertise helped Samsung characterize the prototype chips and to remove so-called "parasitic" impurities.

The chipmaking duo did not announce a time frame for commercial rollout.  But when Samsung does achieve commercial mass-production of 14 nm FinFETs, one interested party will surely be Qualcomm, Inc. (QCOM) whose SnapDragon 4 system-on-a-chip (SoC) design Samsung recently began producing at its monolithic Texas chipmaking facilities.

RE: Intel taped-out 14nm six months ago...

Yes, there is a huge difference in taping out a chip and mass producing it. In one case it is a first cut at the completed design (tape out) and the other is actually mass producing devices in quantities of millions. This article seems to make it feel like going from one stage to the other is trivial. It is not. (The perfect example is the Motorola G5 chip. It taped out then took many, many months to get from test batches to pre production. When the pre production chips were tested in the field errors were found that would have caused a vast chip redesign -- some of which were process based -- so Motorola killed it. For the past decade or more for CPUs/GPUs process and architecture are closely integrated -- hence Intel's tic-toc approach to try to deal with this by decoupling it as much as possible.)

Additionally, the article does not say the number of gates or transistors in the design. Was this design just for a 1,000 transistor proof of concept? If so, then don't expect to see 14 nm FinFET CPUs from Samsung for a few more years!

I believe I saw other tech news sites state that Samsung has used Cortex-A7 as its test vehicle and has produced a functional chip. It's nowhere near as complex as current top of the line x86 CPUs but it's no 1000 transistor chip either.

Yeah, time between tapout and qual is going to be 1-2 years. Tapout, eng samples, etc, etc and finally qual before any of this gets sold to Tier1 customers.
