Seeking to satisfy a potential gap in the market, GlobalFoundriesIntel and TSMC are racing to develop new processes targeted at 22nm. Time will tell whether 22nm will become a popular node like 28nm, or just a niche, but it does give foundry customers some new options. Meanwhile, in another possible option, TSMC recently announced a new 22nm bulk planar process. And then, Intel rolled out a new, low-power version of its 22nm finFET technology.

All told, there is no one process that fits all applications. Each foundry customer has a different set of requirements for a given IC design. The decision boils down to several metrics, such as power, performance, area scaling, schedule and cost PPASC.

Why 22nm? Not long ago, chip customers simply followed the node progressions and developed products around each technology. Companies developing chips at the most advanced nodes require the performance benefits of leading-edge processes.

And demand remains robust for 28nm and above. Generally, 28nm demand is expected to dip in the first quarter due to normal seasonal issues, but it will bounce back later this year, Yen said. UMC itself has not made any announcements regarding 22nm. The IC design costs and risks are too high. To get a sufficient return on investment, a chip must generate sales that are 10 times greater than the overall design cost, according to International Business Strategies IBSa market research firm.

For that reason and others, fewer customers can afford to move to advanced nodes. Of course, the leading-edge foundry customers, such as Apple and Qualcommgenerate enormous volumes for foundries. And you also have a cost premium. All told, the 28nm planar node has emerged as the sweet spot for many in the industry, as it combines the right balance of performance, power, area scaling and cost PPASC for applications.

In fact, despite being introduced several years ago, 28nm will remain viable for some time. Going forward, many customers will end up staying at 28nm and above. For those customers, there is another option—22nm. Based on the enhancements that you see in terms of performance and area, there is no significant wafer cost between 28nm and 22nm. For that reason, 22nm makes sense, although others have a different view.

Plus, 28nm is selling at very low wafer prices. Regardless, just in case the market takes off, customers must look at the 22nm options. For example, in bulk CMOS logic, a silicon wafer maker develops a raw wafer.Sinjin Dixon-Warren, Posted on December 11, by rwilliamson. Our analysis suggests that this will be a very profitable technology platform for TSMC and for their fabless design partners for many years to come.

In fact, Chairman Morris Chang expects that 28 nm will be the biggest node ever, exceeding the 65 nm node in production volumes, with more thanwafers per month at the peak. Historically, TSMC was used to a slower ramp with leading customers such as FPGA vendors Altera or Xilinx; with 28 nm the ramp included Qualcomm and other mobile-driven companies, and demand switched on much more quickly.

According to their web site their total manufacturing capacity in was TSMC claims that their 28 nm process technology entered production in ; however, production devices were not available for analysis until mid These companies make high value, relatively low volume devices, and thus can afford the relatively low yields seen in the early ramp of a new CMOS technology. It should be no surprise that often the first devices at a new technology node to hit our labs come from these vendors; and it has been thus since our analysis of the nm Altera Stratix in and the 90 nm Altera Stratix II in Back then, the Altera Stratix feature cobalt silicided poly transistors with a nm contacted gate pitch, while the transistors in the Stratix II had a nm contacted gate pitch.

We published our Structural Analysis Report in July of Hafnium oxide based dielectric was used for the HK layer, over a 2. The contacted gate pitch for the transistors in the XC7KT is nm. Our Process Review Report was published in October of The features a 0. TSMC claims that the 28 nm LP process is the low cost and fast time to market choice, ideal for low standby power applications such as cellular baseband.

The process apparently provides a 20 percent speed improvement over the 40 nm LP process at the same leakage per gate. The minimum contacted gate pitch was nm.

The 40 nm LP process featured a nm contacted gate pitch in the logic regions. This process is targeted at mobile applications and apparently will support both high performance transistors and low power transistors on the same die, thus enabling higher performance mobile devices, while continuing to improve power performance, which is critical in battery powered gadgets. The HPM process has not yet been seen in the market yet, but Chipworks expects to see an example of the technology soon in a mobile device from a leading manufacture sometime soon — possibly a future variant of the Apple A6.

Silicon germanium has a lower bandgap than elemental silicon, such that it is better for the absorption of infrared radiation. However, silicon germanium has poor compatibility with CMOS processes for the logic devices due to increased leakage current.

As such, manufacturing the logic devices on silicon germanium introduces difficulties and adds cost to the manufacture of the CMOS image sensors. The present application is directed to a CMOS image sensor with elemental silicon and silicon germanium for long-wavelength pixel sensors. In some embodiments, an elemental silicon layer abuts a silicon germanium layer. By arranging the photodetector in the silicon germanium layer, the photodetector advantageously has good sensitivity to and absorption of long-wavelength radiation, such as, for example, infrared radiation.

Further, by arranging the transistor on the elemental silicon layer, conventional CMOS processes may advantageously be used when forming the transistor. In other embodiments, the silicon germanium layer is partially or fully covered by the silicon layer Anonymous May 26, at PM. Anonymous May 29, at PM.

Other chipmakers, including GlobalFoundriesIntel and Samsungalso are looking at technologies for 5nm and beyond. Both 5nm and 3nm present a multitude of unknowns and challenges. For one thing, the specs of these technologies are murky, if not confusing. And not all of the technologies are alike. The roadmaps, of course, could change. But for now, Intel plans to ramp up 10nm in the second half ofwith 7nm slated for production in early to mid, according to industry sources. For now, Intel plans to extend the finFET to 7nm, sources added.

Beyondhowever, the roadmap is uncertain. The leading transistor contenders for a full-scaled 5nm technology right now include finFETs with new materials, gate-all-around FETsand a related technology called nanosheet FETs. Another viable option is to go vertical and adopt a 2. By then, IC scaling might be too expensive or could grind to a halt. Design costs will continue to skyrocket.

Uncertainty Grows For 5nm, 3nm

This will put fully integrated 5nm chips out of reach for a large number of consumer applications, and limit them to only the market segments demanding the highest levels of performance and those willing to pay for it. For this, researchers are exploring several technologies.

Nonetheless, given the enormous costs for these technologies, the question is clear: Why bother developing 5nm technology and beyond? The industry, according to some, will require these advanced processes for use in future servers and mobile systems as a means to deal with a major onslaught of data hitting the market. So how does the industry continue to scale?

Semiconductor Engineering has taken a look at the technology options at these nodes, such as finFETs, nanowires and 2. Confusing nodes Not everyone will move to advanced nodes, of course.It is commonly used as a semiconductor material in integrated circuits ICs for heterojunction bipolar transistors or as a strain -inducing layer for CMOS transistors.

IBM introduced the technology into mainstream manufacturing in The use of silicon-germanium as a semiconductor was championed by Bernie Meyerson. SiGe processes achieve costs similar to those of silicon CMOS manufacturing and are lower than those of other heterojunction technologies such as gallium arsenide. Recently, organogermanium precursors e. SiGe foundry services are offered by several semiconductor technology companies. SiGe allows CMOS logic to be integrated with heterojunction bipolar transistorsmaking it suitable for mixed-signal circuits.

This translates into better low current and high frequency performance. Being a heterojunction technology with an adjustable band gapthe SiGe offers the opportunity for more flexible band gap tuning than silicon-only technology. SGOI increases the speed of the transistors inside microchips by straining the crystal lattice under the MOS transistor gate, resulting in improved electron mobility and higher drive currents.
