Samsung: full speed in advance for 10nm, EUV deploys on the 7nm node

The photograph above suggests why businesses retain to claw for EUV lithography, no matter its troubles, strength expenses, and vastly extended cooling necessities. modern-day generation is based totally on 193nm wavelengths of ArF excimer lasers, however this approach can not scale to the tiny function sizes utilized in cutting-edge lithography. One approach to this hassle is to apply multipatterning, in which the equal wafer runs thru extra publicity steps to create the final etch. The hassle with multi-patterning is that it’s each difficult and expensive — and it slows the overall wafer throughput of the fab. If etching a wafer used to require 60 mask and multi-patterning increases that to ninety masks, there’s a full-size throughput hit and a extra danger that defects could be delivered sooner or later in the manufacturing process.

intense ultraviolet lithography uses 13.5nm wavelengths of ultraviolet mild to image a good deal finer functions and keep away from the bulky and high-priced multi-patterning system. The motive EUV has taken goodbye to come back to marketplace is that operating with wavelengths of mild this small is fairly difficult — there were myriad issues associated with disorder density, the want to work in close to-vacuum situations, problems with the lasers themselves, and the shortage of a suitable pellicle, or thin movie membrane that protects the photomask from particle infection. All of these troubles are why Intel and TSMC have each implied they gained’t introduce EUV till they hit the 5nm node.

Samsung, in evaluation, is forecasting EUV adoption at 7nm. If the business enterprise hits that focus on, it might give it a large potential price advantage over its foundry opponents — however most effective if the EUV hardware is ready to come back on-line. betting and missing on EUV as a 7nm solution may want to cripple Samsung’s foundry technology if TSMC and Intel wager on conventional scaling strategies and spot higher consequences.

What’s rolling out in 2016?

Samsung is pronouncing some of near-time period enhancements and modifications to its 2016 product roadmaps, which include:

•New 28nm options for RF and eNVM (embedded non-risky reminiscence);

•14nm LPC: a 3rd-era value-optimized 14nm procedure node. 14nm may even get an RF choice as an add-on this 12 months;

•10nm: Samsung will debut a 10nm LPP (Low power Plus) with 10% better performance than Low energy Early.

a few notes on these milestones: while a foundry says its ramping a product solution, that doesn’t imply that generation is truely prepared for shipping client designs but. There’s a tremendous lag time depending on product circle of relatives, foundry area, and customer validation — Apple offered early 14nm manufacturing from both TSMC and Samsung, even as other smartphones and portraits cards took 6-one year to transition to the new node. Samsung may well be ramping a second-generation 10nm node, however that doesn’t imply quit customers may be shopping for 10nm-magnificence device in six months.

Samsung is typically offering extra equipment, surroundings alternatives, and abilities like 2.5D interposers for HBM and reference design flows. these varieties of capabilities are essential to many one of a kind styles of customers and investments like this factor to Samsung taking the foundry market critically.

As usually, remember the fact that the term “node” is used somewhat differently through the one of a kind foundries. Intel’s 14nm and 10nm nodes are authentic feature shrinks across the board, even as both Samsung and TSMC used a hybrid technique for his or her sixteen/14nm merchandise. Samsung’s 10nm is notion to be a hybrid among the 10 and 14nm nodes, simply as 14nm is a hybridized 14nm / 20nm technique.

The question in recent times isn’t so much whether or not Intel is technically in advance in the foundry sport — it's far, and will probably stay, inspite of its new, not on time cadence. The query is whether or not those gains stay really worth the charges, and while the foundry node cut back economics fail altogether. An EUV rollout at 7nm or 5nm will push matters alongside a bit at the same time as longer, however what happens after this is nonetheless largely unknown.
