Sadly, yet another shiny penny, another in the 30+ year search for an alternative to optical. Not sure whether this is due to ADD on the part of lithographers, or simply the "nice from far but from nice" syndrome of those without perspective. We have poured billions into X-ray (a.k.a. EUV) without commercial success. What makes anyone think you can start with yet another shiny penny at the 10nm node? Its bizarre. The only technologies that can succeed are those built on the optical lithography infrastructure. There is only one.
We are fast approaching the lower limit, since the crystalline lattice of silicon, for instance, has a spacing of about 0.5 nm. But scientists who work with these tiny dimensions call .5nm, 5 angstroms, and the atoms themselves are much much smaller--measured in hundreds of picometers (1pm = 1/100th of an angstrom).
SRC claims this is the first production ready use of directed self assembly--that previous demonstrations were just test structures, but that Stanford's technique is ready for 22-nm today, can be extended as-is to 14-nm, and is being developed for single-digit geometries by formulating new co-polymers.
"Directed self-assembly (DSA)—a technology based on a concept that was virtually unknown outside of research labs a few years ago..."
A Book For All Reasons Bernard Cole1 Comment Robert Oshana's recent book "Software Engineering for Embedded Systems (Newnes/Elsevier)," written and edited with Mark Kraeling, is a 'book for all reasons.' At almost 1,200 pages, it ...
