I think they will have problem with positive charging of the surface.

To speed up the e-beam and make it more shaper reaching 9nm is excellent research and the scanning method instead of integral method made this win for the researchers.

The abstract read that all structures with 15 nm hp and above were fully resolved, but smaller ones had some resist residues. 15 nm hp is also about the limit current demonstrated by spacer etching.

Is resolution of 9nm possible from other other technologies like Photomask ? If answer is no then inspite of throughput issues e-beam resolution will become attractive.

I love the idea of "Extreme Ultraviolent UV" :)

The only thing I was impressed by was they could use few keV electrons, but the lithographic result is still too familiar, very rough lines and non-uniform dots in very thin resist. It is not a fault of the technique but a natural consequence of electrons being free to move after being released or injected in a film.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
