@NickParkerPrint @FutureJurvetson @dch_nl @farzyness The bottom right image on the first tweet suggests mask, but with gas field ionisation you get a highly collimated beam. So a mask doesn't make sense.

@atAlanBell @FutureJurvetson @dch_nl @farzyness Interesting but not what I’m asking. I’m asking once you have this beam, how are you adding/removing layers from actual dies, what’s the mask and exposure setup like

Introducing Ⓛ 𝗟𝗔𝗖𝗘 𝗟𝗜𝗧𝗛𝗢𝗚𝗥𝗔𝗣𝗛𝗬 A novel approach to chip-making that can extend Moore's Law 10x beyond what is possible with light — to atomic resolution. News today: "Manufacturers use light-based lithography systems made by the Dutch company ASML, which dominates ​the market. Lace has developed a new approach. Instead of ​light, Lace's engineers have made a form of lithography that uses a helium atom beam. With that, the Norwegian company will be able to create chip designs that are 10 times as small as what is currently possible" "The main advantage of the helium atom beam is the industry could create features such as transistors, ‌the ⁠building blocks of modern chips, an order of magnitude smaller to an "almost unimaginable" degree, according to John Petersen, Scientific Director of Lithography at Imec, a research and innovation hub for the chip industry. The beam Lace will use to make chips is about the width of a single hydrogen atom, or 0.1 nanometer. ASML's lithography tools use ​a beam of light that ​is about 13.5 nanometers; ⁠a human hair is about 100,000 nanometers wide. Smaller transistors and other features would give chipmakers the ability to ramp up the performance of advanced AI processors well beyond ​the current capabilities. Lace's technology would enable chip manufacturers to print wafers at ​what is "ultimately atomic ⁠resolution" — reuters.com/world/asia-pac… Now hiring in Bergen and Barcelona: LaceLithography.com

@NickParkerPrint @FutureJurvetson @dch_nl @farzyness And the beam current will be very low ~pA. I would be interested to know what is being patterned is it resist and then pattern transferred into the active material

@NickParkerPrint @FutureJurvetson @dch_nl @farzyness From the schematic and the asterisk above the He it is a gas field ion source. This will give high resolution because you need very high fields to ionize helium. However, ionisation will only take place at the single atom (likely of a 3 atom or trimer configuration).

@FutureJurvetson What is the beam current?

@arxiv Unrelated but do we know the first paper? And where is it now in terms of citations etc

Here’s the only player in PGA Tour history to Happy Gilmore it off the first, can’t remember his name but what a legend. Happy release day @shootermcgavin @AdamSandler

@IanCutress Ian what is the reason for 10nm vanishing 4 years ago? Is tsmc 10nm similar to intel? Expensive node that does yield?

The raw per-node numbers show that 5nm is almost pulling in $10b a quarter all by itself.v

@aandr314 @quantumbeans Is it not Horizontal Field Width? But yeah those match!

@atAlanBell @quantumbeans at least Half-Full Widths (HFWs) are the same!

thermal field emitter (top) vs cold field emitter (bottom) both images are the same scale

@aandr314 @quantumbeans But the mags are different!

@YonCalahorra @beamshift Any milling going on? Interesting that it seems to be in a TFS PFIB. And we're at 52. Nice image

@PhysicsSteve I always find h index quite interesting. Like, lowest h index of Nobel Prize winner. Lowest h index age rated (h index matching ones age). Worst citations per h index. There's a lot!

It may not be much compared to most who've been in the game as long as I have, but I'm quietly pleased to have just hit a meaningless citation milestone. 🙃 About half of it was in the last 18 months, so I guess I'm doing something right these days. 🤔

@ClippersSD @JayPosnerSD Let's not forget chasing Marty out. Could be a while before a 14 win coach is fired

@JayPosnerSD Guy was kind of an arrogant jerk. Started out making all the right moves. Got full of himself and then ran the team to the ground chasing away good players (i.e Vincent Jackson) & replacing them with awful draft choices (Buster Davis) and non-impact free agents (Robert Meachem).

More sad news for the local sports scene.

@BillyThomson80 @ED_TABS_90 @mark_j1979 @wallface @CapersColly What is the charge?

To the family who left the restaurant this evening without paying their £329 bill shame on you!!

@JustinRayGolf @Daniel_Rapaport @ForePlayPod Can we get a legacy one and include Monty?

@Daniel_Rapaport @ForePlayPod Fowler and Schauffele have tons of high major finishes, giving them boosts over Hovland, Cantlay, etc. Obviously it's not perfect, but was always a fun exercise back in the day.

Along with Viktor, are these the two current best/most accomplished players without a major championship?

@kclairerogers She's incorrect it was actually 3 years ago that the car saved him

A gal in the crowd is telling her friends that this tournament is called the Genesis and is hosted by Tiger because that’s the car that saved his life four years ago
