– SPIE EUV & Photomask conference well attended with great talks
– Chip industry focused on next gen High NA EUV & what it impacts
– Do big chips=big masks? Another Actinic tool?
– AI & chip tools, a game changer- China pre-empting more sanctions
High-NA EUV lithography is the anticipated new lithography technology to be introduced for the 2nm node. Essentially, it replaces the 0.33 numerical aperture of current EUV systems with a higher 0.55 numerical aperture (NA). This allows the projection of smaller spot sizes and smaller pitches, roughly 60% smaller compared … Read More
Current 1a-DRAM and 5/4nm foundry nodes have minimum pitches in the 28 nm pitch range. The actual 28 nm pitch patterns are one-dimensional active area fins (for both DRAM and foundry) as well as one-dimensional lower metal lines (in the case of foundry). One can imagine that, for a two-dimensional routing pattern, both horizontal… Read More
The “1.xnm” node on most roadmaps to indicate a 16-18 nm metal line pitch [1]. The center-to-center spacing may be expected to be as low as 22-26 nm (sqrt(2) times line pitch). The EXE series of EUV (13.5 nm wavelength) lithography systems from ASML feature a 0.55 “High” NA (numerical aperture), targeted… Read More
The next generation of EUV lithography systems are based on a numerical aperture (NA) of 0.55, a 67% increase from the current value of 0.33. It targets being able to print 16 nm pitch [1]. The High-NA systems are already expected to face complications from four issues: (1) reduced depth-of-focus requires thinner resists, which… Read More
-KLA has another great QTR in face of overwhelming demand
-Supply chain issues obliterated by backlog
-Longer term technology leadership concerns are increasing
-We see limited upside near term & remain cyclically cautious
KLA’s performance remains great as does… Read More

High-NA EUV has received a lot of attention ever since Intel put the spotlight on its receiving the first 0.55 NA EUV tool from ASML [1], expected in 2025. EUV itself has numerous issues which have been enumerated by myself and others, most notoriously the stochastic defects issue. There are also a host of issues related to the propagation… Read More
-Intel’s access to high-NA EUV tools may be their elixir of life
-TSMC’s EUV adoption helped it vault faltering Intel & Samsung
-Maybe ASML should invest in Intel like Intel invested in ASML
-Shoe is on the other foot- But cooperation helps chip industry
Intel is dependent upon ASML for its entire future
If Intel… Read More
The successful transition to a new fabrication process from development to high volume manufacturing requires a collective, collaborative effort among process engineers, equipment manufacturers, and especially, chemical suppliers. Of particular importance is the chemistry of the photoresist materials and their interaction… Read More
