Recent articles have focused much effort on studying the stochastic behavior of secondary electron exposure of EUV resists [1-4]. Here, we consider the implications of extending similar treatments to DUV lithography.
Basic Model Setup
As before, the model uses pixel-by-pixel calculations of absorbed photon dose, followed… Read More
Extreme ultraviolet (EUV) lithography is often represented as benefiting from the 13.5 nm wavelength (actually it is a range of wavelengths, mostly ~13.2-13.8 nm), when actually it works through the action of secondary electrons, electrons released by photoelectrons which are themselves released from ionization by absorbed… Read More
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
At SEMICON West I had a chance to catch up with Mike Lercel of ASML. In this article I am going to combine ASML presentation material from the SPIE Advanced Lithography Conference, Mike’s SEMICON presentation, my discussions with Mike at SEMICON and a few items from ASML’s recent earnings call.
DUV
ASML continues to improve DUV systems.… Read More
At the 2023 SPIE Advanced Lithography and Patterning conference, ASML presented an update on its EUV lithography systems in the field [1]. The EUV wafer exposure output was presented and is shown below in table form:
From this information, we can attempt to extract and assess the EUV wafer output per quarter. First, since there … Read More
Intel held a webinar today to discuss their IDM2.0 internal foundry model. On the call were Dave Zinsner Executive Vice President and Chief Financial Officer and Jason Grebe Corporate Vice President and General Manager of the Corporate Planning Group.
On a humorous note, the person moderating the attendee questions sounded … Read More
