The Uncertain Phase Shifts of EUV Masks

EUV (Extreme UltraViolet) lithography has received attention within the semiconductor industry since its development inception in 1997 with the formation of the EUV LLC [1], and more recently, since the 7nm node began, with limited use by Samsung and TSMC being touted as key advantages [2, 3]. As with any key critical technology,

0.33 NA EUV systems for HVM Ron Schuurhuis Page 02

I couldn’t attend the SPIE Advanced Lithography Conference this year for personal reasons, but last week Mike Lercel of ASML was nice enough to walk me through the major ASML presentations from the conference.

Introduction
In late 2018, Samsung and TSMC introduced 7nm foundry logic processes with 5 to 7 EUV layers, throughout … Read More

The Need for Low Pupil Fill in EUV Lithography 1

Extreme ultraviolet (EUV) lithography targets sub-20 nm resolution using a wavelength range of ~13.3-13.7 nm (with some light including DUV outside this band as well) and a reflective ring-field optics system. ASML has been refining the EUV tool platform, starting with the NXE:3300B, the very first platform with a numerical

SPIE EUV 2020 Coronavirus

Corona Curtails already quiet SPIE Litho conference
Our best guess is that attendance was off by 30% from last years SPIE conference due to a lack of travelers from many Asian areas obviously out of Corona fear. Even Intel, which is a few miles away was a virtual no-show with a mass cancellation.

More importantly, virtually all after… Read More
