Novel Assist Layers To Enhance EUV Lithography Performance Of Photoresists On Different Substrates


In EUV lithography, good resist patterning requires an assist layer beneath it to provide adhesion to prevent pattern collapse of small features and allow for higher aspect ratios. In addition, future EUV high numerical aperture (NA) is expected to require a decrease in thickness from the overall patterning stack. In this study, we are exploring a fundamentally new approach to developing an alt... » read more

High-NA EUVL: the next major step in lithography


"In the course of 2025, we expect to see the introduction of the first high-NA extreme ultraviolet (EUV) lithography equipment in high-volume manufacturing environments. These next-generation lithography systems will be key to advance Moore’s Law towards the logic 2nm technology generation and beyond. In this article, imec scientists and engineers involved in preparing this major engine... » read more

Improving EUV Process Efficiency


The semiconductor industry is rethinking the manufacturing flow for extreme ultraviolet (EUV) lithography in an effort to improve the overall process and reduce waste in the fab. Vendors currently are developing new and potentially breakthrough fab materials and equipment. Those technologies are still in R&D and have yet to be proven. But if they work as planned, they could boost the flo... » read more

Will AI Drive Scaling Forward?


The almost ubiquitous rollout of AI and its offshoots—machine learning, deep learning, neural nets of all types—will require significantly more processing power as the amount of data that needs to be processed continues to grow by orders of magnitude. What isn't clear yet is how that will affect semiconductor manufacturing or how quickly that might happen. AI is more than the latest buz... » read more

EUV’s Uncertain Future


The ground appears to be solidifying under EUV. Intel announced this week it is reducing its stake in ASML to less than 3%, the second such move in a year. Apparently ASML no longer needs outside help. According to the company's earnings report, ASML turned in net sales of €2.776 billion, a slight increase over the €2.447 billion (GAAP) the company reported in Q3 and way up over the €... » read more

Next EUV Issue: Mask 3D Effects


As extreme ultraviolet (EUV) lithography moves closer to production, the industry is paying more attention to a problematic phenomenon called mask 3D effects. Mask 3D effects involve the photomask for EUV. In simple terms, a chipmaker designs an IC, which is translated from a file format into a photomask. The mask is a master template for a given IC design. It is placed in a lithography scan... » read more
