High-NA EUV May Be Closer Than It Appears


High-NA EUV is on track to enable scaling down to the Angstrom level, setting the stage for chips with even higher transistor counts and a whole new wave of tools, materials, and system architectures. At the recent SPIE Advanced Lithography conference, Mark Phillips, director of lithography hardware and solutions at Intel, reiterated the company’s intention to deploy the technology in high... » read more

Why Mask Blanks Are Critical


Geoff Akiki, president of Hoya LSI at the Hoya Group, sat down with Semiconductor Engineering to talk about optical and extreme ultraviolet (EUV) lithography as well as mask blanks. What follows are excerpts of that discussion. SE: Mask blanks are components that serve as the base or the substrate for a photomask. Why are they critical? Akiki: If you look at Hoya, we've been positioned as... » read more

Vector Runahead


Abstract: "The memory wall places a significant limit on performance for many modern workloads. These applications feature complex chains of dependent, indirect memory accesses, which cannot be picked up by even the most advanced microarchitectural prefetchers. The result is that current out-of-order superscalar processors spend the majority of their time stalled. While it is possible to bui... » read more

EUV Pellicles Finally Ready


After a period of delays, EUV pellicles are emerging and becoming a requirement in high-volume production of critical chips. At the same time, the pellicle landscape for extreme ultraviolet (EUV) lithography is changing. ASML, the sole supplier of EUV pellicles, is transferring the assembly and distribution of these products to Mitsui. Others are also developing pellicles for EUV, a next-gen... » read more

EUV Challenges And Unknowns At 3nm and Below


The chip industry is preparing for the next phase of extreme ultraviolet (EUV) lithography at 3nm and beyond, but the challenges and unknowns continue to pile up. In R&D, vendors are working on an assortment of new EUV technologies, such as scanners, resists, and masks. These will be necessary to reach future process nodes, but they are more complex and expensive than the current EUV pro... » read more

Manufacturing Bits: May 26


7-level nanosheets The 2020 Symposia on VLSI Technology & Circuits for the first time will be held as a virtual conference. The event, to be held from June 15-18, is organized around the theme “The Next 40 Years of VLSI for Ubiquitous Intelligence.” Among the papers at the event include advanced nanosheet transistors, 3D stacked memory devices and even an artificial iris. At the ... » read more

Manufacturing Bits: May 19


Virus simulations Using an advanced building simulator and testbed, Lawrence Berkeley National Laboratory (Berkeley Lab) is launching a study of the risk of airborne transmission of viruses in buildings. Researchers will also explore the ways to mitigate those risks. The experiments will take place in Berkeley Lab’s FLEXLAB, which is an advanced building simulator. Used by builders, archi... » 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
