Why New Photoresist Technology Is Critical
By Rich Wise - 18 Mar, 2021 - Comments: 0

As chipmakers move to advanced technology nodes, they are challenged to resolve ever finer features. One of the major roadblocks involves the material used to transfer chip design to the wafer. That material is rapidly reaching its limit to accurately transfer designs. To keep next-generation device scaling on track, a breakthrough technology has been introduced: dry resist. To better understan... » read more

Long Lead Times Seen For Equipment
By Mark LaPedus - 18 Mar, 2021 - Comments: 1

There are a number of big stories in the semiconductor market thus far in 2021. Automotive chip shortages and tight foundry capacity are among the bigger ones. That’s just for starters. What hasn’t received much attention is the ongoing shortages and long lead times for semiconductor equipment. In some cases, lead times have stretched out to 12 months or more for some equipment. Some t... » read more

Two-beam EUV lithography At the recent SPIE Advanced Lithography conference, Nikon gave a presentation on a two-beam extreme ultraviolet (EUV) lithography technology. Still in the conceptual phase, Nikon’s so-called EUV Projection Optical Wafer Exposure Ruling Machine, or EUV Power Machine, is designed for the 1nm node or so. The proposed system has a minimum resolution of 10nm for lines ... » read more

Next-gen AFM At the recent SPIE Advanced Lithography conference, Imec, Infinitesima and others described a new metrology tool technology called a Rapid Probe Microscope (RPM). Infinitesima has shipped its first RPM 3D system, enabling three-dimensional (3D) metrology applications for leading-edge chips. The system was jointly developed with Imec. In the IEDM paper, Imec and Infinitesima... » read more

Breaking The 2nm Barrier
By Mark LaPedus - 18 Feb, 2021 - Comments: 4

Chipmakers continue to make advancements with transistor technologies at the latest process nodes, but the interconnects within these structures are struggling to keep pace. The chip industry is working on several technologies to solve the interconnect bottleneck, but many of those solutions are still in R&D and may not appear for some time — possibly not until 2nm, which is expected t... » read more

Imec’s Plan For Continued Scaling
By Paul McLellan - 14 Jan, 2021 - Comments: 0

At IEDM in December, the opening keynote (technically "Plenary 1") was by Sri Samevadam of Imec. His presentation was titled "Towards Atomic Channels and Deconstructed Chips." He presented Imec's view of the future of semiconductors going forward, both Moore's Law (scaling) and More than Moore (advanced packaging and multiple die). It is always interesting to hear Imec's view of the world sinc... » read more

AI And High-NA EUV At 3/2/1nm
By Mark LaPedus - 16 Dec, 2020 - Comments: 1

Semiconductor Engineering sat down to discuss lithography and photomask issues with Bryan Kasprowicz, director of technology and strategy and a distinguished member of the technical staff at Photronics; Harry Levinson, principal at HJL Lithography; Noriaki Nakayamada, senior technologist at NuFlare; and Aki Fujimura, chief executive of D2S. What follows are excerpts of that conversation. To vie... » read more

EUV Challenges And Unknowns At 3nm and Below
By Mark LaPedus - 19 Nov, 2020 - Comments: 1

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

What’s Next In AI, Chips And Masks
