2018 eBeam Initiative Perceptions Survey Results


EUV confidence and multi-beam remains high in the 7th Annual Perceptions Survey – 2018 (July). EUV perceptions remain positive. 82% of respondents predict EUV in HVM by end of 2021. Only 1% predict EUV will never happen. Confidence is high again for EUV lithography in high-volume manufacturing and expectations continue to grow around actinic mask inspection for EUV. Perceptions on the nee... » read more

Planarization Challenges At 7nm And Beyond


Dan Sullivan, executive director of semiconductor technology at Brewer Science, digs into the challenges of planarizing a thin film on a wafer for etch and optical control. The problem becomes more difficult at advanced nodes because the films are thinner. https://youtu.be/iNA6EGpoYZU » read more

EUV Mask Blank Battle Brewing


Amid the ramp of extreme ultraviolet (EUV) lithography in the market, suppliers of EUV mask blanks are expanding their production. And a new player—Applied Materials—is looking to enter the market. AGC and Hoya, the two main suppliers of EUV mask blanks, are adding capacity for these critical components that are used for EUV photomasks. A mask blank serves as the substrate for a photomas... » read more

Multi-Beam Mask Writing Finally Comes Of Age


Elmar Platzgummer, chief executive of IMS Nanofabrication, sat down with Semiconductor Engineering to discuss photomask and mask writing trends. IMS, a subsidiary of Intel, is a supplier of multi-beam e-beam systems for photomask production. What follows are excerpts of that conversation. SE: For years, photomask makers have used single-beam e-beam tools to pattern or write the features on ... » read more

Using DSA With EUV


James Lamb, deputy CTO for advanced semiconductor manufacturing and corporate technical fellow at Brewer Science, looks at how directed self-assembly can be used to supplement EUV at advanced nodes. https://youtu.be/PItF4egHOxc     See other tech talk videos here » read more

The Impact of Moore’s Law Ending


Over the past couple of process nodes the chip industry has come to grips with the fact that Moore's Law is slowing down or ending for many market segments. What isn't clear is what comes next, because even if chipmakers stay at older nodes they will face a series of new challenges that will drive up costs and increase design complexity. Chip design has faced a number of hurdles just to get ... » read more

Wanted: Mask Equipment for Mature Nodes


Rising demand for chips at mature nodes is impacting the photomask supply chain, causing huge demand for trailing-edge masks and a shortfall of older mask equipment. The big issue is the equipment shortfall, which could impact customers on several fronts. Tool shortages could lead to longer mask turnaround times and delivery schedules for chips being developed at 90nm and above, which are bu... » read more

EUV Pellicle, Uptime And Resist Issues Continue


Extreme ultraviolet (EUV) lithography is moving closer to realization, but several problems involving scanner uptime, photoresists and pellicles need to be resolved before this long-overdue technology is put into full production. Intel, Samsung and TSMC are hoping to insert EUV into production at 7nm and/or 5nm. While the remaining issues don’t necessarily pre-empt using EUV, they do affec... » read more

Variation’s Long, Twisty Tail Worsens At 7/5nm


Variation is becoming a bigger challenge at each new node, but not just for obvious reasons and not always from the usual sources. Nevertheless, dealing with these issues takes additional time and resources, and it can affect the performance and reliability of those chips throughout their lifetimes. At a high level, variation historically was viewed as a mismatch between what design teams in... » read more

Survey: EUV Optimism Grows


The confidence level remains high for extreme ultraviolet (EUV) lithography, although the timing of the insertion remains a moving target, according to a new survey released by the eBeam Initiative. At the same time, the outlook for the overall photomask industry is bullish, according to the survey. On the downside, however, there appears to be no progress in terms of improving mask turnaro... » read more
