What Happened To DSA?

By Mark LaPedus - 19 May, 2016 - Comments: 2

Directed self-assembly (DSA) was until recently a rising star in the next-generation lithography (NGL) landscape, but the technology has recently lost some of its luster, if not its momentum. So what happened? Nearly five years ago, an obscure patterning technology called [gettech id="31046" t_name="DSA"] burst onto the scene and began to generate momentum in the industry. At about that t... » read more

The Next Resists

By Katherine Derbyshire - 22 Oct, 2015 - Comments: 5

As EUV exposure tools, sources, and photomasks have become more capable, the lithography sector’s attention has turned to EUV photoresist. After all, once the exposure system can produce a high quality image at the wafer, the resist still has to capture it for pattern transfer. Unfortunately, the increasing emphasis on photoresist has made the limitations of current formulations even more obv... » read more

5 Reasons EUV Will Or Won’t Be Used

By Michael Watts - 19 Mar, 2015 - Comments: 1

Digging into this subject, there are five metrics that count in a lithography tool: resolution, throughput, defects, overlay, and reliability. So what does the best data tell us about the current state and realistic prognosis for [gettech id="31045" comment="EUV"]. Semiconductor Engineering posed this question to Matt Colburn, senior manager for patterning research at [getentity id="22306" comm... » read more

Swimming In Data

By Ed Sperling - 21 Mar, 2013 - Comments: 0

By Ed Sperling So many warnings about data overload have been issued over the past decade that people generally have stopped paying attention to them. The numbers are so astronomical that increases tend to lose meaning. Nowhere is this more evident than in the semiconductor metrology world, where files are measured in gigabytes. And at each new process node, as the number of transistors a... » read more
