Increased Photomask Density And Its Impact On EDA
By Ed Sperling - 13 Dec, 2022 - Comments: 0

The ability to print curvilinear shapes on photomasks can have big repercussions on semiconductor design. Aki Fujimura, CEO of D2S, explains why mask rule checking has been bound by complex design rules, and why curvilinear shapes are important for reducing margin and simplifying the chip design process. » read more

High-NA EUV Complicates EUV Photomask Future
By Jan Willis - 17 Nov, 2022 - Comments: 0

The eBeam Initiative’s 11th annual Luminaries survey in 2022 reported EUV fueling growth of the semiconductor photomask industry while a panel of experts cited a number of complications in moving to High-NA EUV during an event co-located with the SPIE Photomask Technology Conference in late September. Industry luminaries representing 44 companies from across the semiconductor ecosystem partic... » read more

Why Changes In Computing Are Driving Changes In Photomasks
By Ed Sperling - 18 Oct, 2022 - Comments: 0

Aki Fujimura, CEO of D2S, talks with Semiconductor Engineering about massive improvements in computation based upon increased density on chips, and why printing Manhattan shapes on a photomask are no longer sufficient to print high-performance devices with predictable reliability every time. He explains why a discontinuity in EDA physical design has opened the door for printing curvilinear shap... » read more

For The Love Of Theatre And Mask-Making
By Jan Willis - 05 Jul, 2022 - Comments: 0

Naoya Hayashi has been a friend and important contributor to the eBeam Initiative from our start over 13 years ago. We’re just one of the many interests he has embraced and championed over his 45 year career at DNP. Now it’s our turn to embrace him and thank him for the wonderful memories as he pursues his next chapter after retiring as the first research fellow from DNP this June. Aki Fuji... » read more

The Changing Mask Landscape
By Jan Willis - 19 May, 2022 - Comments: 0

Semiconductor photomasks have undergone some major technology changes in the past few years after relatively minor changes for many years. New technologies such as multi-beam mask writers and extreme ultraviolet (EUV) lithography are major breakthroughs as they ramp into high-volume manufacturing. A new trend related to these technologies is the use of curvilinear features on photomasks. Aki... » read more

Using GPUs In Semiconductor Manufacturing
By Ed Sperling - 25 Apr, 2022 - Comments: 0

Massive simulation and curvilinear shapes are forcing the photomask industry to rethink what types of chips work best. Aki Fujimura, CEO of D2S, talks about what happens when shapes printed on a mask are closer to what actually gets printed, how GPUs can be used to accelerate CPUs in single instruction/multiple data (SIMD) operations, and why pixel data is different from other data. » read more

Photomask Shortages Grow At Mature Nodes
By Mark LaPedus - 21 Apr, 2022 - Comments: 2

A surge in demand for chips at mature nodes, coupled with aging photomask-making equipment at those geometries, are causing significant concern across the supply chain. These issues began to surface only recently, but they are particularly worrisome for photomasks, which are critical for chip production. Manufacturing capacity is especially tight for photomasks at 28nm and above, driving up ... » read more

The Right Project Is Key For Photomask Adoption Of Deep Learning
By Jan Willis - 17 Feb, 2022 - Comments: 0

Deep learning (DL) has become an integral part of the success of many companies. There have been many papers and some reported successes in semiconductor manufacturing, yet only 22% of the luminaries participating in the 2021 eBeam Initiative Luminaries survey see DL as a competitive advantage for photomask making by next year, as shown in figure 1. Looking at that chart, the luminaries believe... » read more
