How Extensively Will Curvilinear ILT Be Used For EUV Photomasks?


Curvilinear shapes on photomasks lead to improved process windows, as the first installment of this blog series discussed. Our blog series continues with a video panel discussion of the benefits that curvilinear shapes have for EUV photomasks (masks) and whether curvilinear shapes will be used beyond today’s usage for hotspots. Our panellists approached the question of curvilinear ILT for ... » read more

How Do Multi-Beam Mask Writers Enable Curvilinear Shapes On Photomasks?


Multi-beam mask writing was identified as one of the ways to eliminate hurdles to manufacturing curvilinear mask shapes in the last installment of this blog. Our blog series continues with an educational video explanation of why and how multi-beam writers reduce write time for curvilinear mask shapes that took place during an eBeam Initiative panel discussion with industry experts during the 20... » read more

What’s Next In AI, Chips And Masks


Aki Fujimura, chief executive of D2S, sat down with Semiconductor Engineering to talk about AI and Moore’s Law, lithography, and photomask technologies. What follows are excerpts of that conversation. SE: In the eBeam Initiative’s recent Luminary Survey, the participants had some interesting observations about the outlook for the photomask market. What were those observations? Fujimur... » read more

Curvilinear Full-Chip ILT


Leo Pang, chief product officer and executive vice president at D2S, talks about the speed improvements with full-chip inverse lithography technology, why it is so critical in stitching together large chips, and how this approach differs from traditional litho approaches. » read more
