Make The Impossible Possible: Use Variable-Shaped Beam Mask Writers And Curvilinear Full-Chip Inverse Lithography Technology For 193i Contacts/Vias With Mask-Wafer Co-Optimization


Abstract: "Full-chip curvilinear inverse lithography technology (ILT) requires mask writers to write full reticle curvilinear mask patterns in a reasonable write time. We jointly study and present the benefits of a full-chip, curvilinear, stitchless ILT with mask-wafer co-optimization (MWCO) for variable-shaped beam (VSB) mask writers and validate its benefits on mask and wafer at Micron Tec... » read more

Enabling Curvilinear Masks


This talk by Leo Pang, Chief Product Officer of D2S, takes a look at a unique GPU-accelerated approach to curvilinear inverse lithography technology (ILT) and introduces mask-wafer co-optimization (MWCO) that enables writing curvilinear ILT for 193i on VSB or multi-beam machines in 12 hours. » read more
