Flying lens lithography
WebOct 26, 2024 · Dr. Burn Lin, now an R&D executive at TSMC, had been scheduled to do a speech there. As originally planned, the speech was to discuss immersion lithography techniques and fluids to extend 157 nanometer lithography’s useful life. Several researchers had tested immersion techniques to extend 157 a few more years.
