Many Options For EUV Photoresists, No Clear Winner


In EUV lithography, and especially high-numerical-aperture EUV, balancing tradeoffs between resolution, sensitivity and line-width roughness is becoming increasingly difficult. Lithography patterning using extreme UV exposure depends on a resist mask that can simultaneously meet targets of small feature resolution, high sensitivity to EUV wavelength, and acceptable linewidth roughness. Unfor... » read more

EUV’s Future Looks Even Brighter


The rapidly increasing demand for advanced-node chips to support everything-AI is putting pressure on the industry's ability to meet demand. The need for cutting-edge semiconductors is accelerating in applications ranging from hyperscale data centers powering large language models to edge AI in smartphones, IoT devices, and autonomous systems. But manufacturing those chips relies heavily on ... » read more

EUV’s New Problem Areas


Extreme ultraviolet (EUV) lithography is moving closer to production, but problematic variations—also known as stochastic effects—are resurfacing and creating more challenges for the long-overdue technology. GlobalFoundries, Intel, Samsung and TSMC hope to insert [gettech id="31045" comment="EUV"] lithography into production at 7nm and/or 5nm. But as before, EUV consists of several compo... » read more
