Optical Lithography, Take Two

By Mark LaPedus It’s the worst-kept secret in the industry. Extreme ultraviolet (EUV) lithography has missed the initial stages of the 10nm logic and 1xnm NAND flash nodes. Chipmakers hope to insert EUV by the latter stages of 10nm or by 7nm, but vendors are not counting on EUV in the near term and are preparing their back-up plans. Barring a breakthrough with EUV or other technology, IC ... » read more

Challenges Grow For EUV

By Mark LaPedus In the late 1990s, a group led by Intel launched a consortium to propel extreme ultraviolet (EUV) lithography into the mainstream. Originally, the consortium, dubbed the EUV LLC, envisioned the advent of EUV scanners that would move into production at the 65nm node. Clearly, the now-defunct consortium underestimated the difficulties and challenges associated with EUV. ASM... » read more
