How To Extend Litho Scaling


IC mask [getkc id="80" comment="lithography"] today is sophisticated and complex. It's also a work in progress with a lot of unknowns as the industry struggles to increase productivity while reducing risk. The bulk of the work currently is focused on trying to figure out what would be a practical scheme for patterning lithography that could be used at 10nm and 7nm, said Gandharv Bhatara, Ca... » read more

What If EUV Fails?


It’s the worst kept secret in the industry, but extreme ultraviolet (EUV) lithography will likely miss the 10nm node. So, chipmakers will likely extend and use today’s 193nm immersion lithography down to 10nm. This, of course, will require a complex and expensive multiple patterning scheme. Now, chipmakers are formulating their lithography strategies for 7nm and beyond. As it stands now,... » read more
