In comparison, there are 40 lithography layers for at 22nm/20nm chips, 19 of which are critical layers. In total, there are 52 lithography exposures at 22nm/20nm, 31 of which are immersion exposures ...

Scanning-Beam Interference Lithography is being commercialized at the Plymouth Grating Laboratory (Mark Schattenburg’s company. Using our scanning beam interference lithography technique, optical ...

Palo Alto, Calif. -- August 16, 2004 -- Optical lithography may currently offer the advantage of high wafer throughputs, but to sustain in the long term and compete with the next generation ...

However, optical lithography has far from reached the end of the road, and will continue to be used for some years, adopting light sources of smaller wavelengths (such as ArF and F 2 excimer ...

In optical lithography, light shines through a mask–a type of stencil–onto a substrate, such as a silicon wafer, that’s coated with a light-sensitive chemical called a photoresist.

Extending optical lithography toward the 193-nm wavelength is expected to provide feature sizes of 65-nm and beyond for the high-volume production of advanced memory and semiconductor devices.
