Optics & Photonics News - A Roadmap for Optical Lithography

The periodic enhancement in the resolution achieved through photolithography has been a driving force behind Moore's Law. Resolution improvements enable printing of smaller geometries on an integrated circuit. The minimum feature size that a projection system typically used in photolithography can print is given approximately by: where WebK1 factor decrease – K1 factor was 0.6-0.7 in production environment – Today most aggressive k1 in production is 0.3 –Physical limit for single exposure is 0.25 – Using DE/DP k1 could be pushed down to 0.22 ÎThis will allow to print features less than ¼ of the exposure wavelength ipt to stp
