There are still three major technological lithography options for high volume manufacturing at the 32 nm half pitch node: 193 nm immersion lithography with high index materials, enabling NA > 1.6; 193 nm double patterning and EUV lithography. In this paper the pros and cons of these three options are discussed. The extendibility of these options beyond… (More)
In this paper, the experiences on full field EUVL lithography are reviewed. Besides the imaging performance of the EUV ADT at IMEC, also the progress in resists and reticles are discussed and compared to the production requirements for EUV lithography.
