摘要:
Disclosed in the application are a synthetic silica glass having low fluence-dependent transmission, particularly at about 193 nm, and a process for making the same. The glass may desirably exhibit a low level of fluorescence at 290 and 390 nm when activated at about 248 nm. The glass may desirably exhibit low level of LIWFD, [SiH*] and/or [ODC].
摘要:
Disclosed are synthetic silica glass having a low polarization-induced birefringence, process for making the glass and lithography system comprising optical element made of the glass. The silica glass has a polarization-induced birefringence measured at 633 nm of less than about 0.1 nm/cm when subjected to excimer laser pulses at about 193 nm having a fluence of about 40 μJ·cm−2·pulse−1 and a pulse length of about 25 ns for 5×109 pulses.
