I am looking for pyrex wafer which has the thickness of less than 250um. Originally, I want 170 um thick pyrex wafer. As far as I have found, I can get 250um thick pyrex wafer. If someone know which vendor sells that thin pyrex wafer, please let me know. Thank you. ===== Chang-Hwan Choi Brown University Division of Engineering, Box D Providence, RI 02912, U.S.A.
