Photo of the pattern for contrast curveStiched image by OLS5000 (5X)HSQ: 3000 rpm, 220 nm, PreBake 150 deg x 2 min, Development: NWD-W, 4 minutes, at 23.0 degree 9 x 9 x (5X), took some 30 mins to scan, actual geometry is some 21 x 21 m/m Line and Space measures 64 / 64 (um) basic dose range set as 0.5 to 15.99 verically dose ratio 35/40/45/50 from left to the right resulting dose range: 17.5 to 560 (35, to the left)
The left most column is scanned by DekTak Each four pair is made up by two columns, one on the left: for DekTak recognition, the right: for true log scale (dose/distance) for OLS5000 scanning, but I could not get profile image from this yet |
