Hi, Does anyone have suggestion on how to apply uniform resist on rectangular shape glass slides (1 x 3 inch)? I tried to spin them with full coverage of resist on slides, but the result is not good. Resist sometimes cannot reach corners, and it shows certain interference pattern under light, indicating the unevenness of resist thickness. Thank you.
