Dear James, The 2% PMMA bottle is almost empty. Could you refill the bottle as soon as possible? I need to spin coat the 2% PMMA tomorrow for the session on Tuesday. Thank you for the help! -Byoungil -- Byoungil Lee Ph.D Candidate in Electrical Engineering Center for Integrated Systems Stanford University Phone: +1-650-796-9791 Email: bilee at stanford.edu
