There is increased contamination in the photolith hoods. Surveillance cameras are on the way. There was also interest expressed in re-instituting the user clean up duty. Sign up sheets for hood use was discouraged. There is a legal issue on the installation of high pressure lines.
Spin dryers are a preferred solution, but there is a severe space problem.
Eventually 2 spin dryers will be installed in the photolith area. The present hood nitrogen guns will be modified to give higher pressure and flow and still comply with safety issues. The CMP is down. Dan W. is addressing. There is problem with response from the vendor.
