Hi Paul,

This is to let you know that your chemicals have been approved.

The resist should only be spun up at Headway  please use your own 
plastic cassette to store before bake,  or the LOL2000 cassette,  this 
resist will satin.
Please cover the hotplate with foil and make sure to remove them when done.

The lift off should be done at wbsolvent in the white light area and NOT 
at litho solvent.
Please come by to log in your chemicals and  get the labels from me.  Ed 
and Mary can help with this as well, I will be on vacation next week.
The storage group is L

Your chemical will go in to yellow cabinet all the way in the back of 
furnaces, not sure ask a staff.
