Calvin, I used Wetbench Metal yesterday before you and the chemical were all new. And PRS1000 is supposed to be changed only once in a month. Why did you still drain it? If you really need to process some wafers, you can use a clean bicker to contain enough PRS1000 and clean your wafers it after heating it up to 40oC. The dump rinse and spin dry procedures would be the same.

Hi Sir:


I wonder if there is anyone who happened to be here this Sunday and have the authorization to get more PRS-1000 to the chemical store area.


Thanks a lot

To users of wbmetal,wbgen2, wbgeneral and wbgaas:

Our chemical distributor informs us that our regular allotment of 
PRS1000 will be delayed by a few weeks.  We are trying to find stock 
elsewhere, but it seems to be a problem with manufacturer so little luck 
so far.  Please, please conserve your use of PRS1000 as our supplies are 
very low.

- Do not drain/change the shared PRS1000 baths unless OK'ed by staff.
- At general wet benches, use PRX-127 if your process allows.

Thanks for your cooperation and patience --

Your SNF Staff
