-The dicers feature versatile processing capabilities, compact designs, and high precision and reliability. Users perform workpiece loading, alignment, and unloading manually.
+DTU nanolab has 2 saw available for dicing substrates into separate chips. Both tools offer versatile processing capabilities, high precision and reliability.
-The dicers at DTU Nanolab is placed in room 157 on the first floor in bldg. 346. Please notice that this is not a cleanroom and that the dicing process is very dirty.

-In general it is ''not allowed'' to bring back your samples into the Cleanroom. You need approval from DTU Nanolab staff to do this, follow the instructions [[Specific Process Knowledge/Wafer cleaning/Bring samples into cleanroom|here]] to apply for approval. Your samples have to be thoroughly cleaned in the gowning area and get a Piranha cleaning. You will only be allowed to use a limited number of tools for the processing after dicing.
