	During processing it is sometimes mandatory, necessary or just recommended to clean the wafers or the photo lithographic masks. This can be done by different cleaning procedures depending on what the wafers have been exposed to and where they are going to be further processed. In the comparison table below is listed different cleaning procedures available at nanolab.
