Standard E-beam resists and process guidelines
DTU Nanolab offers a limited number of standard EBL resist for our users. Our standard resist and process guidelines are summarized below. CSAR (AR-P 6200.09) is installed on Spin coater Gamma E-beam & UV for spin coating of 2", 4" and 6" substrates. Other substrate sizes or resist have to be used in the Labspin 2/3 coating systems. The standard resist bottles are stored in the chemical cupboard in E-4.

Non-Standard E-beam resists
It is possible to obtain permission to user other resists at DTU Nanolab, users must however provide these resists and possibly developers themselves. A non-exhaustive list of user supplied EBL resist used at DTU Nanolab and some process guidelines can be found in the table below.
