For samples with 2D materials such as graphene, HBN, etc., it is '''mandatory''' to apply a 20 nm Al layer on top of the resist in order to expose the substrate in the JEOL 9500 system. The Raith eLine system does not have this requirement.

Another possibility is to use a spin-on conductive layer such as [https://www.allresist.com/wp-content/uploads/sites/2/2021/05/Allresist_Product-information-Protective-Coating-AR-PC-5090_5091-English-web.pdf AR-PC 5090]. It can be removed with water after exposure. At the moment we do not have much experience with this, contact the EBL team if you are interested in this option.
