Nik Dee, How are you using chlorobenzene? When I've used it, it has been after exposure but before development. There is no exposed silicon at this part of the photolitography (well, the edge and the backside are exposed, but there's no pattern there). So, my point is that perhaps more details will make it clearer what your difficulty is.

It looks like there is some rection between the Chlorobenzene and the silicon and the features of the S1813 are destroyed. Does anyone know how to get around this?
