You could try reflow in a vacuum oven assuming the resist is amenable. Pull vacuum with the temp well above Tg. -Michael >>> Kevin Paul Nichols10/28/2008 1:38 PM >>> Do you have a desiccator present (bell-jar connected to a roughing vacuum pump)? If not, a "dirty" vacuum processing tool that nobody will mind having wet resist placed in? You might be able to get filling that way after doing your solvent/resist puddle. As a disclaimer, I haven't tried this myself, but I wouldn't think it would affect the resist much more than a poorly optimized soft bake would. - Kevin
