The patterning of organic layer materials is often hindered by the effects of the conditions used to “develop” the resist material, for example high temperatures for strong bases, which attack the substrate. The process described here allows the patterning even of delicate layers of oriented nonlinear optical polymers. The figure shown a patterned polyimide film 115 μm thick.
