The dependence of substrate material and electrode position were studied by radiation analysis of Ar discharge, and electron beam radiation was applied to confirm the crosslinked structure of the film. Comparing the conductor substrate with the insulator substrate, the former had lager peak density of radiation spectrum than latter. From the result of peak density of metastable state and ion, it was confirmed that the peak density of ion was falling to the down limit with increasing the distance of electrode by analyzing the radiation spectrum of polymerized films. When the polymerized styrene films was exposed to electron beam, it was possible to form a pattern with the insulator substrate.
