High Resolution Positive E-Beam Resist With Dry Etch Durability

Akira Akimoto; Toru Seita; Yoshitaka Tsutsumi

Electron beam exposure characteristics,such as sensitivity and contrast,and durability against oxygen plasma were measured with poly(1-pheny1-2.2.2-trifluoroethyl-α-chloro-acrylate) PCLTF prepared by solution free radical polymerization. New developers were examined for this type of polymer. Using mixtures of diisobutyl ketone DIBK and isopropyl alcohol IPA (35:65),PCLTF was preciously imaged at 25pc/cm2(0.5μm lines and spaces). Moreover with use of suitable mixture of diisopropyl ketone DIPK and isopropyl alcohol (35:65),the image at 8pc/cm2(1μm lines & spaces) is also possible. PCLTF was 1.5 times the high dry etching durability of PMMA against oxygen plasma,and showed considerably high contrast and fine gaps as narrow as 0.2μm.
