Resists from Hyperbranched Polyesters for Micro-optics
Abstract:
Three-component photoresists were prepared from hyperbranched polyester,multifunctional acrylate monomer and photoinitiator.The hyperbranched resin had -COOH,-OH and methacryloxy groups at their chain ends.The dried resist on glass substrate showed an H~HB pencil hardness.A high sensitivity with E0~5.5×10-3 J/cm2 and a high contrast with γ~8 were obtained for the resist exposed with a mixed UV light and developed with TMAH aqueous solution.Sensitivity and contrast upon UV exposure were tunable by development solution and the amount of photoinitiator.The resist exhibited a unique linear relationship between exposure energy and etching depth.This property provides a controlling of surface profile of micro optical elements fabricated with photoresists.Microlens arrays(200 μm×200 μm) were prepared from these photoresists with a moving-mask.
