THE FABRICATING METHOD OF PATTENED SAPPHIRE SUBSTRATE USING IMPRINTING

摘要

A method for fabricating a sapphire substrate patterned by using an imprinting process is provided to improve efficiency of illuminance by using the sapphire substrate with various surface patterns as a reflector through difference of a refractive index. A molder with an engraved pattern is manufactured. The polymer resin is laminated on a sapphire substrate(20). The molder with the engraved pattern is covered on the sapphire substrate laminated with the polymer resin. When the molder is covered on the sapphire substrate, the polymer resin is cured by applying the heat or UV after giving the pressure. The sapphire substrate and the molder are separated. The molder is made by using at least one of silicon, polymer resin, nickel, and silica or more. The polymer resin is thermosetting polymer resin or UV curable polymer resin.
