The IQ Aligner UV-NIL System allows for micromolding and nanoimprinting processes with stamps and wafers from 150 mm to 300 mm diameters and is well suited for highly parallel fabrication of polymeric microlenses. Starting out from soft working stamps replicated from wafer-size master stamps, the system offers hybrid and monolithic microlens molding processes that can be easily adapted to various material combinations for working stamp and microlens materials. In addition, EV Group offers a qualified microlens molding process, including all relevant material know-how. Uniform contact force for high-yield large-area printing is provided by EV Group's proprietary chuck design. Configurations include release mechanisms for stamps from imprinted substrates.
