Abstract
We propose the new fabrication method of a 70 nm half-pitch wire grid polarizer with high performance using magnetic soft mold. The device is a form of aluminium gratings on a PET(Polyethylene phthalate) substrate whose size of $3cm{\times}3cm$ is compatible with a TFT_LCD(Tin Flat Transistor Liquid Crystal Display) panel. A magnetic soft mold with a pitch of 70 nm is fabricated using two-step replication method. As a result, we get a NWGP pattern which has 70.39 nm line width, 64.76 nm depth, 140.78 nm pitch, on substrate. The maximum and minimum transmittances of the NWGP at 800 nm are 75% and 10%, respectively. This work demonstrates a unique cost-effective solution for nanopatterning requirements in consumer electronics components.
