Plasmonic array was fabricated using nanoimprint technology. First, silicon mold consisting of a periodic square array was fabricated using silicon deep etching. Samco silicon DRIE system at Kyoto University was used for the mold fabrication. Then, Samco ICP etch system was used for pattern transfer by aluminum dry etching over photoresist pattern fabricated by the nanoimprint process.
