초록 1. INTRODUCTION
Nanoimprinting lithography (NIL) is known as a technique for the generation of high definition nano and micrometer scale patterns. Nano and micro pattern processes are very necessary for the fabrication of commercial products such as micro-fluidics, bio-devices, flexible display and MEMS structures. NIL needs a mold to form patterns on a substrate. Conventional mold materials are fabricated by silicon, quartz, and metal. Silicon and quartz molds are easy to break. Metal molds are cost intensive and take a long time to fabricate. Alternatively, plastic molds are robust enough to imprint and inexpensive. In this paper, we fabricated plastic mold using PC(poly -carbonate) wafers and imprinted to PMMA substrate by hot embossing process.

2. EXPERIMENTAL RESULTS
AZ1518 PR(Clariant, USA) was spin-coated on a 500 nm thick 4 inch oxide wafer to have 1.5 µm thickness. Coated wafer was going on a photolithography process using a chrome mask which had 4 µm pattern width. After developing, patterned oxide wafer was dry etched using an oxide etcher(AOE, STS, England). Residual AZ1518 was removed by PR remover(Kwik Strip®, Clariant, USA). Prepared oxide wafer mold was deposited an antistiction layer using a home-made type PECVD(plasma enhanced chemical vapor deposition). PC wafer was imprinted by the oxide wafer mold using EVG520HE (EVG, Austria).
