Flow behavior at the embossing stage of nanoimprint lithography

Nanoimprint lithography (NIL) is a nanofabrication method known to be a low cost method of fabricating nano scale patterns as small as 6 nm. This study is focused on understanding physical phenomena in the embossing of nano/micro scale structures with 100 nm minimum feature size. We present the effects of capillary force and width of stamp groove on flow behavior at the embossing stage through numerical experimentation. We also compare our numerical results with previous, experimental results and discuss our results.
