| Research Abstract |
We propose a novel nano thickness inspection method of residual layer film of nanoimprint lithography, allowing nondestructive evaluation of residual layer thickness. In the proposed method, we applied near-field optical enhancement of a fine metal tip as a high spatial resolution measurement probe, with which we can get near-field optical response generated by dynamic interaction of the tip, thin residual layer film and a Si substrate. By performing theoretical analyses based on finite-difference time-domain method and fundamental experiments using a newly developed near-field optical response detection system, we verified the feasibility of the proposed method.
