ABSTRACT:
A nanoimprinting system incorporates a patterned media contact architecture to provide a uniform imprinting pressure across the target imprinting area on a disk substrate. The system leverages the unique disk substrate characteristic of an inner diameter hole by incorporating a membrane suspension, gel-pad buffering, and air cushion loading that exploits the inner diameter hole characteristics of the disk substrate. This design dramatically increases the uniformity of the pressing pressure across the target imprinting area. As a result, a simple and effective improvement of the quality of the patterns imprinted on the recording disk substrate is realized.
