Crystal Ion Slicing (CIS)

CIS (Crystal ion slicing) is a novel technology to fabricate mesoscopically thin films. Utilizing recent ion implantation engineering, a sacrificial layer is introduced into a bulk material at controled depth. Either wet etching or thermal treatment can slice a thin film from the bulk.
