Abstract
A method of fabricating a glassy carbon film is described. The method includes forming a soluble layer on a substrate, forming a lift-off stack that includes a lift-off mask layer and a hard-mask layer, and forming a pattern in the lift-off stack to expose a portion of the soluble layer. The exposed portions of the soluble layer are removed to expose a portion of the substrate. A carbon material is over the exposed portion of the substrate. The soluble layer is dissolved in a solvent, and the lift-off stack is lifted-off.
