Abstract
A method of manufacturing an electrical device, comprising: forming a patterned inorganic liftoff layer to expose a target electrode site on a softening polymer layer, depositing an electrode layer on the inorganic liftoff layer and on the exposed target electrode site, and removing the inorganic liftoff layer by a horizontal liftoff etch to leave the electrode layer on the exposed target electrode site.
