Abstract
This invention discloses that photolithography can be made compatible with the production of electronic devices containing sensitive materials, if the sensitive materials are over-coated with an ultra-thin layer of non-reactive materials (e.g. inorganic oxides) before undergoing photolithographic patterning. This protecting layer isolates the sensitive materials from solvents and etching reactants used in photolithographic patterning, and does not need to be removed from the sensitive materials after patterning is completed. This invention enables photolithography to be applied to the production of electronic devices containing sensitive materials, facilitating the development of commercially viable production processes for these devices.
