Abstract
A layered structure comprises a variable wettability layer including a material that changes a critical surface tension in response to energy provided thereto, the wettability changing layer including at least a high surface energy part of large critical surface tension and a low surface energy part of low critical surface tension, a conductive layer formed on the variable wettability layer at the high surface energy tension part, and a semiconductor layer formed on the variable wettability layer at the low surface energy part.
