Patent ID: 7612455

Claim:
A layered structure comprising: a variable wettability layer including a material that changes a critical surface tension in response to ultraviolet radiation of a wavelength of 200 nm 300 nm provided thereto, said variable wettability layer comprising at least a high surface energy part of larger critical surface tension and a low surface energy part of lower critical surface tension; a conductive layer formed on said variable wettability layer at said high surface energy tension part; a semiconductor layer formed on said variable wettability layer at said low surface energy part; wherein there exists a difference of critical surface tension in said variable wettability layer between said low surface energy part and said high surface energy part; said variable wettability layer comprising at least a first material and a second material, said first material having an electrical insulation higher than the second material, and said second material having a higher change of said critical surface tension in response to energy provided thereto than the first material; and said variable wettability layer having a layered structure comprising, 1) a first layer of said first material and 2) a second layer formed over said first layer by said second material, said variable wettability layer being a material selected from the group consisting of the following chemical formulae (1)-(5):
