Claim Text:
1. A method of manufacturing a metal wiring buried flexible substrate by using a plasma comprising: pre-treating a substrate by irradiating the plasma on the surface of the substrate (Step 1), the pre-treating by plasma irradiation changing the hydrophilicity of the substrate such that the pre-treated substrate has a contact angle between about 45 degrees and about 150 degrees with respect to water; forming a metal wiring on the pre-treated substrate in Step 1 (Step 2); forming a metal wiring buried polymer layer by coating a curable polymer on the substrate including the metal wiring formed thereon in Step 2 and curing (Step 3); and separating the polymer layer formed in Step 3 from the substrate in Step 1 (Step 4) by solely applying a physical force to remove the polymer layer comprising the buried metal wiring from the substrate.
