This paper proposes a selective electrodeposition process that uses laser masking and a DC voltage. Selective electrodeposition using laser masking and a DC voltage is more efficient than that using laser masking and a pulse voltage. In other words, electrodeposition with a DC voltage allows for precise selective deposition without the limitation of the deposition region. Also, a selective electrodeposition method that uses laser masking and DC voltage can reduce the electrodeposition time. The characteristics of a copper layer deposited by laser masking and DC voltage were examined under various conditions. A selective copper layer with various micro patterns of $2{\mu}m$ thickness was successfully fabricated.
