  • Method of forming copper film on Mo/SUS flexible substrate
    Patent number: 9281094
    Abstract: This invention relates to a method of forming a copper film on a Mo/SUS flexible substrate, which enables the copper film to be uniformly formed on the Mo/SUS flexible substrate in a short period of time by applying current and in which the copper film becomes thicker in proportion to an increase in a concentration of a copper precursor aqueous solution or in a current density.
    Type: Grant
