  • Nano-twinned crystal film prepared by water/alcohol-soluble organic additives and method of fabricating the same
    Patent number: 11578417
    Abstract: A nano-twinned crystal film and a method thereof are disclosed. The method of fabricating a nano-twinned crystal film includes utilizing an electrolyte solution including copper salt, acid, and a water or alcohol-soluble organic additive, and performing electrodeposition, under conditions of a current density of 20˜100 mA/cm2, a voltage of 0.2˜1.0V, and a cathode-anode distance of 10˜300 mm, to form the nano-twinned crystal film on a surface at the cathode. The nano-twinned crystal film formed by the method includes a plurality of nano-twinned copper grains and a region of random crystal phases between some of adjacent nano-twinned copper grains, wherein at least some of the nano-twinned copper grains have a pillar cap configuration with a wide top and a narrow bottom.
