Abstract
A circuit board may include an insulating layer; a circuit pattern disposed above the top surface of or below the bottom surface of the insulating layer; and a buffer layer disposed between the insulating layer and the circuit pattern, the buffer layer comprising carbon atoms, nitrogen atoms, oxygen atoms, silicon atoms, sulfur atoms, and metal atoms. The ratio of the carbon atoms to the metal atoms ((carbon atom/copper atom)*100) is within a range of 5-7; the ratio of the nitrogen atoms to the metal atoms ((nitrogen atom/copper atom)*100) is within a range of 1.5-7; the ratio of the oxygen atoms to the metal atoms ((oxygen atom/copper atom)*100) is within a range of 1.1-1.9; and the ratio of the silicon atoms to the metal atoms ((silicon atom/copper atom)*100) is within a range of 0.5-0.9; and the ratio of the sulfur atoms to the metal atoms ((sulfur atom/copper atom)*100) is within a range of 0.5-1.5.
