Abstract:
Electroplating methods enable the plating of photoresist defined features which have substantially uniform morphology. The electroplating methods include copper electroplating baths with reaction products of ±-amino acids and bisepoxides to electroplate the photoresist defined features. Such features include pillars, bond pads and line space features.

Abstract:
To provide a copper foil that the transmission loss is favorably controlled even when the copper foil is used in a high-frequency circuit board and that adhesion to a resin is favorable. A copper foil including a roughened layer, and the roughened layer includes a primary particle layer, a surface roughness Ra of a surface on the side of the primary particle layer is 0.12 µm or less, and the average particle size of primary particles of the primary particle layer is 0.10 to 0.25 µm.
