Abstract:
The present invention relates to a flexible copper thin film laminated film treating method, which is capable of securing high dimensional stability, and a flexible copper thin film laminated film obtained by using the same. The flexible copper thin film laminated film treating method, which is capable of securing high dimensional stability in a manufacturing process of flexible copper thin film laminated films, of the present invention comprises the following steps of: successively depositing a tie layer and a seed layer on a high polymer polyamide film with excellent flexibility and thermal resistance by using a sputtering method; laminating a copper layer thereon by using a plating method; heat-treating the manufactured flexible copper thin film laminated films at 40-100 in a vacuum tank in a decompressed state within the range of 10-4 or 10-1 Torr by using an infrared (IR) source; and vacuum-heat-treating the manufactured flexible copper thin film laminated films for more than one hour. The flexible copper thin film laminated film treating method, which is capable of securing the high dimensional stability in the manufacturing process of flexible copper thin film laminated films, of the present invention solves problems which generate the defections of old patterning and bonding by performing heat-treatment under specific conditions; prevents the formation of oxides in a vacuum state; and has excellent bonding power and etching properties by improving adhesive force by minimizing changing stress.
Abstract:
The present invention relates to an electroplating method for deposition of uniform thickness to form a uniform plating layer by shielding an anode surface to deposit a selective or uniform plating layer. The electroplating method for deposition of uniform thickness is capable of partially shielding the anode surface with plating fluid and a shielding plate to disturb the movement of ions, thus plating an object being plated to a desired thickness. The thickness of the plating layer can be selectively adjusted or formed to be uniform by using the adjustment, thus providing a very useful industrial technique for forming a plating layer useful for refined patterning and thin film formation.
