Abstract
A method of improving the electrical conductivity of transparent conducting lines ( ) carried on a substrate ( ), particularly address lines on the active plate for a pixellated device such as an active matrix liquid crystal display or the like fabricated using a low mask count process, involves forming the lines on the substrate from a deposited layer of transparent conducting material ( ), e.g. ITO, and provided on their upper surface with a covering layer ( ) extending from at least one end ( ) and partially covering the surface, and then performing an electroplating operation to plate the lines ( ) with a plating potential being applied at that end. The covering layer ( ) assists in achieving a more uniform plated layer ( ) along the length of the line. The covering layer preferably comprises photoresist defined by selective patterning and partial etching of a deposited photoresist layer ( ) used for patterning the transparent layer ( ). In a pixellated device, pixel electrodes ( ) are also defined from the transparent layer.
