Features such as bumps, pillars and/or vias can be plated best using current with either a square wave or square wave with open circuit wave form. Using the square wave or square wave with open circuit wave forms of plating current, produces features such as bumps, pillars, and vias with optimum shape and filling characteristics. Specifically, vias are filled uniformly and completely, and pillars are formed without rounded tops, bullet shape, or waist curves. In the process, the metalizing substrate is contacted with an electrolytic copper deposition composition. The deposition composition comprises a source of copper ions, an acid component selected from among an inorganic acid, an organic sulfonic acid, and mixtures thereof, an accelerator, a suppressor, a leveler, and chloride ions.

A method for forming a sensing device includes providing a first substrate. The first substrate has a first surface and a second surface opposite thereto. A sensing region is adjacent to the first surface. A temporary cover plate is provided on the second surface to cover the sensing region. The method also includes forming a redistribution layer on the second surface and electrically connected to the sensing region. The method further includes removing the temporary cover plate after the formation of the redistribution layer. The first substrate is bonded to a second substrate and a cover plate after the removal of the temporary cover plate so that the first substrate is positioned between the second substrate and the cover plate. In addition, the method includes filling an encapsulating layer between the second substrate and the cover plate to surround the first substrate.
