Abstract: A capacitive touch sensitive device includes a matrix of pads patterned in a first electrically conductive material on a substrate. Horizontally adjacent pads within each even row of the matrix are electrically coupled to one another via channels to form a plurality of horizontally arranged electrodes. Insulators are positioned over respective channels. Conductive links are formed over respective insulators and are configured to electrically couple vertically adjacent pads between odd rows of the matrix to form a plurality of vertically arranged electrodes. The dimensions of the channels and the conductive links are configured such that an RC time-constant (RCtc) of each of the vertically arranged electrodes substantially matches an RCtc of each of the horizontally arranged electrodes.
