Abstract: Substantially transparent conductor layers in touch sensing systems may be formed by forming a barrier layer between an organic layer and a substantially transparent conductive layer. For example, a barrier layer can be formed over the organic layer, and the transparent conductor layer can be formed over the barrier layer. The barrier layer can reduce or prevent outgassing of the organic layer, to help increase the quality of the transparent conductor layer. In another example, a combination layer of two different types of a transparent conductor may be formed over the organic layer by forming a barrier layer of the transparent conductor, and forming a second layer of the transparent conductor on the barrier layer. Outgassing that can occur when forming the barrier layer can cause the transparent conductor of the barrier layer to be of lower-quality, but can result in a higher-quality transparent conductor of the second layer.
