摘要:
A moisture sensor includes interdigitated first and second electrodes formed in trenches A porous low-k dielectric is provided between the electrodes. The electrodes are of Cu surrounded by a barrier layer to protect the Cu from corrosion. TiN may be used as barrier layer and selectively deposited barrier material such as CoWB, MoWB or NiMoP as barrier layer.
