Abstract:
A method for fabricating a thin film transistor includes printing source, drain and channel regions on a passivated transparent substrate, forming a gate dielectric over the channel region and forming a gate conductor over the gate dielectric. A permanent antireflective coating is deposited over the source region, drain region and gate electrode, and an interlevel dielectric layer is formed over the permanent antireflective coating. Openings in the permanent antireflective coating and the interlevel dielectric layer are formed to provide contact holes to the source region, drain region and gate electrode. A conductor is deposited in the contact holes to electrically connect to the source region, drain region and gate electrode. Thin film transistor devices and other methods are also disclosed.
