Preparation and Properties of a New Thick Film System

[摘要] Work has been carried out to develop a new ruthenium oxide based thick film resistor whose resistance isindependent of the contact area of the conductor to the resistor. Such a resistor can then be combined with alow cost silver conductor.It has been found that such a resistor can be made by doping a ruthenium oxide based thick film resistorwith up to several percent of gold. With such a material it is possible to use silver or palladium silver(containing only very small amounts of palladium) as an electrode material and very few interactions havebeen found to occur between the resistor and electrode. Such a gold doped ruthenium oxide thick film resistorusing silver electrodes has some major advantages as follows:-1. The resistor size can be made much smaller than normal.2. The design of a thick film hybrid circuit becomes easier.3. The resistor cost can be reduced.
