Abstract

The Interdigital Capacitors (IDCs) are integrated circuits within metal fingers electrode for measurement of specific properties. A new model has been carried out for fabrication and characterization of silver and copper thin film electrode of IDCs for the measurement of crude oil permittivity. Thin film electrode was fabricated by Direct Current (DC) Magnetron Sputtering method using silver and copper target on Flame Resistant (FR)-4 Printed Circuit Board (PCB). The electrode configuration was composed in seven designs.The experimental results show that, IDCs thin film has a great potential to determine the permittivity of crude oil.
