Lear, Dielectric Characteristics of Spin-coated Dielectric Films Using On-wafer Parallel-plate Capacitors at Microwave Frequencies, IEEE Transactions on Dielectrics and Electrical Insulation 12, no. 6 (December 2005): 1151-1161.http://hdl.handle.net/10217/822Dielectric properties of spin-coated dielectric insulators suitable for high-speed device fabrication are investigated. Complex dielectric permittivities and tangential losses of two polyimides, bisbenzocyclobutene (BCB), and a spin-on-glass (SOG) were extracted from the measured microwave reflection coefficient, S11, of parallel-plate capacitors over a frequency range of 50 MHz to 40 GHz. A model for the dielectric permittivity as a function of frequency is developed based on measured data with a minimum square error of less than 10-4 between measured and modeled microwave reflection coefficients. A circuit model for the pad capacitance is obtained based on geometrical and physical considerations. The relationship between the dielectric loss and its thickness is considered. Experimental results are fitted to Debye and Cole-Cole models.born digitalarticleseng©2005 IEEE.Copyright and other restrictions may apply.
