DARPA Organic Interconnect Characterization



Dylan Williams, Richard Chamberlin, Jerome Cheron, Sam Chitwood, Ken Willis, Brad Butler, Farhang Yazdani


We report on a study of interconnects fabricated on organic and silicon interposers used to connect state-of-the art digital, analog and RF chiplets commissioned by the U.S. Defense Advanced Research Projects Agency (DARPA). The interconnects were characterized with state-of- the-art on-wafer measurement methods developed at the National Institute of Standards and Technology (NIST) and then simulated with the Cadence Sigrity* simulation software package. The two-port, four-port and eight-port measurements and calibrations were performed to frequencies as high as 110 GHz using custom on-wafer calibrations to improve accuracy. We discuss the measurement and simulation methodologies and present detailed comparisons of the measurement and simulation results.
