Characterization and modelling up to sub THz

Sub-mm-wave frequency circuits are very compact in size due to the wavelength reduction at increased frequency (e.g., a /4 coplanar transmission line integrated on silicon dioxide reduces from ~1.6 mm at 30GHz to ~160 um at 300GHz) and therefore have very small parasitic components. Consequently, small inaccuracies in the exact location of reference planes or deviations due to the systematic errors of the measurement setup can significantly impact the modeling of the device under test (DUT). Moreover the circuit performance at sub-mm-wave is pushing the limits of the technology, leaving no headroom or design margins. For this reason, the transistor models need to be accurately verified and their parameters properly adjusted to represent the sub-mm-wave behavior of the fabricated devices including electrothermal effects, large-signal and distortion behavior, non-quasi-static effects, and correlated noise. This requires on-wafer measurement capability that spans from DC to the mm-wave and sub-mm-wave frequency ranges. Consequently, there is a great need for reliable measurements of passive devices and high-speed transistors intended for sub-mm-wave frequencies at this moment.
