Popis: The so-called 3ω measurement technique (transient hot wire method) was established to determine the thermal conductivity of thin films. Measurements of standard substrates and films validate the found thermal conductivity values and agree with published, commonly accepted values. The method was successfully applied to determine the thermal conductivity of porous low-k dielectric materials using special test structure fabrication. The thermal conductivity of the porous low-k dielectrics thus measured is only between 7 and 13% of the thermal conductivity of thermally grown silicon dioxide.
