Abstract
The knowledge of thermal properties of materials is
important for many fields of technology such as thermal
management for microelectronics, for the selection of
interface or filler materials as well as for thermal
simulations. We developed, designed and fabricated a
characterization chip for the measurement of the thermal
conductivity and diffusivity of, e.g., pastes, gels,
fluids, polymers and bulk samples. The measurement
principle is based on an extension of the 3-omega method.
For the traditional 3-omega method a thin metal heater
line must be deposited on top of the sample, which is
often impractical and even impossible for non-solid
samples or samples with rough surfaces. We are using an
extension of the 3-omega method, which also allows to
measure the thermal properties of such materials for
which the traditional 3-omega method is not applicable.
In our measurement system, the sample can be simply put
onto a chip in which the 3-omega heater is already
integrated. Due to the use of through-glass vias, the
complete top side of the chip is available for the sample
deposition. In this work, the design and fabrication of
the chips and measurements of the thermal properties of
reference samples are presented.
