basic information
The thermal diffusivity of "Si wafers," which are essential materials for semiconductors, can be measured. We would like to introduce the measurements of Si wafers that we uniquely obtained. The measurements were taken for the following five types. Each has different p-type/n-type characteristics and doping amounts. 1. Silicon <0.02Ωcm / P, Low, 100 2. Silicon >1000Ωcm / P, High, 111 3. Silicon <0.02Ωcm / N, Low, 100 4. Silicon <0.02Ωcm / N, Low, 111 5. Silicon >1000Ωcm / N, High, 111 When measured with our ThermoWave Analyzer TA, Thermal conductivity (thermal diffusivity) 1. Approximately 120W/mK (74mm²/s) 2. Approximately 140W/mK (87mm²/s) 3. Approximately 120W/mK (76mm²/s) 4. Approximately 120W/mK (75mm²/s) 5. Approximately 140W/mK (87mm²/s) * The thermal conductivity is calculated from the measured values of thermal diffusivity and the literature values of specific heat and density. In terms of thermal conductivity, there does not seem to be a significant difference between p-type and n-type. However, there appears to be a difference between high and low.
