Dramatic MBE Substrate Holder Effects Measured with kSA BandiT Most MBE reactors utilize a refractory metal substrate holding system (typically Mo) that attempts to minimize thermal contact with the sample while providing good IR coupling with the heater. However, when using fractional wafer sizes, sample size and loading procedures have profound impact on the actual sample temperature, even when the substrate heater TC reads the same temperature. Temperature variations of more than 60°C between 1cm x 1cm and 2cm x 2cm substrates were observed (see figure above) on an MBE reactor used for growth of GaAs related materials. Using BandiT the substrate set point can be adjusted to reach the proper growth temperature.

BandiT Runs Off With MBE! One of our long-standing kSA BandiT customers, Prof. Tom Foxon of Nottingham University (UK), was recently quoted as saying, “I believe BandiT is the most important development for MBE since RHEED oscillations.” Thanks, Tom! |
New! kSA BandiT BlackBody Temperature Monitoring Is Now Available! kSA BandiT now includes a novel BlackBody emission monitoring technology whereby the spectral radiation intensity of a sample is fit in real time to Planck’s equation to determine temperature. Direct, in-situ calibration via kSA BandiT’s band-edge technique or BandiT’s high-temperature auto-calibration routine ensures utmost accuracy. By measuring sample radiation intensity across a broad range of emission wavelengths, emisivity changes are minimized while ensuring unprecedented temperature resolution (typically better than 0.1°C). kSA BandiT BlackBody technology is compatible with all semiconductor and non-semiconductor substrates, including metal films, from 300°C on up. Please contact kSA for more details or see kSA’s new Application Note on this patent-pending technology.

kSA MOS Ultra-Scan Stress Mapping Gives Insight into Patterned Substrates The kSA MOS Ultra-Scan has been used for curvature measurements on metal lithography patterned wafers. The high resolution resulting from the patented 2D laser spot array enables the measurement of localized curvature induced by the patterned metallization process on 200mm silicon substrates. Data shown here is taken with 250µm scan resolution (above) and 50µm resolution (below) with lighter regions identified as areas of higher stress when compared with bare samples.
