The Wafer Profiler CVP21 is a handy tool to measure doping profiles in semiconductor layers by Electrochemical Capacitance Voltage Profiling (ECV-Profiling, CV-Profiling) in semiconductor research or production. This ECV Profiler (CV-Profiler, C-V-Profiler) furthermore is a very good choice to analyze or develop strategies for Photo-Electrochemical Wet Etching (PEC-Etching) of semiconductors

The wafer measurement instrument offering the best available calibrated analysis of carrier recombination lifetime. Fully compliant with SEMI Standard PV-13. The WCT-120 is an affordable, tabletop silicon lifetime and wafer metrology system, suitable for both device research and industrial process control. The WCT-120MX is optimized for 230mm wafer measurements. The WCT-120 instruments utilize both the QSSPC and transient photoconductance decay techniques to measure the lifetimes of wafers in the range of 10ns to greater than 10ms. The QSSPC technique is ideal for monitoring multicrystalline wafers, dopant diffusions, and low lifetime samples. The transient photoconductance decay technique is ideal for monitoring high lifetime samples at various processing steps. The WCT-120 lifetime measurement also yields the implied open-circuit voltage (versus illumination) curve, which is comparable to an l-V curve at each stage of a solar cell process.

Sinton少子寿命测试仪 BCT400/BLS-1 不用接触就可以简单准确地测量原生或成型硅块的真实寿命。与半导体工业标准PV(光伏）－13相符合。

TLM-SCAN+ Contact resistivity and more This compact instrument measures contact resistivity, finger line resistance, finger width, and finger height of a finished solar cell or on test structures. Motorized in all axes it is capable of creating maps of all these methods by pushing a single button. Four point probe heads for measuring the sheet resistance of thin diffused layers and resistivity of wafers make the TLM-SCAN+ a low-cost yet fast and high-quality four-point-probe mapper.
