Resistance measurements can be performed in an environment of -180℃. Measurements can also be taken while changing the temperature.
What happens at the contact point during electrical measurements? How does the contact resistance change over time? What is the temperature rise when a large current, such as 400A, is flowing? What is the contact resistance value in a high-temperature environment of 300°C? By conducting actual measurements, it is possible to quantify what is really happening. Additionally, by combining several types of devices, we can approach measurements that are closer to real-world conditions. We are also accepting requests for visits at any time.

SRA：Spreading Resistance Analysis
SRA is a method that involves diagonally polishing the measurement sample, making contact with two probes on the polished surface, and measuring the spreading resistance. It is also referred to as SRP (Spreading Resistance Profiling). - It is possible to determine the conductivity type (p-type/n-type). - It allows for the evaluation of carrier concentration distribution in the depth direction. - It can analyze a wide range of carrier concentrations from approximately 1E12 to 2E20 /cm3. - It is capable of measuring patterned samples larger than approximately 20μm × 100μm. - By combining SRA with SIMS for evaluation, it is possible to assess the activation rate.
SRA: Spread Resistance Measurement Method
1. Measure the spreading resistance (Ω) directly beneath the surface of the sample that has been polished at an angle by contacting two probes. 2. Create a calibration curve from the measurements of the standard sample and use it to convert the resistance to resistivity (Ω·cm). Additionally, perform distribution corrections as needed through volume correction. *) The calibration curve varies depending on the conductivity type (p-type/n-type) and the surface orientation. 3. Use the relationship between resistivity and carrier concentration*) to calculate the carrier concentration (/cm³).
