The semiconductor curve tracer market is rapidly growing and is expected to reach a size of 179 million USD by 2026.
What is a semiconductor curve tracer? A semiconductor curve tracer is an electronic measurement device that applies controlled direct current voltage and current, stepped or sweeping signals, pulse signals, etc., to semiconductor devices and measures their electrical responses to obtain current-voltage (I-V) characteristic curves and various device parameters. It is used for the evaluation of diodes, bipolar transistors, MOSFETs, IGBTs, thyristors, as well as SiC and GaN power devices, power modules, RF transistors, and devices on wafers. Global market size of semiconductor curve tracers According to the latest research report published by Global Reports titled "Global Market Size, Share, Company Rankings, Sales, and Demand Trend Forecast for Semiconductor Curve Tracers (2026-2032)," the semiconductor curve tracer market is advancing in the sophistication of evaluation and analysis devices, driven by the high performance of power semiconductors and the proliferation of wide bandgap materials. The global market size is expected to expand from approximately 169 million USD in 2025 to about 179 million USD in 2026, with an average annual growth rate (CAGR) of 6.4% from 2026 to 2032, reaching approximately 259 million USD by 2032.

basic information
Functions and Product Configuration of Semiconductor Curve Tracers Traditional semiconductor curve tracers are devices that integrate a sweep power supply, current and voltage measurement circuits, step signal application functions to bases and gates, test fixtures, and display functions. In recent years, their applications have expanded to modular systems that combine source measure units (SMUs) and analysis software, as well as semiconductor parameter analysis devices equipped with high-voltage and high-current pulse sources. Evaluation criteria go beyond merely confirming output characteristics and transfer characteristics. There is a demand for accommodating a variety of measurements, including leakage current, breakdown voltage, threshold voltage, on-resistance, temperature dependence, reliability evaluation, failure analysis, and device model extraction. In product selection, maximum voltage and current, measurement limits for small currents, pulse width, measurement accuracy, sampling speed, number of channels, support for four-terminal measurements, safety mechanisms, and level of automation are important comparative indicators.

Applications/Examples of results
New Demand Created by Measurement Technology for SiC and GaN The growth of semiconductor curve tracers is supported by the characterization of next-generation power semiconductors. While SiC and GaN can handle high voltage and high-speed switching, challenges arise in detecting minute leakage currents during measurement, ensuring safety under high voltage application, and suppressing errors caused by parasitic components in wiring. In devices that handle high voltage and large currents, features such as interlock-equipped fixtures, temperature control, and pulse waveform verification are also important. For example, the CS-8000 series from GRAPHTEC IWATSU boasts measurement capabilities of up to 5 kV and 2 kA, along with a current measurement resolution of 250 fA and support for wafer measurements. Such products are concrete examples of the evaluation demand for power semiconductors that is difficult to meet with conventional general-purpose measuring instruments.
