Semiconductor testing: Solutions for research, development, and series testing

Purpose and tasks of semiconductor testing


Semiconductors are core components of modern electronic components used in power transistors, optoelectronic products, and high-frequency applications. Extensive testing is carried out to validate their functional safety, reliability, and performance under real-world conditions. Semiconductor testing includes I-V characterization, aging tests, pulse loads, and parametric testing under realistic operating conditions. For these demanding tasks, Schulz-Electronic offers a comprehensive portfolio of power supplies, electronic loads, and source measure units (SMUs) that are characterized by high precision, modularity, and automatability.

Areas of application and challenges


Semiconductor testing is carried out in many industries and areas of application, such as semiconductor development and manufacturing, power electronics (SiC, GaN, IGBT, MOSFET), optoelectronics (LEDs, lasers, photodiodes), automotive engineering, industrial electronics, telecommunications, and research.

The main challenges in electrical testing in the semiconductor industry:

  • Testing of functional parameters such as leakage currents, breakdown voltages, and threshold voltages.
  • Aging and reliability tests under extreme conditions such as high temperature, humidity, and cyclic current load (e.g., HTRB, HTGB, H3TRB).
  • I-V characteristic curve characterization of diodes, MOSFETs, IGBTs, and other power components.
  • Chip pin electroplating, where uniform coating and stable contacting are crucial.
  • Parametric tests that must measure the dynamic and static properties of semiconductor components under varying voltage and current conditions.
