About Semiconductor-Related Testing

Semiconductors are materials with electrical conductivity at room temperature that falls between conductors and insulators. They are used in numerous fields such as integrated circuits, consumer electronics, communication systems, and photovoltaic power generation. As the material used in the core units of most electronic products, their quality directly affects the operation of the entire system.

Power amplifiers, as essential components in semiconductor testing systems, play a crucial role in research within the semiconductor testing field. Aigtek has compiled some past experimental cases related to semiconductor testing into a collection, hoping to be helpful to colleagues in the semiconductor field.

▼ Application of Power Amplifiers in High-Voltage and Wireless Driving of In-Capacitor LED Devices

In this experiment, inspired by the triboelectric nanogenerator (TENG), researchers proposed an in-capacitor LED device. Signals provided by a signal generator amplified by a power amplifier were used for testing and compared with the TENG output. The working mechanism of the TENG-driven LED was explained in detail, and an in-capacitor LED structure was proposed to promote the development of TENG and AC LEDs.

▼ Application of Power Amplifiers in the Study of Photoelectric Characteristics of Non-Conductor Contact μLED Devices

This experiment was based on the outstanding advantages of GaN-based micro-light-emitting diodes (μLEDs) in ultra-high-resolution displays, micro-displays, visible light communication, and solid-state lighting. A non-conductor contact μLED model was established, and corresponding devices were fabricated. For this novel μLED structure, its photoelectric characteristics under AC signal drive, such as frequency-voltage, current-voltage, and luminous intensity, as well as its working mechanism, were studied. This provides theoretical guidance for improving μLED device structures and optimizing operational modes.

▼ Application of High-Voltage Power Amplifiers in Nuclear Magnetic Resonance Oscillators

This experiment proposed a method for measuring the transverse relaxation time τ₂. By applying a frequency-swept magnetic field along the x-axis and then measuring the amplitude-frequency response curve of the magnetometer in the x-axis direction, τ₂ was obtained from the 3dB bandwidth of the amplitude-frequency response curve. Detailed and rigorous theoretical derivation based on the perturbation-iteration method was provided to demonstrate the rationality of this measurement method. Simulation and practical experiments were conducted, and the results verified the effectiveness and high accuracy of this measurement method.

▼ Application of Power Amplifiers in Research on High-Power Pulsed Electrical Energy Sources

To further improve calibration accuracy beyond traditional measurement precision calibration methods, this experiment proposed a high-precision calibration method addressing the measurement accuracy issues of high-power pulsed current measurement sensors. An experimental platform for a high-power pulsed current measurement system was built. The performance of the high-power pulsed current measurement sensor was verified through experiments, primarily focusing on its accuracy, stability, response time, and current amplitude measurement range.

▼ Application of High-Voltage Amplifiers in Research on Multi-Wavelength Interferometric Phase Synchronous Demodulation Methods

This experiment studied a multi-wavelength interferometric phase synchronous demodulation method based on laser phase discrete modulation. The Frequency Division Multiplexing (FDM) dual-wavelength interferometric phase synchronous demodulation method was analyzed via simulation and experimentally verified. The proposed FDM dual-wavelength interferometric optical path was built, and experiments were conducted including system stability tests, nanoscale displacement measurement, nanoscale stepping nonlinear error analysis, two-position displacement demodulation synchronization tests, and dynamic phase demodulation.
