Understanding Semiconductor Wafer Stress: A Practical Guide to Thin-Film Stress, Wafer Curvature Measurement & Process Control
Introduction Every semiconductor device begins with a nearly perfect wafer. Yet throughout fabrication, that wafer is repeatedly transformed by dozens of manufacturing processes including thin-film deposition, oxidation, implantation, annealing, polishing, and packaging. While each process is designed to modify the electrical properties of the device, it also alters something far less visible—its mechanical condition. The addition of every thin film introduces internal mechanical forces that can subtly change the shape of the wafer. These changes, often measured in only a few micrometers across a 200 mm or 300 mm substrate, may appear insignificant. However, as semiconductor devices continue to [...]

Compliance Testing of Harmonic Current Emissions According to IEC61000-3-2 and IEC61000-3-12.
Compliance Testing of Harmonic Current Emissions According to IEC61000-3-2 and IEC61000-3-12. Using the Vitrek PA900 Precision Harmonic Power Analyzer Introduction Compliance with electromagnetic compatibility (EMC) standards is mandatory for electrical and electronic equipment sold in many global markets. Among these, the IEC61000-3-2 and IEC61000-3-12 standards specify limits for harmonic current emissions of equipment connected to low-voltage public supply systems. These limits ensure that individual devices do not contribute excessively to harmonic distortion on the power grid, which can lead to overheating in transformers, nuisance tripping of breakers, and interference with other equipment. The Vitrek PA900 Precision Power [...]
High Precision Portable Signal Generators and Calibrators: Everything You Need to Know
High precision portable signal generators are portable electronic devices that generate highly precise signals for testing, system calibration, sensor simulation, troubleshooting, and monitoring. Unlike the benchtop signal generators that are used in laboratories, these hand-held portable devices are designed to be used in the field. The best high precision portable signal generators are also rugged and NIST traceable, meaning that their manufacturer calibrates them to standards from the National Institute of Standards and Technology (NIST). In terms of cost, high precision portable signal generators are more expensive than less precise, lower-end devices that can be held in the hand; [...]

Precision Control in Semiconductor Wafer Lapping
Application Overview Wafer lapping is a critical semiconductor thinning process that demands tight control to avoid over-removal of material, which can lead to costly yield loss. This application note details how MTI Instruments’ Accumeasure™ capacitive sensing technology enabled precise, real-time displacement and thickness measurement during lapping operations, ensuring consistent wafer quality. Challenge During lapping, wafers are thinned from the backside using a rotating abrasive surface. As the process proceeds, precise feedback is essential to monitor how much material is removed and to determine the wafer's final thickness. Traditional mechanical methods or visual inspections are not sensitive or fast enough [...]

Introduction Figure 1. Examples of photo-mulitiplier tubes, or PMTs (Photo courtesy of Hamamatsu). An important category of experimental physics is nuclear and particle physics, a near synonym for high-energy physics. A broad range of experiments in this domain are classed as scattering experiments in which an incident particle hits a target and the resulting scattered particles are studied. Scattering processes can involve the creation or annihilation of particles. The modern approach to studying scattered particles is to employ particle detectors, devices that detect individual particles impinging upon them. This paper provides an overview of typical instruments [...]
