SiC and GaN semiconductor components feature high power density and compact dimensions, causing heat to be concentrated within a very small chip area. The question of which thermal management solution is most widely used is often framed as a choice between four options: fans, heatsinks, thermal pads, or thermal grease. This framing requires some refinement, as these four components occupy different positions along the same heat-transfer path; in fact, most designs employ a combination of several of these elements. This article explains the role of each component, how to select thermal interface materials, and the impact of temperature on measurements.

For safer high-power DC testing, assess five protection functions: OVP, OCP, OTP, reverse-polarity protection, and short-circuit/fault protection. Together, they address abnormal voltage, current, heat, wiring, and system-fault conditions.

A battery simulation DC power supply should be selected around the device under test: required voltage, peak current, power, charge/discharge behavior, dynamic response, model fidelity, integration, and protection needs.

MBE is an epitaxy technology that enables highly precise control over crystal growth, making it particularly suitable for researching semiconductor heterostructures, high-speed transistors, semiconductor lasers, and nanomaterials.

Input overload can lead to inaccurate RF measurements and potentially damage your probe. Learn about the causes, how to identify such issues, and how to select the right Keysight N9000B, N9010B, or FieldFox signal analyzer for your needs at EMIN

A set of screwdriver bits typically contains dozens of pieces, each with a distinct shape. Every shape is designed to fit a specific type of screw recess; using the wrong bit can cause it to slip or damage the screw head—a risk that is especially high when using high-speed electric screwdrivers. This article introduces common types of electric screwdriver bits, explains how to distinguish between those that are easily confused, and outlines the key specifications to consider when making a purchase

At the Tektronix Semiconductor 2026 seminar, alongside technical presentations on semiconductor technologies, attendees had the opportunity to explore and experience live equipment demonstrations featuring the DPO1000, Keithley 4200A-SCS, MSO58B, and EA-PSB 10000 bidirectional DC power supply. Each instrument serves a different measurement purpose, illustrating key technical requirements in semiconductor research and device validation.

Engineers need to develop a deeper understanding of semiconductor physics, device operating principles, signal characteristics, and component-level testing and measurement methods.

A bidirectional power supply can emulate key battery behavior while both delivering power to and absorbing returned energy, helping engineers create repeatable laboratory tests.

A 3x current-sizing approach can provide margin for appliance startup inrush, capacitor-charging peaks, and compressor starting transients that a nameplate-current source may not sustain.
