GaAs Substrate Thickness Measurement
Semiconductor Gaas Substrate Thickness Measurement Thickness Description Measuring Thickness of Wafers with Different Chemistries Introduction:  Silicon wafers are ordinarily highly conductive and easy to measure with standard capacitive displacement sensors (See MTI's Proforma 300i). Measuring the thickness of GaAs wafers that have high bulk resistivity (>10k Ohm/cm) is a little more difficult because the wafers act as non-conductive insulators in a capacitive sensor's measuring field. Fortunately, MTI has a solution to this problem. Solution:  It’s possible to measure the thickness and TTV of high resistivity semiconducting wafers (like GaAs) using non-contact [...]
Photolithography Using Capacitance Sensors
Photolithography Using Capacitance Sensors Semiconductor Photolithography Using Capacitance Sensors Positioning Description When it comes to photolithography, how accurate are our sensors? Accurate enough to measure this: ​   Photo by D. Carr and H. Craighead, Cornell The world's smallest guitar is 10 micrometers long -- about the size of a single cell -- with six strings each about 50 nanometers, or 100 atoms, wide. Made by Cornell University researchers from crystalline silicon, it demonstrates a new technology for a new generation of electromechanical devices. Even the world’s smallest guitar’s 2 micron [...]

The Basics of Insulation Resistance Testing and Why It’s So Important
In high-voltage and industrial electrical systems, insulation is the first line of defense against equipment failure, electrical shock, and system downtime. Over time, insulation materials are subjected to electrical stress, temperature variation, humidity, and mechanical wear — all of which degrade performance and increase leakage current. That’s where the insulation resistance test comes in. Whether you’re maintaining high-voltage equipment, troubleshooting faults, or ensuring compliance, measuring insulation resistance is a critical step in identifying early signs of wear, aging, or potential failure. With the right equipment and understanding, you can prevent shocks, avoid short circuits, and extend the lifespan of [...]
Whitepaper: Three Vibration/Balancing Solutions for the Aviation Industry
Three Vibration/Balancing Solutions for the Aviation Industry MTI Instruments Offers a Variety of Solutions for Commercial, Regional & Military Jet Engine Balancing Applications Introduction Throughout the aviation industry, whether commercial or military, jet engine vibration is an everyday concern. Maintenance, repair, and overhaul crews worldwide are tasked with monitoring aircraft engine vibration to ensure flight safety and efficient service. Gone unchecked, jet engine vibration can be the catalyst for any number of problems, from minor annoyances such as cabin noise to undue parts wear. In the most severe cases, an out-of-balance turbine could lead to catastrophic failure [...]
New Video from MTI! Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing
Closed-loop System to Monitor and Control Conductive Film Thickness During Manufacturing This animation demonstrates how Accumeasure with capacitance probes can be used as a solution to measure and control conductive film thickness in a production line where these measurements can be fed back to a controller which adjusts the roller(s) to increase or decrease the gap to keep the film’s thickness within specification. The MTI Instruments Capacitive system has greater than 100 nm resolution and 1um accuracy. This solution is appropriate for measuring the following: EV battery plate thickness Non-woven conductive material thickness Conductive film thickness Roll-to-roll conductive [...]
Safety Recommendations for Setting Up a Hipot Testing Workstation
Hipot testing is necessary for ensuring the electrical safety compliance of electronic equipment. However, testing the voltage on commercial equipment can result in errors and even death if the operators have not been properly trained on the importance of establishing a safe testing environment. Before any tests are performed, operators should be thoroughly trained on the effects of electrical currents on the human body, the importance of safety interlocks, and how to program the necessary tests and store them in memory. If operators lack the appropriate training, setting up a safe hipot testing workstation would be for naught. After prioritizing [...]
