Using Capacitance Sensors for Non-Conductive Material Measurement
Non-Conductive Material Measurement with Capacitance Sensors Capacitance sensors are non-contact devices that can be used to obtain position, thickness, and dynamic measurements with a high degree of precision, accuracy, and resolution. Capacitive measurement is used with electrically-conductive materials such as metals but can also be used to measure non-conductive materials such as glass, sapphire, and many plastics. Even if a non-conductive material is relatively inexpensive (such as closed cell foam), manufacturers want to avoid errors that can result in significant waste across high volumes. Importantly, capacitance measurement is also used with semi-insulating materials such as gallium arsenide (GaAs) and [...]
Semiconductor Wafer Lapping and Displacement Measurement
Semiconductor Wafer Lapping and Displacement Measurement Semiconductor Semiconductor Wafer Manufacturing Displacement Description Semiconductor Wafer Lapping and Displacement Measurement This application note explains how MTI’s Accumeasure technology was used with a lapping machine to measure displacement (wafer material removal) and determine the new semiconductor wafer thickness. Changes in electrical capacitance (displacement) were measured and then directly converted into a 24-bit digital reading to obtain precise digital thickness measurements. During lapping, a wafer of known start thickness is placed on a rotary lapping table. The backside of the wafer faces downward and toward [...]

Why Demand for SiC Wafers is Soaring and Durable
Silicon carbide (SiC) wafers are in high demand, particularly in high-temperature applications. Silicon carbide (SiC), a semiconductor material made of both silicon and carbon, can withstand extreme temperatures of up to 2700°C. Often referred to as carborundum, SiC’s unique properties also make it a key material in non-electronic applications such as bulletproof vests, extrusion dies, sandpaper, and high-performance disc brakes. In the electronics industry, SiC wafers are crucial for devices operating under high temperatures, high voltages, or both. For example, they are used in electric vehicle (EV) power electronics, 5G communication systems, and LED technology, making SiC a material [...]
Wafer Stress Analysis Using the 300iSA
Wafer Stress Analysis Using MTI Instruments Proforma 300iSA Wafer processing involves several stages that can lead to mechanical changes in the wafer structure. These changes, or stresses, may result in deformities, making the wafer either unusable or only marginally usable. To evaluate these stresses and determine the wafer's quality, wafer stress measurement is essential. The Proforma 300iSA wafer characterization tool offers a powerful solution for wafer stress analysis. It allows for the analysis of a wafer both before and after processing. By comparing these two states, the Proforma 300iSA effectively evaluates the wafer's stress levels and mechanical alterations, providing [...]
Weathering the storm: Keys to resiliency in MRO
Weathering the storm: Keys to resiliency in MRO By Ken Ameika It’s no secret that COVID-19 has adversely affected the airline industry, and consequently the MRO and test cell markets. But the impacts are nuanced. Commercial aircraft utilization is way down; meanwhile, freight carrier business is expanding markedly. Operators are spending less; but they still have needs, which often require quick turnaround. It’s been hard for many. But there’s good news: COVID provided lessons that we can all use to make our businesses, or our careers, more resilient to the next major disruption. Diversify Your Business Commercial passenger traffic—or [...]
Capacitance Probes vs. Strain Gauges in Piezo Flexure Stages
Capacitance probes with pico-positioning sensors can be embedded in piezo flexure stages. With minor mounting modifications, these non-contact probes provide significantly greater accuracy than strain gauges. Piezo flexure stages are positioning devices with a high degree of resolution. These motion stages contain a piezoelectric actuator that converts an electrical signal into displacement based on the reverse piezoelectric effect, which is the ability of a piezo electric material to elongate when a voltage is applied. When a voltage (e.g., 0-150 VDC) is applied to the actuator, the stage moves in proportion to the applied voltage. Yet, the exact position remains [...]

CMP and Capacitance-Based Semiconductor Wafer Measurement
Chemical mechanical polishing (CMP) uses chemical oxidation and mechanical abrasion to selectively remove material from semiconductor wafers in order to achieve very high levels of planarity. The planarity, or flatness, of these wafers is important for optical lithography, a microfabrication technique that produces integrated circuits (ICs) by transferring a geometric pattern from a photomask to a light-sensitive chemical photoresist. Also known as photolithography or UV lithography, optical lithography can produce a geometric pattern on a thin film or directly onto the substrate. Semiconductor Wafer Measurements: Flatness and Shape During optical lithography, variations in wafer flatness must be smaller than [...]

Ensuring the proper operation of your aircraft engine is essential to complying with manufacturers guidelines for the safety and longevity of the aircraft. Ensuring engines are not operating outside acceptible vibration limits and operating optimally isn't just smart, it is vital to your business. Excessive engine vibration can lead to cracked turbine, fan and compressor components potentially leading to catastrophic failure. The costs of catastrophic engine failure due to an unbalanced engine can measure in the millions of dollars. As airlines push to get more and more life out of their aging fleets, the need to properly maintain the [...]
