Digital Ultrasonic Array Data Capture
Digital Ultrasonic Array Data Capture Customer Case A customer possesses a commercial medical diagnostic ultrasonic system. The ultrasonic sensing head consists of an ultrasonic generator transducer and an 8' x 8' two-dimensional array of receiver transducers. The sensing head is pressed against the tissue under study and the generation transducer is periodically excited so that it emits a burst of ultrasonic energy. After each burst, the receiver array registers ultrasonic echoes reflected off tissue structures from each transducer element. In normal operation, digitized array data from each element is numerically processed and combined to construct a display image of [...]

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 [...]

Why Demand for SiC Wafers is Hot and Durable
Why Demand for SiC Wafers is Hot and Durable Pardon the pun, but SiC wafers are a hot item for high-temperature applications. Silicone carbide (SiC), a semiconductor containing both silicon and carbide, withstands temperatures up to 2700°C. Carborundum, as this durable ceramic is also known, finds additional applications in bulletproof vests, extrusion dies, sandpaper, and high-performance disc brakes. In electronics, SiC materials are used with light-emitting diodes (LEDs) and detectors. In the semiconductor industry, a market where interest is red-hot, SiC wafers are used in electronic devices that operate at high temperatures, high voltages, or both. Examples include electric [...]
Wafer Stress Analysis Using the 300iSA
Wafer Stress Analysis Using MTI Instruments Proforma 300iSAWafer processing involves several stages that may translate into mechanical alterations. Sometimes these alterations can cause deformities that render the wafer either unusable or that put it marginally close to not being usable. To determine this, stress analysis can be used.The Proforma 300iSA wafer characterization tool provides a software capability in which a wafer can be analyzed prior to processing and then after processing. The tool then evaluates how the wafer changed and hence, provides the resulting stress analysis.The software expects the customer to provide the material elasticity constants and to define them [...]

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 [...]

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 [...]
