MTI Instruments Whitepaper: Capacitance Guide for Industrial Applications
Capacitance Guide for Industrial Applications This guide from MTI Instruments explains what you need to know about using electrical capacitance for measurement in industrial applications, including advanced manufacturing. Basic Principles Capacitance is the ratio of the change in an electric charge to the corresponding change in its electrical potential (i.e., voltage). Capacitors, components that that have the “capacity” to store an electric charge, consist of conductive parallel plates that don’t touch or connect with each other. Instead, these metal plates are electrically-separated by air or a layer of insulating material (i.e., the dielectric). MTI’s [...]
Whitepaper: Why Capacitance? Benefits and Applications of Digital Capacitive Sensors
Industry applications illustrate the versatility and benefits of today's digital capacitive sensor technology. The electrical capacitance formed between a capacitance probe and target surface varies as a function of the distance, or gap, between those two surfaces.
Ultrasonic Tissue Characterization
Ultrasonic Tissue Characterization Customer Case This customer's application is Ultrasonic Tissue Characterization. Their ultrasonic sensors transmit 16 signals. The customer's requirement is to capture 512 points on the 16 channels, average them together, and then store the data in a buffer, with the system running continuously. They would like to be able to update the average buffer and recapture data as fast as possible. They would then like to log the data to disk or process the data and display an image on the screen. Since the signals coming in from their ultrasonic sensors are very weak, the customer [...]
Whitepaper: Semiconductor Wafer Measurement for Increased Productivity
Semiconductor Wafer Measurement for Increased Productivity This three-part article describes how manufacturers leverage capacitance-based inspection systems for semiconductor wafers. The article reviews best-practices, consequences of failing to inspect semiconductor wafers and benefits of using semi-automated, fully-automated and manual systems for wafer metrology and inspection. Part 1: Why Disc Geometry Matters in Wafer Production Semiconductor wafers are cut from cylindrical silicon crystals, or ingots. The flatness of these disc-shaped wafers is controlled to tight tolerances to ensure that the entire wafer surface is suitable for integrated circuit (IC) production. If disc geometry is out-of-spec [...]
The Cost of Failing to Inspect Semiconductor Wafers
This is the second of three articles in Semiconductor Wafer Measurement for Increased Profitability. The first article in this series explains why disc geometry matters. The third article describes the benefits of using semi-automated, fully-automated, and manual systems for wafer metrology and inspection. Most semiconductor wafers are made of silicon, the second most common element in the Earth’s crust. Yet, silicon’s abundance does not mean that wafers are inexpensive. The pure form of silicon that’s used in semiconductors does not occur naturally and must be refined and mixed with a dopant that alters material properties and electrical characteristics. Silicon ingots are formed, wafers [...]

led substrate sapphire thickness
N/A led substrate sapphire thickness Displacement Remember that old acronym, GIGO? Garbage in garbage out, it can apply to raw materials as well as programming. Sapphire wafers need to be of a certain quality to ensure maximum yield. EXCESSIVE TTV, BOW, AND WARP LEAD TO PREMATURE LED FAILURE LED MANUFACTURERS NEED TO INSPECT INCOMING WAFERS. WAFER PRODUCERS ALSO NEED TO CHECK AND CONTROL TTV, BOW AND WARP. The market for sapphire wafers, driven by the growth in LED manufacturing, is booming. While the price has come down significantly since 2011, the size of the wafers [...]
