The Benefits of Manual, Semi-Automated, and Fully-Automated Systems for Semiconductor Wafer Inspection and Metrology
This is the third of three articles in Semiconductor Wafer Measurement for Increased Profitability. The first article in this series explains why disc geometry matters. The second article examines the cost of failing to inspect semiconductor wafers. Fully automated systems that can load, scan, and unload wafers are fast, convenient, and efficient at high volumes. They’re useful for checking every wafer in every batch, but these systems are expensive. Semi-automated and manual systems cost significantly less and are generally used for lower volumes; however, they’re also easy-to-use and can make fast, accurate measurements that support production flow. Semi-automated and [...]
TESTING CHARGE AMPLIFIER GAIN AND FREQUENCY RESPONSE WITH A SIGNAL GENERATOR
[Application Note 40518] Piezoelectric transducers produce small electrical charges in response to pressure. Their sensitivity, ruggedness, and stability at high temperatures make them an essential building block of many accelerometers and pressure sensors. Applications include turbine vibration measurement (accelerometers) and combustion dynamics monitoring (pressure sensors). Typically, the high-impedance charge output produced by a piezoelectric transducer must be conditioned and amplified before transmission across system cabling to the data acquisition and measurement instrumentation. This conversion is accomplished with a device called a charge amplifier. Problem Over time, a charge amplifier’s signal response can drift. Damage to the charge amplifier or associated [...]

Why Disc Geometry Matters In Wafer Production
This is the first of three articles in Semiconductor Wafer Measurement for Increased Profitability. The second article examines the cost of failing to inspect semiconductor wafers. The third article describes the benefits of using semi-automated, fully-automated, and manual systems for wafer metrology and inspection. 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 after cutting, it may be possible to reprocess the wafer. Cutting is only the first [...]
THICKNESS INFORMATION OF COMPOSITE MATERIALS
Composite materials consist of two or more materials which include a substrate or base material such as paper, cotton cloth, or glass cloth along with a resin or adhesive such as epoxy, melamine, or silicone. To make a thermoset laminate, the base material is coated with the adhesive so that layers of material can be pressed under heat and pressure into sheet form. The Problem: Composite material thickness needed to be verified prior to forming or machining. Due to the size of the sheets typical measurement techniques were not suitable. A consistent method to accurately measure the board thickness [...]
TIRE TREAD INSPECTION WITH 1D LASER SENSOR
Tire manufacturers wants to satisfy their customers, and protect themselves from liabilities, manufacturers are moving to 100% tire inspection for defects and abnormalities. Defects not only cause potential safety issues but they can also introduce unwanted vibration into the vehicle suspension system. Belts can be overlapped, or not cover the complete tire surface, causing weak or bubbled areas and imbalances. The tread depth can be too shallow, leading to decreased service life. An uneven tire can cause excessive runout and vibration. MTI was approached by a major manufacturer requesting a solution to measure tread depth, runout and blistering. They [...]
Torque Converter
Industry Automotive Applications Torque Converter Measurement Type Surface Description Since minute defects in the torque converter casing wall thickness can result in unacceptable and dangerous torque converter expansion, a precision measurement system was needed to measure the impeller hub displacement and thus the torque converter axial displacement. An AC dynamometer would be required to spin the torque converter at a high rate of speed while a fast response hydraulic system is needed to pressurize the converter to pressures up to 150 psi. MTI’s MicroTrak laser sensor was selected because it offered [...]
FIBER OPTIC PROBES MEASURE STATOR BAR VIBRATION
[Application Note 11718] One of the primary concerns in large generator design is vibration. Excessive vibration can lead to premature breakdown of insulation and other materials, ultimately resulting in early failure of the generator itself. The Problem A leading manufacturer of power generating equipment required a sensing system able to measure stator bar vibration in a partial generator mockup. Specifically, the company’s multi-day testing program demanded a sensing system that was immune to the large magnetic field generated by live stator bars capable of withstanding high heat built up from prolonged testing, and compatible with a proprietary stator bar [...]
How Capacitive Measurement Can Help Reduce Packaging Waste
Product packaging is often made of lightweight polymeric foams or plastic sheets and films. These materials are relatively inexpensive, but manufacturers still want to minimize waste and maximize yields. Across high volumes of low-cost materials, even a small per-unit savings can become significant, especially as the price of petroleum – a key ingredient in many polymers – continues to rise. For companies with environmental sustainability efforts, there are other important considerations as well. The excessive use of packaging materials can contribute to environmental pollution, especially with polymers that are slow to degrade. Yet, materials such as plastic sheets and [...]
