Abstract: Measuring apparatus and method for monitoring fabrication of a semiconductor wafer by exciting and measuring vibrations of the wafer substrate. A measurable parameter of vibration (e.g. frequency) is indicative of mass of a vibrating region. Mass change caused by wafer treatment is reflected in changes in vibration measurements taken before and after that treatment. The apparatus includes a wafer support e.g. projecting ledge (19), a vibration exciting device e.g. contact probe (28) or pressure differential applicator, and a measurement device e.g. frequency sensor (62).

Abstract: A measurement device and method for diagnosing noise in fluidic systems. A microphone, which is arranged at least partially in the area of the flow medium, compensates for pressure surges in the flow medium. The microphone receives the noise via a membrane and converts it to an electrical signal for evaluation of the noise source by an electronic diagnosis unit. To compensate for pressure surges in the flow medium, the membrane of the microphone is arranged in a housing, which is open on both sides of the membrane and whose two openings have pressure applied to them by the flow medium as a sound source, with at least one of the two openings being provided, in order to detect noise, with filter means for attenuation and/or time delay of frequencies which are in an expected noise spectrum, while the filter means allows lower frequencies produced by the pressure fluctuations in the flow medium to pass through.

Abstract: A method and apparatus for effecting ultrasonic flaw detection of an object processes an echo signal received from the object being tested in at least three signal channels, wherein the echo signal is scaled to different degrees along each channel to increase and extend the dynamic range of an associated A/D converter system, in a manner which dispenses with the need for using numerous analog high pass and low pass filters and a variable gain amplifier. This reduces complexity and avoids performance limitations. The digital to analog converters sample the differently scaled input signal and a selection circuit selects the output of the digital output obtained from that analog to digital converter which has the highest gain, but which has not overflowed. The digital outputs are seamlessly merged to produce an output that can be displayed as a scan display which shows the location of faults.
