It is commonly used in failure analysis and non-destructive evaluation. The semiconductor industry has found the SAM useful in detecting voids, cracks, and delaminations within microelectronic packages. Most of them were described in detail in the monograph Advanced in Acoustic Microscopy, Ed. Sound hitting the object is either scattered, absorbed, reflected (scattered at 180) or transmitted (scattered at 0). It is possible to detect the scattered pulses travelling in a particular direction. A detected pulse informs of the presence of a boundary or object. The time of flight of the pulse is defined as the time taken for it to be emitted by an acoustic source, scattered by an object and received by the detector, which is usually coincident with the source. The time of flight can be used to determine the distance of the inhomogeneity from the source given knowledge of the speed through the medium. The transducer (or object) is moved slightly and then insonified again. This process is repeated in a systematic pattern until the entire region of interest has been investigated. Often the values for each point are assembled into an image of the object. The contrast seen in the image is based either on the objects geometry or material composition. The resolution of the image is limited either by the physical scanning resolution or the width of the sound beam (which in turn is determined by the frequency of the sound). Detecting discontinuities in silicon is just one of the ways scanning acoustic microscopy is being used for testing in the semiconductor market.
