Abstract:

The progress in the program for acoustic microscopy is described for the preceding six month interval. The acoustic microscope working at 2.5 GHz has been used to study a variety of materials and a number of integrated circuits. We are beginning to see interesting features in these micrographs - features which are not evident in the optical images. Some of the effort has been spent on improving the instrument so as to extract particular and specified information of a given object. This is being done in part with the aid of a dedicated microprocessor. Originator-supplied key words include Imaging Nondestructive evaluation Silicon and Image enhancement.
