Abstract
The images of a high‐frequency bipolar transistor obtained with an acoustic microscope are compared with those of a differential interference optical microscope and a scanning electron microscope in order to illustrate that the acoustic microscope can be used in a reflection‐type mode to obtain quality pictures of a surface containing integrated circuits. The frequency of the acoustic beam is 600 MHz and the resolution is near 2 μ.Keywords
