The Sonix Echo VS is a scanning acoustic microscope used for metrology and inspection. It is a Sonix-branded acoustic inspection system and the model name given is Echo VS.[1]
A scanning acoustic microscope uses high-frequency sound waves to interrogate a part through a coupling medium, then scans the beam or the part to build an image from reflected acoustic signals. In semiconductor use, this class of tool is used to reveal hidden interfaces, internal voids, delamination, and other subsurface conditions that are not visible with optical inspection.
This class of equipment sits in the metrology and inspection portion of a semiconductor workflow. It is used after fabrication steps that can create buried defects or adhesion problems, and before downstream processing, assembly, or reliability screening where internal integrity matters.
Scanning acoustic microscopes are used for non-destructive inspection of wafers and packaged devices where subsurface defects must be detected without sectioning the part. Typical uses include checking for delamination, cracks, voids, and other hidden structural anomalies.
