High Resolution Low and High Magnification Optical Microscopy
In conjunction with the industry leading deprocessing abilities, the range of low and high magnification optical microscopy tools at Sage Analytical Laboratories are able to provide high resolution captures of failure mechanisms. In terms of magnification, our equipment exceeds the limits created by optical light and can resolve failure mechanisms ranging from high level package damage on the order of millimeters down through metal level anomalies on the order of micrometers. In addition, we employ different imaging techniques such as bright field, dark field, DIC/Nomarski, and light shift.
The lab is currently equipped with Leitz and Olympus Low and high magnification optical microscopy tools and capture systems which allow us to provide extremely high quality inspection and imaging of devices in short order. This equipment, although somewhat standard in a lab environment becomes extremely powerful for inspection and documentation when coupled with modern software packages.
In addition to the Low and high magnification optical microscopy tools, Sage is also equipped with a Keyence Low and High Optical Microscopy machine. This piece of equipment improves on the standard optical microscope by providing a software interface tailored specifically for the hardware. By setting an area of interest, the low and high magnification lenses produce large area, high depth of field images with precise stitching over the entire area of interest along with accurate layering for beautiful images in perfect focus in all planes.
The ultimate goal of any failure analysis flow is to provide a detailed image of the failure mechanism as well as the path required for the failure analysis engineer to arrive at a conclusion. Crisp images of the flow allow for detailed review and correlation with fault isolation techniques, giving a streamlined overview of how the final results were obtained. However, beyond final captures and results, the Low and high magnification optical microscopy tools help our staff with interim inspection and documentation along the analysis path.
