Greatly Improves SEM and Optical Imaging of Cross-Sections

Optical Imaging of Cross-section - Parallel Lapping - Nanolab Technologies 

 

Used for die or packages to expose and inspect electronic devices layer by layer.  Typically used as a follow up to a defect localization by another technique, such as Photon Emission Microscopy (EMMI)/Laser Stimulation.

The grinding and polishing steps in a metallographic preparation method can be accomplished in many ways and combinations.  Most steps are performed on a table-top unit that can be used for both grinding and polishing.  There are also systems that are strictly for grinding.

The goal of any method is to prepare a final polished specimen free of deformation and suitable for analysis.  The initial abrasive size should be as small as possible, yet be able to create a flat surface and remove any sectioning deformation.

Each subsequent step should induce as little deformation as possible while removing any damage from the previous step.  Using adequate lubrication, most commonly water, throughout the process will aid in minimizing deformation.

Did You Know?

The use of specimen holders produces superior surface flatness and edge retention compared to manual preparation.  Automated systems enable better control of variables such as the pressure applied to the specimen, the speed and relative direction of the work surface, and the application of abrasive.  All of these impact the quality of the final results and overall length of preparation time.

Tips, Tricks & Techniques

To ensure specimens are loaded plane to one another, always use a loading plate.  This simple step can save significant grinding time.
