As LED devices include complicated nanoscale thin film structures, TEM/EDS/EELS are critical techniques for quality control and failure analysis. Outermost Technology has established a set of services for LED device characterization and has been recently selected as a high-volume service provider by a world leading LED manufacturer.

PALS/DBS are non-destructive spectroscopic techniques to study voids and defects in single crystalline materials. These techniques can identify the type and distribution of defects along the film’s depth. It is an ideal metrology for the LED industry.

PCA is an orthogonal transformation to convert a set of observations of possibly correlated variables into principal components. The PCA-ToF SIMS can be widely used for materials identification or for mapping (polymers, organics, or bio-materials}.

OBIRCH is a very powerful fault localization technique for IC’s. In Failure Analysis OBIRCH is commonly used to localize metal shorts, active area short, shorts in source, and drain wells.
