Dr. Simard-Normandin has held the positions of Manager - Materials and Device Analysis at STMicroelectronic's Centre for Microanalysis and Manager of Materials and Structures Analysis at Nortel Networks. In 2002 she founded MuAnalysis Inc., a privately-owned Canadian company offering expertise in failure analysis, materials analysis and reliability testing.
Laser Scanning Microscopy (LSM) is a digital microscopy technique. The main application of LSM in counterfeit detection uses its ability to see through silicon and other optically opaque semiconductor materials allowing inspection of markings, layout etc. from the back of the semiconductor . To take advantage of this feature a laser of suitable wavelength must be used, usually a laser in the near-infra red spectrum. This is particularly useful in the inspection of flip chip devices.
In confocal mode (CLSM) it allows the collection of images at a series of focal planes, making the 3D reconstruction of the surface possible. Therefore CLSM is a non-contacting profilometry technique. CSLM can be used to compare surface roughness of devices, depth of laser markings, curvature and warping in the micrometer range. This can be particularly useful when known authentic parts are available for comparison purposes.
LSM and CLSM are optical techniques, therefore the achieved spatial resolution depends on the wavelength of the laser used and is generally in the 1 micrometer range. Analysis is done in air, there is no need for vacuum, thus allowing easier analysis of large samples. Since lasers come in different wavelengths, one can customize applications, for example: IR lasers see though most semiconductors. This presentation will explain the technique and present several examples of successful use in the detection of counterfeit electronic devices.
