Emission Microscope PHEMOS Series

HOME / Products / HAMAMATSU / Emission Microscope PHEMOS Series




The PHEMOS-1000 is a high-resolution emission microscope that pinpoints failure locations in semiconductor devices by detecting the weak light emissions and heat emissions caused by semiconductor device defects. Since the PHEMOS-1000 is usable in combination with a general-purpose prober, you can do various analysis tasks by using the sample setups you are already familiar with. Installing an optional laser scan system allows acquiring high-resolution pattern images. Different types of detectors are available for various analysis techniques such as emission analysis, thermal analysis, and IR-OBIRCH analysis. The PHEMOS-1000 supports a wide variety of tasks and applications ranging from prober socket boards to a large-size 300 mm wafer prober.

Display functions
Superimposed display/contrast enhancement function

The PHEMOS-1000 superimposes the emission image on a high-resolution pattern image to localize defect points quickly. The contrast enhancement function makes an image clearer and more detailed.

Display function

  • Annotations: Comments, arrows, and other indicators can be displayed on an image at any location desired.
  • Scale display: The scale width can be displayed on the image using segments.
  • Grid display: Vertical and horizontal grid lines can be displayed on the image.
  • Thumbnail display: Images can be stored and recalled as thumbnails, and image information such as stage coordinates can be displayed.
  • Split screen display: Pattern images, emission images, superimposed images, and reference images can be displayed in a 4-window screen at once.
