New backside silicon image enhancing software
New backside silicon image enhancing software
Keywords Hypervision, Software
New software that greatly improves critical reference images in backside emission imaging is now available from Hypervision, the maker of emission microscope systems (Plates 4a and 4b).
Emission images locate chip-level static and functional defects. The first step in backside imaging is thinning of the silicon to as little as 80 microns. The complete emission image consists of an overlay of:
- 1.
the light emitted by defects; and
- 2.
the illuminated reference image showing circuitry.
The new software eliminates glare from the polished silicon and yields a complete overlay image in which contrast and resolution are similar to those in conventional frontside emission images. Backside imaging is a necessity for advanced DRAMS, LQCs, flip chips and other designs where the front side is inaccessible.

The new image enhancing software is designed for use with Hypervision's BEAMS™ and BEAMS Jr™ emission microscope systems. Significant image enhancement for contrast and sharpness is achieved.
