  • Non-destructive semiconductor wafer test system
    Patent number: 6125689
    Abstract: The invention provides methods and systems for identifying compounds released from a semi-conductor wafer. Compounds are released from the wafer by subjecting the wafer to a rapid temperature excursion in a very low pressure chamber. The released compounds are often isolated using gas chromatography. Diffusion between the layers of a multiple layer semi-conductor structure can be minimized by directly heating a target surface of the wafer using radiant heating.
