  • FSM 413

    This FSM 413 Echoprobe(TM) sensor used patent pending Infrared (IR) Interferometric Technique which provides a direct and accurate map of thick to ultrathin wafer measurement of substrate thickness, and thickness varia tion (1TV).

    Several materials transparent to in IR beam, such as Is, GaAs, InP, SiC, Glass, Quartz and many polymers spot, (smaller spot sizes are available). Using a Single probe system, substrate thickness of conventional wafers with patterns, tapes, bumps or bonded wafers mounted on carriers can be determined with high precision and accuracy.

    When configured as a Dual probe system, the FSM413 also provides measurements of total thickness of the wafer including substrate thickness and the patterned height thickness. Options are available to measure the wafer warp, trench depth and cia holes, including high aspect ration trenches and vias in MEMs type applications. Various specialized MEMs applications including Membrane Metrology and Bump Height metrology are also available.
