The Multiposition Wafer Probe combined with the ResTest Test Unit provides a high quality, easy to use system for measuring the sheet resistance and/or volume resistivity of wafers up to 200mm (8″) in diameter.
Four-Point-Probes offers 4 point probe equipment for measuring the sheet resistance and bulk (volume) resistivity of materials used in the semiconductor industry, universities, and in materials science including thin films, wafers, ingots, and other materials and conductive coatings.
