GAAS SUBSTRATE THICKNESS MEASUREMENT
Industry Semiconductor Applications Gaas Substrate Thickness Measurement Measurement Type Thickness Description Measuring Thickness of Wafers with Different Chemistries Introduction: Silicon wafers are ordinarily highly conductive and easy to measure with standard capacitive displacement sensors (See MTI’s Proforma 300i). Measuring the thickness of GaAs wafers that have high bulk resistivity (>10k Ohm/cm) is a little more difficult because the wafers act as non-conductive insulators in a capacitive sensor’s measuring field. Fortunately, MTI has a solution to this problem. Solution: It’s possible to measure the thickness and TTV of high resistivity semiconducting wafers (like GaAs) using non-contact capacitive [...]

Accumeasure Probes
High resolution, low cost sensors to measure gap and displacement in industries such as semiconductor, electronics, R&D applications and many more. For grounded targets MTI offers standard capacitance probes. For ungrounded or poorly grounded targets MTI offers push/pull dual sensor probes. Both types of probes are available in stainless steel construction or flat and flexible polyimide construction. Polyimide flat probes are perfect for gap applications or confined spaces. How Probe Sensors Work Standard capacitive sensors require the target to be electrically grounded (for position, gap and vibration measurement applications). Current flows from the probe face to the target and back [...]
