The Proforma 300i wafer thickness gage is a capacitance based, differential measurement system that performs non-contact thickness measurements of semiconducting and semi-insulating wafers. By utilizing MTI Push/Pull technology, the Proforma 300i does not require the wafers to have a consistent electrical ground resulting in exceptional accuracy and repeatability for most wafer types. The Proforma 300i system includes full remote control operating software and Ethernet network interface capability.

 

Features:
  • Front USB port enables easy data storage to flash drives
  • MTI Instruments’ Proprietary Capacitance Circuitry for Outstanding Accuracy and Dependability
  • Non-contact Measurements
  • Optional wafer measurement rings
  • Wafer stops for exact centering
  • Ethernet interface
  • Full remote control software (Windows compatible)
  • Optional calibration wafers

Product Details:

Vibration or Runout at Speeds500 kHz
ResolutionsUp to 0.05 mu in (1.25 nm)
Operating Temperature Range7 deg C to 40 deg C

Measure dynamic edge position, displacement. The unique fiber optic probe design can accommodate a wide range of target reflectivity or shape, making it ideal for wide variety of applications such as ultrasonic horn vibration or Piezo electric materials studies.

 

Features:
  • Random Fiber Distribution- As the probe-to-target distance increases, increasing amounts of light are proportionally captured by the receive fibers.
  • The result is a very sensitive, linear output response (Range
  • A continued increase in probe gap will proportionally reduce the amount of light received, results in a sensitive, linear output response (Range 2) with a large measurement range and standoff distance.
