Z-Factors

Empirical Determination of Z-Factor

Unfortunately, Z Factor and Shear Modulus are not readily available for many materials. In this case, the Z-Factor can also be determined empirically using the following method:

  • Deposit material until Crystal Life is near 50%, or near the end of life, whichever is sooner.
  • Place a new substrate adjacent to the used quartz sensor.
  • Set QCM Density to the calibrated value; Tooling to 100%
  • Zero thickness
  • Deposit approximately 1000 to 5000 A of material on the substrate.
  • Use a profilometer or interferometer to measure the actual substrate film thickness.
  • Adjust the Z Factor of the instrument until the correct thickness reading is shown.

Another alternative is to change crystals frequently and ignore the error. The graph below shows the % Error in Rate/Thickness from using the wrong Z Factor. For a crystal with 90% life, the error is negligible for even large errors in the programmed versus actual Z Factor.

Notes:
  • Bonding service not available on this material.
  • Due to the highly reactive nature of these materials, packaging in oil is required to reduce the opportunity for oxidation or other reaction. Please click here for the recommended cleaning procedure.
  • This material is a Hazardous shipping item. This product must drop ship from US headquarters on customer provided Fed Ex Account.

Hazard Notes:
  • Hazardous Materials: Hazardous shipping charges may apply.
