Dimension TM 3100 Manual Version 4.43B phần 9 potx

Electric Techniques 16-24 Dimension 3100 Manual Rev. B Phase Detection continued Note: For software versions 4.23 and lower set Interleave scan to Lift and switch Interleave mode to Enable in the Interleave Controls panel. 8. Set the Channel 2 Scan line to Interleave to display interleave data. Note: For software versions 4.23 and lower, there are no separate Analog 2 setting in the Interleave Controls panel. Set Analog 2 in the Feedback Controls panel to 0 volts. 9. In the Interleave Controls panel set Analog 2 to the desired voltage. Note: Applying a voltage during the main line can make Tapping Mode operation difficult. 10. Optimize the Lift scan height. For high-resolution, set the Lift scan height as small as possible without crashing the tip into the surface. There are two ways to determine if the tip is touching the surface: • If the tip crashes into the surface, it typically creates bright or dark specks or streaks in the image. Also, if the Lift scan height is set extremely low, the tip may continuously “tap” on the surface during the LiftMode scan. • Toggle between the Interleave and Main scan lines for the phase image. If the two images appear similar this indicates the tip is continuously tapping on the surface during the LiftMode scan. Increase the Lift scan height until the Interleave scan image changes indicating that the tip is oscillating above the surface and not continuously tapping. 11. Adjust the sample or tip voltage to confirm that contrast is due to electrical force gradients. Electric Techniques 16-24 Dimension 3100 Manual Rev.
