Excellent! Now I see what you are saying. Which microscope are you using? Multimode, Dimension, Catalyst? Are you using CLZ? If so, I'm thinking that the feedback is not keeping up with the Z motion. I would suggest switching to open loop, but collecting the Z sensor as a separate channel so that...

You can use a "relative trigger" on the deflection signal to control the maximum tip-sample force in a ramp mode force-distance curve. For instance, if you set a relative trigger of 1nN, you will find that the force curve extends until the force reached 1nN and then retracts from that point...

Hi Sandeep, I recall there was a problem doing ramping (for instance I-V curves) in Point&Shoot mode or Array mode in v720, which was fixed in v730. Can you elaborate what kind of problems you have with v730 on lithography? It is easier for us to fix a problem in the latest version; than go back...

Dear Ki-Rak, Can you send me the manual for the Lock-in Amplifier you are using, I'd like to know what exactly are ADC1, ADC2, A, OSC Out. Here is my guess: ADC1 is to read in the modulated data, in this case, tunneling current. OSC Out is the AC drive signal, in this case, the dV. "A"...

Why Ramp mode should be used for Deflection S ensitivity calibration, not the “Update Sens” button in PeakForce QNM mode? Otherwise, why this button is shown?
