CLL Forces¶
The CLL forces panel (Figure 82, 84, 85) provides functionality to set the write force voltages for patterning.
Open the CLL forces panel
Write Forces Tab¶
Session Mode: Read-Only or Write-Read
The session mode can be changed only in the floorplan panel.
Write Force Voltages:
Init Automatically: Derive write forces from the previous session
Init with Linear Ramp: Set a linear write force ramp (Figure 83)
Enable Depth Feedback: Optimize the write force voltages during patterning
Get Depth Feedback Data: Send detailed information about the depth feedback process from the real-time controller
Read Corrections: Correct read artifacts during reading
Thermal Conductance: Correct thermal conductance image
Reader Drift: Correct reader drift
Depth Feedback Data Tab¶
Iteration Data
Iteration #: Depth feedback iteration number
Action: Depth feedback action performed
Read Line: Corresponding read line
Write Line: Corresponding write line
# Samples: Number of samples
# Seen Levels: Number of seen levels
Z Drift Correction Tab¶
The Z drift correction tab (Figure 86) provides functionality to correct drift in forward height during a CLL Runtime operation. The height difference between the forward height and the surface in the read margins is measured and held constant. This improves the stability of the writing parameters.
Enable Z Drift Correction: Drift correction should be enabled during normal operation. The correction may fail if the read margins are not flat, e.g. when stitching fields.
