Target Depth Not Reached¶
Symptoms¶
- The written depth is too shallow even when the depth feedback sets the electrostatic force voltage to the maximum possible value.
- The top and right hand edges of the patterned areas are deeper than the rest of the written area.
Cause¶
The tip is too cold to evaporate the PPA correctly.
Solution¶
Increase the writer temperature/voltage to improve the patterning.
