The Tencor-KLA P17 stylus profiler comes with advanced data analysis software called APEX. We have an extra license for the software installed on a computer called NTCH-D0186 at Nanolab. The computer is currently located in the basement of building 346 in room 904. You will find it at the back of the room between the ALD and the PowderXRD.

You can access your data on the M drive, O drive, OneDrive or however you usually access data on our network.
 
==Remote access to the analysis computer ==
Remote access to the Apex program is a little bit complicated. This is because the Apex program doesn't recognize the license dongle if you simply use Remote Desktop.
 
Here's how to open Apex remotely on the analysis computer:
*Connect to DTU's network by VPN. This is necessary even if you are physically located at DTU unless you have a LAN cable connecting you to the DTU network. Use the service Cisco AnyConnect Secure Mobility Client and connect to AIT Extra-VPN with your usual credentials.
 
*Connect to the computer NTCH-D0186 with the Remote Desktop Connection app on Windows (in Danish "Fjernskrivebord"). Again log on with your DTU credentials. If someone else is logged in, try again a bit later. Please note that you will only be able to log on using Windows Remote Desktop if you are have been trained to use the P17 profiler and are authorized in LabManager. Contact the Thinfilm group if you're having problems with accessing the computer.
 
*On the NTCH-D0186 computer, open TeamViewer, which is pinned to the task bar.
 
*Close the Remote Desktop Connection and open TeamViewer on your own computer. You can download Teamviewer from www.teamviewer.com. We have a number of pro licenses, which you can obtain by writing to our IT administrator, Thøger Eskildsen (thes@dtu.dk). If you are a student or just want to try it out, you can use the free version.
 
*Use TeamViewer on your own computer to log on to the analysis computer. You will find the login information in a small txt file in LabManager on the Equipment page for the P17 under the Documents tab / Technical information. You will subsequently need to logon to the computer with your DTU credentials as though you were physically present in front of it. Now you can open and use the APEX software with the shortcut on the Desktop.
 
*IMPORTANT: Remember to close the connection after use.

Apex software for data analysis

The Tencor-KLA P17 stylus profiler comes with advanced data analysis software called APEX. We have an extra license for the software on a computer in the basement of building 346 which you can use either through remote access or directly at the computer. The computer is physically located at the back of room 904 between the XRD Powder and the AFM. For remote access please see under technical documents in LabManager (requires login).

Notice that the data has to be in a format that Apex can open. For line profiles that means you have to find the data in the Profiler Software first (on the P17 computer in the cleanroom). With the data open or selected, press the Apex button and save it in Apex in a native format. It is also possible to check a box in the profiler scan recipe that makes it possible to open the data in Apex automatically (see the Profiler Help document for more details or ask staff). Finally some data formats (e.g., 3D maps and 3D stress data) can always be opened in Apex.

How to use the software

How to choose to show only the measured line scans rather than the interpolated surface that APEX likes to calculate (see orange arrow).

There are a number of tutorials on how to use APEX and a thorough help document which you will find when you open the program. There is also a small introduction as an appendix to the P17 help document.

Apex offers many formats for saving the data in nice reports and various options for exporting data.

If APEX has automatically generated a surface from your line profiles of data, it is possible to view the underlying profiles by right-clicking on the surface and choosing Points Drawing instead of Lines Drawing or finding the same option (Points drawing) in the top ribbon. See figure on the right.

If you learn something cool about Apex that you'd like to share, please let us know.

Best of luck and please contact characterization@nanolab.dtu.dk if you have any questions or helpful tips.
