The latest free update to NPGS v9.2 is available. Click Upgrade History for a summary of the improvements to NPGS. A complete improvement history is available on the update web page.

July 26, 2021: NPGS v9.2 is Released

NPGS v9.2 supports QCAD Professional in addition to the previously supported programs: DesignCAD Express v21.2, DesignCAD Express v16.2, and DesignCAD LT 2000. Any or all of these programs may be installed simultaneously and may be used with NPGS without conflicts.  A QCAD Professional site-license is highly recommended.  For universities, the QCAD Professional site-license allows unlimited installations within the university.

Pg_Ruler.exe:

This program is included in the latest release of NPGS, but is also available for download by anyone.  Pg_Ruler has a measurement mode which is very useful when working with SEM images, since it can easily be calibrated to the scalebar in an image.  It also includes an SEM optimization mode which is useful for systematic optimization using the mouse-control features on some SEM models..

Keithley 6485 Picoammeter:

Software to communicate with a Keithley 6485 Picoammeter through a serial port is available with NPGS at no charge. Current users can send e-mail to get a copy of the new software at no charge. The current release of NPGS also includes a feature to allow the user to call the new software so that multiple readings from the picoammeter can be averaged and automatically entered into the NPGS software before a pattern is written.

E-Mail Addresses:

If you have not already done so, please send e-mail to info@jcnabity.com and introduce yourself and your research.  This will provide me with a updated list of e-mail addresses, that may be used for special announcements, etc.  User e-mail addresses will not be incorporated into the NPGS web site.

Sample Pictures:

If you have samples made with NPGS that you wish to have displayed on this page, please send a gif or jpeg file by e-mail, or a hardcopy that can be scanned. Also, please include a short description of the processing, as well as the application and/or research that the sample is used in.  Alternately, if you have a picture that shows an interesting problem that can be encountered during SEM lithography that would be appropriate for the Diagnostic Images section of the NPGS Sample Pictures page, please send it as well.
