I recently submitted two abstracts to SISPAD 2009. Hope to find out in April if they will be accepted. I’m not sure what the pre-publication restrictions for SISPAD are, so I am not giving details at this time.

I’ve started a new website at http://www.tcadcentral.com. It is a wiki dedicated to technology computer aided-design. Please check it out, and let me know if you have suggestions, or would like to participate.

Linked in is a great tool to reconnect with former colleagues. I recommend you all check it out. It is interesting who you might run into in their groups. For example, check out the TCAD and Device modeling and simulation groups.

2008 was a fun year. I made a lot of progress with the simulator, adding 2d and 3d device simulation.

Hoping to share more with all of you soon.

Thanks to Addaption Technologies for putting together the new website. I’ll try my best to match up the theme here in the blog.

Here is Devsim’s first 3d simulation of a MOS transistor.  The coloring is the potential at zero bias.

Here is a 2d mosfet meshed with Gmsh and loaded into Devsim. Note that this is the same structure and doping which was originally shown here in my first post.

It just looks a lot better having used a nicer meshing tool than the one built into the software.

As before, the red areas are the electron concentration.

3d diode

Turns out Gmsh was an excellent choice for a mesher.  It is a very usable tool for creating structures.  Almost reminds me of mdraw.

The result is a 3d (quasi-1d) diode structure.  The spot in the middle is the magnitude of the electric field.  Visualization is done in Paraview.

Mulling over the importance of 3d simulation.  I’m by no means a meshing expert.  Looking for third party tools to create tetrahedral meshes.  As of now gmsh seems to look promising.

What are the most important features in a semiconductor device simulation software?

Is it accuracy, number of models, advanced models, 3d? What about ease of use, scripting capability, extensibility? Anything to be said for licensing models or price?
