TCAD

Transistor-Level Performance Evaluation Based on Wafer-Level Process Modeling

By: Michael Hargrove, SP&I Engineer

Three years ago, I wrote a blog entitled “Linking Virtual Wafer Fabrication Modeling with Device-level TCAD Simulation” in which I described the seamless connection between the SEMulator3D® virtual wafer fabrication software platform and external 3rd party TCAD software. I’m now happy to report that device-level I-V performance analysis is now a built-in module within the SEMulator3D software platform.  Users are no longer required to export a mesh and import it into a TCAD platform, when performing transistor I-V simulation.  Now, once the 3D device structure is built in SEMulator3D, transistor I-V simulation can be performed directly within SEMulator3D without need for 3rd party solvers.  Contacts and bias can be applied using the SEMulator3D device design, and I-V transistor characteristics can be determined for specific steps in the process flow.  You can perform direct transistor-level performance evaluation inside the SEMulator3D software platform, without needing to export or import meshes. read more…

Nowadays, novel semiconductor technologies have brought complex process flows to the fab.   These process flows are needed to support the manufacturing of advanced 3D semiconductor structures. It can be helpful to model process flows, and their effect on a novel device, prior to physical fabrication.

Process Simulation vs. Process Emulation: is SEMulator3D really TCAD?

I was interested to note that Silvaco has recently listed SEMulator3D as a competitor for their VICTORY Process Cell software on their website. It’s great to be mentioned as a contender in the TCAD process simulation space. But I’d like to take the opportunity to examine the following question – are SEMulator3D and VICTORY Process Cell really direct competitors?

On the surface, both SEMulator3D and VICTORY Process Cell can do some similar things. Both tools are fast, layout driven process modeling engines that are designed to build 3D models of MEMS and semiconductor devices. Both tools can model individual process steps or entire process sequences, and can model a variety of process and device types. And both tools can create meshes suitable for further physics simulation.
