From news release:
PET Foundation Process Design Kit ("PDK") targeting 40-nm - Sentaurus modeling (a Synopsys tool) has been performed with new fabrication innovations to achieve controlled scaled device operation. These modeling predictions are guiding and confirming the device prototype development and testing.
About Sentaurus.....
Benefits of Sentaurus:
- Explore new device concepts for which fabrication processes are not yet defined
- Characterize electrical, thermal and optical behavior of semiconductor devices for fast prototyping, development and optimization of their performance
- Shorten development time by supplementing experimental data with deep physical insight from simulation
- Study sensitivity of device characteristics to process variation for optimizing parametric yields
