Discover our easy ECORCE TCAD tool in 5 minutes !
ECORCE (Etude du COmportement sous Radiation des Composants Electroniques) is an European specialized Technology Computer-Aided Design (TCAD) software developed by Delphea. It focuses on the simulation of radiation effects on semiconductor devices, making it essential for industries that operate in high-radiation environments such as space, nuclear, and aerospace electronics.
Key Features of ECORCE
1. Radiation Effects Simulation
ECORCE provides a comprehensive suite for simulating radiation-induced degradation in semiconductors:
- TID (Total Ionizing Dose): Assess long-term cumulative damage in devices.
- SEE (Single Event Effects): Evaluate the impact of single high-energy particles on device performance.
- TNID (Total Non-Ionizing Dose): Analyze displacement damage affecting device lifetime.
2. Automatic Dynamic Meshing
ECORCE uses an automatic dynamic mesh generator that adds and removes nodes at each step of the modeling in stationnary and transient mode. To date, it is the only TCAD tool that offers this functionality. It completely frees the user from the most complex task of creating a TCAD model: meshing, and guarantees:
- High precision in modeling complex device geometries.
- Faster computation without manual mesh adjustments.
- Accurate results even for highly non-linear effects in radiation environments.
3. User-Friendly Interface
Unlike traditional TCAD software, ECORCE provides a graphical user interface that simplifies:
- Defining device geometries
- Selecting physical models
- Visualizing simulation results
This reduces the learning curve and allows engineers and researchers to focus on analysis rather than software complexity.
4. Active development and Innovation
At Delphea, we are proud of the growing number of scientific publications that showcase the reliability and adoption of ECORCE in the research community. Our team regularly publishes peer-reviewed papers in journals and conference proceedings on topics such as radiation effects in semiconductor devices, advanced TCAD modeling, and radiation-induced failure mechanisms.
We actively present our work at high-profile conferences, including RADECS (Radiation and its Effects on Components and Systems), the IEEE Nuclear and Space Radiation Effects Conference (NSREC), and other international symposia focused on radiation-hard electronics and high-reliability systems.
By engaging directly with leading experts and contributing to collaborative research, we ensure that ECORCE stays at the forefront of radiation TCAD simulation. This active presence in the scientific community not only reinforces the credibility of ECORCE but also drives innovation and strengthens our reputation as leaders in modeling radiation effects on semiconductor devices.
Applications of ECORCE
ECORCE is widely used in high-reliability electronics design, particularly for:
- Space electronics: Satellites, launch vehicles, space probes
- Nuclear instrumentation: Reactor sensors and monitoring devices
- Aerospace systems: Avionics and flight-critical circuits
- Research & Academia: Studying radiation effects on emerging semiconductor technologies
By predicting device degradation before manufacturing, ECORCE reduces costs, prevents mission-critical failures, and ensures long-term reliability.
Advantages Over Other TCAD Tools
While general-purpose TCAD tools like Synopsys Sentaurus or Silvaco Atlas are widely used, ECORCE stands out due to:
- Specialization in radiation effects, rather than general semiconductor modeling
- Dynamic meshing for faster simulations
- User-friendly interface suitable for newcomers and experienced engineers alike
- Seamless integration with particle transport tools like Geant4
These factors make ECORCE particularly suitable for space-grade and radiation-hardened semiconductor design. As an independent and specialized company, we focus entirely on radiation effects and high-reliability electronics. This dedicated expertise allows us to deliver highly targeted solutions that general-purpose TCAD tools often cannot provide.
