Victory Process
Victory Process 2D & 3D Layout-Driven Simulator
TCAD Process simulation is crucial to develop new technologies, as well as maintain existing semiconductor processes. Virtualizing the manufacturing process allows organizations to maintain a “digital twin” of their semiconductor process. Changes in process can be well understood; maximizing device performance, increase manufacturing yield, while minimizing number of engineering cycles and cycle time.

We are developing gallium oxide devices with a completely new proprietary manufacturing method. Utilizing a device simulator will become important in order to efficiently develop such new devices. For the decision to use Silvaco’s device simulator, the deciding factors were Silvaco’s extensive track record with wide band gap semiconductors, and Silvaco’s depth of knowledge of power devices. We expect to see even more progress in our development of GaO™ power devices as we move toward practical applications.

Silvaco provides state-of-the-art device models and TCAD tools that are widely used by semiconductor companies. We are excited to establish this joint development program with Silvaco so customers will have early access to our ReRAM technology on the most powerful simulation tools in the industry and can fast-track the release of their next-generation products. This is another key step by Weebit Nano to accelerate the incorporation of ReRAM technology by a larger number of OEM customers.
