Device processing
Design & Technical studies
Vmicro works at all Technological Readiness Levels (TRLs): from ideas at TRL1 to preproduction runs at TRL7–9.
- Test your device concept with short design or technological loops to help decision-making.
- Establish design rules for increasing the TRL of your project.
- Start the first reliability studies.
Vmicro explores design variations for :
- Preparing larger scale transfers to foundries
- Device performance assessments
Process integration
- Vmicro provides complex process sequences tailored to go from substrate to final device.
- We provide design service to our customers at each step of their projects, from concept to design rules definition and mask layout.
- Vmicro’s main know-how is based on years of experience in micro and nanotechnology and covers silicon processing for MEMS, photonic and electron devices.
