Silicon Photonics

With our many years of experience in the production of CMOS circuits for industrial, research and aerospace applications, we are the ideal partner for the further development of new manufacturing processes and the production of microchips and the processing of wafers. Add-on processes, hybrid flexible foil systems with ultra-thin chips and CMOS-compatible GaN-on-Si processes are further focus of our work.

Silicon photonics

With our new pilot line for silicon photonics, we can manufacture passive and active optical circuits and components, such as on-chip interferometers, ring resonators, active grating couplers, etc. Optical chips are manufactured on 150 mm SOI substrates using CMOS and MEMS technologies. All silicon photonics chips or substrates can be manufactured in-house including the packaging and interconnection technology.

Hybrid systems-in-foil
Flexible electronic systems with integrated silicon chips are the basis for new products in the fields of medical technology, automation and mobility. Our technologies provide solutions for mechanically bendable and reliable electronics.




Integration of thin chips
For chip integration, we have techniques to thin wafers and individual dies for thicknesses as thin as 20 µm. We have proven methods to handle and assemble the flexible chips. For chip integration in foil systems, we use the patented Chip-Film Patch (CFP) technology, which allows the contacting of the smallest pad geometries (< 5µm).

Research and Development
We develop hybrid systems in foil (HySiF) together with partners for various applications. A chip-film patch with evaluation ASIC provides digitization of sensor data for respiratory monitoring of premature infants. Embedded image sensors and communication chips as well as antennas integrated into the foil enable wireless data transmission in the GHz range.

GaN technology
- We process GaN-on-Si wafers in a CMOS-compatible environment. Our range of performance:
- GaN-on-Si technology line for 150 and 200 mm wafers
- Wafers (CMOS-compatible)
- Inline measurement equipment (DC measurements, pulsed and capacitance-voltage measurements on fully or partially processed wafers up to 200 mm diameter)
- Fully automated standard measurements for efficient mapping of essential device parameters for entire wafers
- Customized evaluation software to organize and sort large data sets
