IMEC`S INTEGRATED SILICON PHOTONICS PLATFORM
IMEC’S INTEGRATED SI-PHOTONICS PLATFORM (ISIPP50G)
Imec offers an integrated silicon photonics (iSiPP50G) platform targeting the telecom, datacom and medical diagnostics industries.
The iSiPP50G platform co-integrates a wide variety of passive and active components, enabling competitive photonic integrated
circuits for short reach optical interconnects. Regular multiproject wafer (MPW) runs are available at fixed tape-in dates, enabling cost
competitive access by sharing mask, process and engineering costs. Ease of access is enabled through an extensive process design kit
(PDK). In addition, technology customization options are available through dedicated wafer fabrication services, which include full-size
reticles, delivery of full wafers, and access to specialty modules enabling advanced functionality.
ISIPP50G
The platform enables cost-effective silicon photonic ICs for:
O High-performance optical transceivers (50Gb/s and beyond) for
datacom, telecom and access networks
O Optical sensing (gas, pressure, strain) and read-out ICs
O Biomolecule detection, drug development, point-of-care diagnostics
The iSiPP50G platform co-integrates a wide variety of passive and active
components to support a wide range of optical transceiver architectures
at data rates of 25Gb/s or 50Gb/s. The offered integrated components
include low-loss waveguides, efficient vertical grating or broadband edge
couplers, high-speed silicon electro-optic modulators, high-speed germanium-silicon electro-absorption modulators and high-speed germanium
waveguide photo-detectors. iSiPP50G offers state-of-the-art performance, design flexibility and superior CD and thickness control. It is a fixed
process technology (130nm) with a validated device library.
ISIPP50G DESIGN KIT
To enable users access, imec provides an extensive iSiPP50G process design
kit (PDK). This kit includes process documentation, library performance,
layout guidelines for custom, design and verification rules. The PDK is
available upon signature of imec’s Silicon Photonics Design Kit License
Agreement (DKLA).
ISIPP50G MPW ACCESS
iSiPP50G is a fixed process technology with a validated device library. To
lower the cost for access, MPW runs are available at fixed tape-in dates,
allowing to share mask, process and engineering costs. Users in the USA
can contact MOSIS for accessing the iSiPP50G technology for R&D and
prototyping. Outside the USA, users can contact Europractice-IC for access.
