Process Design Kit (PDK) TEST
CORNERSTONE offers eight cutting-edge technology platforms, each supported by open-source Process Design Kits (PDKs) for Silicon-on-Insulator, Silicon Nitride, Suspended-Silicon, and Germanium-on-Silicon. With wavelength coverage spanning from the visible spectrum (520 nm) to the mid-infrared (14 µm), these platforms enable an exceptional range of applications from high-speed datacom to quantum technologies, biosensing, and beyond.
Open source standard components
The CORNERSTONE platform has a number of open source standard components available for use for each of its platforms.
