Description

We propose an R&D program focused on the SK hynix 90 nm CMOS Image Sensor (CIS) process as a dedicated technology option for Future lepton collider vertex-detector MAPS. The near-term goal is to establish and characterize a first generation of reticle-scale pixel-sensor prototypes in this process, including sensor test structures, small matrices, readout architectures, and radiation-tolerance studies. The longer-term goal is to keep the sensor architecture, floorplan, peripheral readout, power distribution, and data-output scheme compatible with future stitched large-area sensors, so that the technology can evolve from proof-of-principle chips to realistic vertex detector in future collider.
