Supply of approximately 800 high-quality, radiation-tolerant 3D silicon pixel sensors for the Phase-2 upgrade of the CMS Inner Tracker.

Item Description:

CERN intends to place a contract for the supply of approximately 800 single-sided 3D silicon pixel sensors fabricated on high resistivity p-type substrate, for the Phase-2 upgrade of the CMS Inner Tracker. The supply shall be delivered in the period between October 2021 and August 2023. Main features include: -Active thickness: 150 microns (um); -Maximum physical thickness: 270um; -Pixel cell size: either 50um x 50um or 25um x 100um; -Bump-bonding pattern: 50um x 50um; -Sensors array: 864 x 336 pixel cells; -Sensor size: ~44.35mm x 17.70mm. Sensors shall remain highly efficient and dissipate low power after irradiation to fluences of approximately 2e16 Neq/cm2. Breakdown voltage before irradiation shall exceed the full depletion voltage by at least 20V.

Interested firms shall have proven competence and experience in 3D silicon pixel fabrication.
