Business Wire: TowerJazz announced it has signed contracts for two phases of development with the US Army RDECOM CERDEC Night Vision Electronics and Sensors Directorate (NVESD) for CMOS low light image sensor development for Army portable systems. As part of this effort, TowerJazz is expanding its aerospace and defense on-shore capability by introducing CIS foundry processes and solutions in its Newport Beach, CA facility. This project will result in advanced CIS technology at TowerJazz’s on-shore facility and provide the US Army with a solution for its demanding technology needs and provide state-of-the-art CIS technology for DoD CIS programs.
A key goal of the US Army RDECOM CERDEC NVESD program is to enable CMOS imagers with low noise and high sensitivity over a broad spectral range. TowerJazz was chosen as a development partner due to its pixel process which uses advanced methods and technology providing higher pixel performance than competing commercial approaches. The transferred 180nm CMOS image sensor process at TowerJazz’s US location is meant to be a viable, commercially sustainable foundry offering to support not only the Army NVESD and their suppliers, but all DoD agencies and other interested third parties.
The TowerJazz process will enable the design of the NVESD 4 Mpixel low light level BSI sensor and other low dark current, high performance imagers. TowerJazz will also evaluate the types of process flows needed to support fabrication of backside illuminated or SOI based CMOS image sensors.
180nm CMOS image sensor process and BSI ? Now why anyone want do that? Just go with simple proven FSI and get larger pixel size for low light sensitivity
ReplyDeletewhat is the sensitivity level required for this night vision applications?
ReplyDeleteTaking into the QE and the spectral response, a 10um x 10um pixel with 100% fillfactor will generate 3-5 electrons per frame at 25Hz. Is this enough for night vision applications?
"TowerJazz will also evaluate the types of process flows needed to support fabrication of backside illuminated or SOI based CMOS image sensors."
ReplyDeleteThe answer is in this phrase, this is a good way to evaluate the process flow for BSI at Tower.
