The Glasgow group has had many years of experience working on CMOS sensors (including the HEPAPS and MI3 projects) which are detailed here CMOSOldGlasgow.
For many years these devices have been used for imaging sensors and even for tracking devices in particle physics. However, due to their collection via diffuison these devices have been limited in particle physics application where there are significant radiation levels. New devices with a depleted volume are now possible that allow collection via drift rather than diffusion. This should enhance the charge collection over devices that coolect via diffusion only. There are two technology classes High Resistivity (HR) substarte with a backside bias contact (HR-CMOS) and High Voltage CMOS device designs.
