Can Flexfet be used to build imagers and other detectors?
A. Yes. Diodes built in the substrate typically require a large bias applied to the substrate. Detectors allow charge collection from high-energy particles passing through the substrate. The Flexfet process allows large substrate biases without performance degradation. Additionally, Flexfet is unaffected by the associated radiation-induced trapped charge in the BOX. Flexfet enables Monolithic Active Pixel Sensors (MAPS) by allowing logic and devices on the same die as the detector, reducing system cost and improving performance.
