Abstract:
1. A method of fabricating an X-ray detector, comprising the steps of: providing a substrate having a capacitor area and a transistor area; forming a common line over the capacitor area and an array of semiconductor-based switching elements over the transistor area; forming a first conductive layer over the capacitor area covering and contacting the common line; forming and patterning a conformal passivation layer to expose a portion of the semiconductor-based switching elements; forming and then patterning a planarization layer to expose a portion of semiconductor-based switching elements in the transistor area and a portion of the passivation layer in the capacitor area; and forming a conformal second conductive layer on the patterned planarization layer, wherein the second conductive layer, the first conductive layer and the passivation layer in the capacitor area constitute a storage capacitor structure.
