High density capacitor integrated into focal plane array processing flow

Abstract

Methods and structures of photodetectors are described. The structure may include a readout integrated circuit substrate having an internally integrated capacitor. The structure may additionally include an external capacitor overlying the readout integrated circuit substrate. The external capacitor may be coupled with the internally integrated capacitor of the readout integrated circuit substrate, and configured to operate in parallel with the internally integrated capacitor of the readout integrated circuit substrate. The structure may also include a detector overlying the external capacitor.

Dependencies are inferred from the claim text.
