ABSTRACT:
An apparatus is directed to increasing the resolution of digital color imaging that includes a photosensing semiconductor structure. The apparatus provides a monocrystalline silicon substrate, a first buffer layer epitaxially formed and overlying the monocrystalline silicon substrate, and a first photodiode layer overlying the first buffer layer and operable to provide a first signal indicative of a color associated with a first wavelength of light. The apparatus may further provide a second buffer layer overlying the first photodiode layer and a second photodiode layer overlying the second buffer layer operable to provide a second signal indicative of a color associated with a second wavelength of light. The first buffer layer may include a first monocrystalline oxide layer epitaxially formed to the monocrystalline silicon substrate, a monocrystalline compound semiconductor material overlying the monocrystalline oxide layer, and a second monocrystalline oxide layer overlying the monocrystalline compound semiconductor material layer and epitaxially formed to the monocrystalline compound semiconductor material layer.
