Abstract:
1. A process for fabricating a tandem color photosensing semiconductor structure comprising: providing a monocrystalline silicon substrate; depositing a first buffer layer overlaying the monocrystalline silicon substrate, the first buffer layer epitaxially forming a monocrystalline oxide layer overlying the monocrystalline silicone substrate; forming a first photodiode layer overlying the first buffer layer, the first photodiode layer operable to provide a first signal indicative of a color associated with the first wavelength of light forming a second buffer layer overlying the first photodiode layer; and forming a second photodiode layer, the second photodiode layer operable to provide a second signal indicative of a color associated with the second wavelength of light, forming a first monocrystalline oxide film overlying the monocrystalline silicon substrate, forming a monocrystalline compound semiconductor material on the first monocrystalline oxide film, forming a second monocrystalline oxide layer or layered compound semiconductor overlying the monocrystalline compound semiconductor material.
