摘要：
A double-junction complimentary metal-oxide-semiconductor (CMOS) filterless color imager cell is provided. The imager cell is fabricated from a silicon-on-insulator (SOI) substrate including a silicon (Si) substrate, a silicon dioxide insulator overlying the substrate, and a Si top layer overlying the insulator. A photodiode set is formed in the SOI substrate, including a first and second photodiode formed as a double-junction structure in the Si substrate. A third photodiode is formed in the Si top layer. A (imager sensing) transistor set is formed in the top Si layer. The transistor set is connected to the photodiode set and detects an independent output signal for each photodiode. The transistor set may be an eight-transistor (8T), a nine-transistor (9T), or an eleven-transistor (11T) cell.
