Semiserious posted an interesting story on image sensor fakes having just one metal layers covered by color filters and microlens. The 10-device lot was acquired from Chinese distributor. It was supposed to be "a certain leading CMOS image sensor supplier’s device who is known to use a certain leading Asian fab to manufacture its devices" (Omnivision?).
A theory is discussed that this might be a mechanical testing lot somehow finding its way to a distributor. As more reverse engineering research is being done on it, the story might continue.
