Sony hybrid organic & inorganic sensor patent, the patent describes the sensor is made up of both organic and inorganic materials, the major details below
Translated by google
Sony patents pending on the imaging element of the hybrid formula that combines the benefits of both organic and inorganic materials. Also excellent resolution, there is no false colors since it does not require further OLPF In addition, the high sensitivity superior to be done by the organic photoelectric conversion layer. The organic layer is not suitable as high-speed readout, inorganic layer is done in the movement of the charge, seems to have and also allows high-speed readout. It might have appeared to great imaging element in the future.

official patent description:
In recent single-lens reflex digital cameras, a display such as a liquid crystal display (LCD) panel is disposed on the back of a camera body such that an image inputted to an image pickup device can be viewed using the display. For example, there has been proposed a single-lens reflex digital camera, having no optical viewfinder, that allows a user to take photographs while the user checks an image using a display disposed on the back of a camera body. In such a structure, an autofocus detecting device is disposed at an upper position in the camera body and light reflected by a light-beam splitting mirror can be guided to the autofocus detecting device. However, when light-beam splitting mirrors disclosed in Patent Documents 1 to 4 are used, the light quantity of transmitted light guided to an image sensor is increased compared with that of reflected light to improve the quality of photographed images. As a result, the light quantity of photographing light guided to an autofocus detecting device becomes insufficient.“….”The present invention can provide a light-weight small-size digital camera.”
And there is one more interesting news. Depending on the light wavelength the mirror reflects more or less light: “A sufficient quantity of subject light can be guided to an autofocus detecting device by adjusting the reflectivity to light with a wavelength to which the autofocus detecting device has high sensitivity to 25% or more and 35% or less, which can solve a problem in that light quantity becomes insufficient for autofocus detecting“…”When autofocus auxiliary light is used to perform photographing on a subject having a low contrast or in a dark place, the returned light out of the autofocus auxiliary light can be reflected at a reflectivity higher than that of light having a different wavelength and guided to the autofocus detecting device.
