Can I ask Diogenese, regarding the patient here mentioning Anolog NN, does that mean BRN are excluded do you think from this Sony deal ?.Sony have a patent for a 3D pixel in which a layer of photovoltaic sensor elements of the pixel are deposited over a layer of processing circuitry, effectively doubling the surface of PV sensors in comparison with the existing system in which the processing circuitry and PV sensors are co-planar,
WO2022044553A1 SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE
View attachment 66228
a semiconductor device in which a plurality of semiconductor chips 160, 140, 130) are stacked, the semiconductor device having enhanced functionality while reducing manufacturing cost. The semiconductor chips include a light-receiving chip (130), a redistribution wiring-side semiconductor chip (160), an intermediate semiconductor chip (140), a through-electrode (171), and redistribution wiring (141). The light-receiving chip receives incoming light. A wiring layer is formed on a predetermined wiring surface of the redistribution wiring-side semiconductor chip. One of a pair of joint surfaces of the intermediate semiconductor chip is joined to the light-receiving chip, and the other is joined to the redistribution wiring-side semiconductor chip. The through-electrode extends through a semiconductor substrate of the intermediate semiconductor chip. The redistribution wiring is wired on a wiring surface and connects the through-electrode and the wiring layer.
The intermediate semiconductor chip 140 includes a wiring layer 141 and a semiconductor substrate 142. The wiring layer 141 is formed on the upper surface of the semiconductor substrate 142. Further, the wiring layer 141 of the intermediate semiconductor chip 140 is joined to the wiring layer 133 of the light receiving chip 130. The thick dotted line in the figure indicates the joint surface. The intermediate semiconductor chip 140 is provided with, for example, a memory for holding image data and a signal processing circuit for processing the image data.
Sony have opted for analog NNs:
US2022020757A1 SEMICONDUCTOR STORAGE DEVICE AND NEURAL NETWORK DEVICE
A convolution neural network device is one of semiconductor storage devices, and includes a synapse circuit that performs multiply-accumulate operation and a buffer memory or the like that temporarily holds a multiply-accumulate operation result.
A neural network device according to one embodiment of the present disclosure includes a substrate, a first storage element, and a second storage element. The first storage element is formed on the substrate and includes a first insulating film. The first storage element functions as a buffer memory that temporarily stores a multiply-accumulate operation result. The second storage element is formed on the substrate and includes a second insulating film having a film thickness of equal to or greater than 0.5 times and equal to or less than 2 times a film thickness of the first insulating film. The second storage element differs from the first storage element in power consumption at a time of writing and functions as an analog multiplier-accumulator.
