Abstract: A pixel sensor includes a transfer fin field effect transistor (finFET) to transfer a photocurrent from a photodiode to a drain region. The transfer finFET includes at least a portion of the photodiode, an extension region associated with the drain region, a plurality of channel fins, and a transfer gate at least partially surrounding the channel fins to control the operation of the transfer finFET. In the transfer finFET, the transfer gate is wrapped around (e.g., at least three sides) of each of the channel fins, which provides a greater surface area over which the transfer gate is enabled to control the transfer of electrons. The greater surface area results in greater control over operation of the finFET, which may reduce switching times of the pixel sensor (which enables faster pixel sensor performance) and may reduce leakage current of the pixel sensor relative to a planar transfer transistor.

In this way, when the air interface user plane key is used to securely transmit service data, security of service data transmission over an air interface can be improved.

Abstract: Some implementations described herein provide pixel sensor configurations and methods of forming the same. In some implementations, one or more transistors of a pixel sensor are included on a circuitry die (e.g., an application specific integrated circuit (ASIC) die or another type of circuitry die) of an image sensor device.
