Abstract: Implementations described herein reduce electron-hole pair generation due to silicon dangling bonds in pixel sensors. In some implementations, the silicon dangling bonds in a pixel sensor may be passivated by silicon-fluorine (Si—F) bonding in various portions of the pixel sensor such as a transfer gate contact via or a shallow trench isolation region, among other examples. The silicon-fluorine bonds are formed by fluorine implantation and/or another type of semiconductor processing operation. In some implementations, the silicon-fluorine bonds are formed as part of a cleaning operation using fluorine (F) such that the fluorine may bond with the silicon of the pixel sensor. Additionally, or alternatively, the silicon-fluorine bonds are formed as part of a doping operation in which boron (B) and/or another p-type doping element is used with fluorine such that the fluorine may bond with the silicon of the pixel sensor.

Abstract: An array of nanoscale structures over photodiodes of a pixel array improves quantum efficiency (QE) for shorter wavelengths of light, such as green light and blue light. The nanoscale structures may be used without high absorption (HA) structures (e.g., when the pixel array is configured only for visible light) or may at least partially surround HA structures (e.g., when the pixel array is configured both for visible light and near infrared light). Additionally, the array of nanoscale structures may be formed using photolithography such that the nanoscale structures are approximately spaced at regular intervals. Therefore, QE for the pixel array is improved more than if the array of nanoscale structures were to be formed using a random (or quasi-random) process.
