Chipworks: Sony Switches to Bulk BSI in 1.1um Pixel

Chipworks is preparing the analysis of Sony’s latest 1.1um pixel sensor, the IMX081. Built on a 90 nm process, Sony has implemented a new pixel layout and schematic architecture, moving to an eight-shared pixel architecture (1.375T per pixel effective). One of the most interesting findings is that Sony has migrated to using bulk silicon substrates instead of SOI.

Here is the image (the smoking gun) that proves that Sony has indeed adopted a bulk Si process:

  1. eight-shared pixel architecture?
    does it impact the conversion gain value?
