Sony Fab Tour

Dave Etchells from Imaging Resource publishes a nice overview of Sony image sensor fab. It describes a process of growing the silicon boules by Czochralski method in great details, then gets sketchy on photolitography and other FEOL and BEOL steps, then again goes into much more details on dicing, wire bonding, and packaging. While very simplistic, the article describes quite a complete process flow at Sony Kumamoto fab.

    Sony grows their own Si? Don't think so...

      Highly unlikely, probably getting wafers from SEH.

      "This is where the whole process begins, outside of Sony's factory at a company that grows the raw silicon."
