How is a chip like this actually manufactured? Especially the analogue components area.

• kens 2y ago
  It's manufactured pretty much the same as any other chip, using photolithography. Most of the analog components would be CMOS transistors, just larger. They might use a BiCMOS process with a few extra steps to make bipolar transistors. And there might be an extra step for the capacitors. But overall, the chip uses an old, simple manufacturing process, much easier than cutting-edge processors.

    The chip seems like it's almost too small? I don't even know how they would cut up the wafer and how they would pick each die and mount it in the paper card.

      They cut the wafer apart with a diamond blade, 20 µm thick. Laser cutters can make thinner cuts, but they cost more. Die pick-and-place machines can manipulate even smaller dies at high speed: https://www.syagrussystems.com/dts-2-die-sorter https://www.syagrussystems.com/dts-2-die-sorter
