This is an awsome image:
This is an X-ray cross-section of the 8 megapixel camera in the new iPhone 4S. It was taken by the great folks at Chipworks. I encourage you to check out the original, high-resolution image. It's breathtaking.
Also thanks to Chipworks, we know who built the camera: Sony. This shot was taken using an infrared microscope that can look through the structure into the base layers of the chip. Can you read the lettering?
