What you're buying is a bunch of X-Rays and Scanning Electron Microscope (SEM) photographs of the chip, including cross-sections of the devices, so competitors can see what Panasonic did to make it.

"The Device Essentials deliverable for imaging devices comprises a one page summary of observed device metrics and salient features. The summary is supported by the following unannotated image folders: • Downstream product teardown • Package X-rays, die photograph, non-invasive optical photos of die features • SEM imaging of the pixel array delayered to the metal, transistor, and diffusion levels • Exploratory cross-section SEM imaging of the general pixel array and peripheral structures This deliverable provides basic competitive benchmarking information and enables cost-effective tracking of multiple competitors’ technology."

E.g. see the second picture here:

Here's another example of what they do:

BTW it's very interesting Panasonic did them a custom one with PDAF, I guess they much think very highly of their defocus technique to use it on the GH4 instead of PDAF. As I plan to get a GH4 then hopefully it's the business...
