Fuji claims it is their own sensor. All this means is that they designed it, but it could well be fabbed anywhere. On the other hand, there are very few fabs capable of making sensors, and they may serve most of the camera companies at one time or another. Sony Semiconductor is one such fab, and they manufacture designs by anyone who comes to them, including Sony Camera. However, they are a separate company within the huge Sony conglomerate. If Fuji designed it and Sony Semiconductor manufactured it, it does not make it a Sony any more than a Nikon should be rebranded Mitsubishi, since they have the same relationship to their parent brand.
You could go to any of the fabs with a sensor design and a truckload of money and you will get exactly what you wanted. No matter if Toshiba or Sony or Panasonic did the fabrication, or all three, the sensor will be exactly what you ordered.
Realize that Not-Made-Here, while common in the western world, is uncommon in Japan. Intellectual property is freely licensed to rival companies and everyone makes stuff for everyone else. For the first many years, all Canon lenses were made by Nikon. Cosina manufactures for everyone. The Nikon FM10 is made by Cosina, and the camera has had cosmetic changes to be sold by Rollei, Olympus, Canon and a number of others. Most Carl Zeiss lenses are made at Cosina, as well as all things Voightlander and the Epson digital rangefinder. Minolta made the Leica CL. Fuji made the Hasselblad XPan, and is rumored to be making all Hasselblad H equipment presently. My German Plaubel Makina 67 was initially made by Copal, and later by Mamiya. Contax cameras were made by Kyocera, who also made Yashica. Vivitar lenses were made by Tokina, Cosina, Kiron, Komine, Samyang, Olympus, Kobori, and even Perkin-Elmer who built the Hubble Space Telescope. Samyang of South Korea also sells as Bower, Rokinon, Walimex and Pro-Optic. Fuji flashes are made by Sunpak.
This would be most unusual in the west, where most things are branded by the company who made the product. Most Japanese companies are part of a family, and the operate as traditional Oriental trading-companies, no matter how high-tech the product may be. If there is a gap in their product line-up and they don't have the capacity to manufacture it, they order from another manufacturer who makes it to their specification. Fuji flashes, though made by Sunpak—whose own line is fairly low-end—are in every way Fujis, since Fuji stands behind them. The fact that Hasselblad lenses are re-branded Fujinons is in general a very good thing.
