The base tile is only equivalent with a miniaturized PCB that makes the connections between the other tiles. Its fabrication is much simpler than that of the other tiles and it belongs to the packaging and testing operations, which are done by Intel itself. It does not belong to the fabrication of the active parts of the CPU SoC. The Base Tile could have been fabricated by any from more than a dozen of IC manufacturers, while the active tiles are beyond the capabilities of any company besides TSMC, Samsung and Intel. The Base Tile is just "glue" for the tiles that contain the active devices.
