[quote name='Kaijufan']Does Sony make all of the parts of the PS2 (Processor, Ram, GPU, motheboard, etc) or does someone else make them for Sony?[/quote]
Originally Sony didn't have its own facilities for high-end chip production and hadn't really needed them. They got serious with the PS2. The engineering samples were all outsourced or done at partner Toshiba's plant. Since there has been a lot of integration of the chipset it's now probably all internal to Sony except for the RAM chips. I don't recall for sure but since it's RAMBUS it's either Toshiba or Hynix.
