Earlier quoted context omitted.
What technology are you referring to, specifically? Most large semiconductor companies these days are fabless (Qualcomm, AMD, NVIDIA), or just license their designs/IP (ARM, Imagination, Rambus). Fabless is not really a new thing, it's just a lot cheaper than most people imagine.
Derp, just got around to googling fabless semiconductor. I had assumed fabless meant a way of creating integrated circuits without expensive silicon processing facilities, clean rooms, etc... I imagined something like 3D printing/laser cutting for silicon chips.
That's sort of what a fab already is =)
