No. TSMC spend enormous amount of money developing their processes. To implement them in the fab, they need and thus cooperate (and co-develop) with vendors. But TSMC is far from just integrating stuff. As an example, TSMC design their own gates, including how they are structured and created on the die. This means developing each process step.
