Is it possible for (W/L) of 0.18nm PMOS to become 989100?

Is it possible for (W/L) of 0.18nm PMOS to become 989100 ? If not,i wonder what the range is for (W/L) of TSMC 0.18nm PMOS and NMOS.Thanks a lot.

When designing a circuit with FETs you can generally make any W/L you want, but as I mentioned earlier, this might make the dimensions of your FETs undesirable. You can instead replace a FET of width W with the parallel combination of n FETs of width W/n as shown:
