    CMOS technology is shown in Fig. 1(a). The PMOS transistor is located in a deep, lowly doped n-well that serves as its bulk. The NMOS, on the contrary, is located directly on the p-substrate material. The opposite is true for p-well CMOS technology (see Fig. 1(b)).

    The next step in the CMOS process flow is the formation of the active area n- and p-wells. These wells are formed in the open substrate surface areas defined by the shallow trenches. In the first step of well formation, a photoresist is deposited and patterned (as described above) so that the n-well area is masked and the p-well area is exposed.

  • Lecture 1. CMOS PROCESS

    For n-well CMOS process, the bulk of the PMOS is the n-well. It is isolated from the substrate and thus can be connected to the source. On the other hand, the bulk of the NMOS is the substrate itself and thus the bulk of the NMOS can’t be connected to the source. If you do, all the sources of the different NMOS transistors will be connected to each other. The opposite is true for p-well CMOS technology (see Fig. 1).
