    Which of the following statements concerning IC fabrication is not correct?

    Options :-

    1. A typical wafer of doped Si may be 400 µm thick, of diameter 5 – 15 cm. The purity of the wafer does not matter and can be even polycrystalline in nature.
    2. Semiconductors lack magnetic properties, so they cannot exhibit inductance. However, the inductors can be realized by combination of active and passive components.
    3. Resistors are obtained by utilizing the bulk resistivity of one of the regions; for example, the DS channel of MOSFET can serve as a resistor.
    4. In a reverse biased p-n junction, the positive and negative ions exist in opposite sides of p-n junction; because of that p-n junction behaves like a parallel plate capacitor.
