Well, there is a boundary between the P and N junction. Capacitance mostly become important when the junction is reverse biased and is not conducting. When reversed biased, a depletion layer is form at the junction and the thickness increase with the reverse voltage. Thanks for this part...

i have tried a lot but menacingly failed to understand how the parasitic capacitance exists in a pnp or npn transistor or at any diode??
