  We reconsider the holographic model featuring a superconducting dome on the
temperature-doping phase diagram with a modified view on the role of the two
charges. The first type charge with density $\rho_{A}$ make the Mott insulator,
and the second one with $\rho_{B}$ is the extra charge by doping, so that the
complex scalar describing the cooper pair condensation couples only with the
second charge. We point out that the key role in creating the dome is played by
the three point interaction $-c \chi^{2} F_{\mu\nu}G^{\mu\nu}$. The $Tc$
increases with their coupling. We also consider the effect of the quantum
critical point hidden under the dome using the geometry of hyperscaling
violation. Our results show that the dome size and optimal temperature increase
with $z$ whatever is $\theta$, while we get bigger $\theta$ for larger
(smaller) dome depending on $z>2$ ($z<2$). We also point out that the
condensate increases for bigger value of $\theta$ but for smaller value of $z$.
