Superconductors have zero electrical resistivity, however semiconductors have finite resistivity.
There is an electron electron attraction in superconductors which leads to the vanishing of resistivity, however electron electron repulsion in Semiconductors leading to the finite resistivity of semiconductors.
Superconductors shows perfect diamagnetism, however it is not always true for semiconductors.
Energy gap in superconductors is of the order of 10^-4 eV. However, in Semiconductors it is of the order of few eV.
Flux quantization in superconductors is in units of 2e, but in case of semiconductors it is in units of e.

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor.
