The hybridization of Si in SiO2 is sp3.

Si : [Ne]3s23p2

SiO2 forms a covalent network in which the Si atoms form 4 single bonds to oxygen atoms. The oxygen atoms form 2 single bonds (and have two lone pairs) to Si atoms.

Si is in the same group as C but because it contains the d orbitals (empty but there), Si is two large to form pi bonds.
