(disilanyl-disilyl-silyl)ytterbiumSilicon is more electropositive than carbon. In terms of their physical properties, silicides are structurally closer to borides than to carbides. Because of size differences however silicides are not isostructural with borides and carbides.Bonds in silicides range from conductive metal-like structures to covalent or ionic. Silicides of all non-transition metals have been described except beryllium. Silicides are used in interconnects.Silicon atoms in silicides can have many possible organizations:Isolated silicon atoms: electrically conductive (or semiconductive) CrSi, MnSi, FeSi, CoSi, Cu5Si, (V,Cr,Mn)3Si, Fe3Si, Mn3Si,Mg2(Si,Ge,Sn,Pb), (Ca,Ru,Ce,Rh,Ir,Ni)2Si,Si2 pairs: U3Si2, hafnium and thorium silicides,Si4 tetrahedra: KSi, RbSi, CsSi,Sin chains: USi, (Ti, Zr, Hf, Th, Ce, Pu)Si, CaSi, SrSi, YSi,Planar hexagonal graphite,like Si layers: β-USi2, silicides of other lanthanoids and actinoids,Corrugated hexagonal Si layers: CaSi2,Open three-dimensional Si skeletons: SrSi2, ThSi2, α-USi76,Most silicides are produced by direct combination of the elements.However, the process is extremely exothermic and control of the reaction poor. In rare cases, a metal oxide can undergo silicobaric reduction, in which pure silicon deoxygenates the metal to a silicon oxide, which is then removed by a vacuum. Alternatively, molten aluminum or copper are adequate solvents for the alloying.A silicide prepared by a self-aligned process is called a salicide. This is a process in which silicide contacts are formed only in those areas in which deposited metal (which after annealing becomes a metal component of the silicide) is in direct contact with silicon, hence, the process is self-aligned. It is commonly implemented in MOS/CMOS processes for ohmic contacts of the source, drain, and poly-Si gate.The transition metal silicides are usually inert to aqueous solutions. At red heat, they react with potassium hydroxide, fluorine, and chlorine. Mercury, thallium, bismuth, and lead are immiscible with liquid silicon.
