Cobalt disilicide (CoSi₂) is an intermetallic compound combining cobalt and silicon, belonging to the family of transition metal silicides. It is primarily used in semiconductor and microelectronic applications as a contact material and silicide layer, where its low electrical resistivity and compatibility with silicon processing make it valuable for reducing contact resistance in integrated circuits. CoSi₂ is also explored in high-temperature structural applications and thermoelectric devices due to its thermal stability and metallic bonding characteristics, offering advantages over pure metals in scenarios requiring both electrical conductivity and resistance to oxidation.
