Why dont you use carbon instead of silicon in making chips?
When considering the valency electrons C and Si both has 4.But the valency shell in C is closed to the nucleus. Therefore the bond is tight. C-C makes crystal bond. Therfore no free electrons or holes to carry currunt. So C is not commonly used as a semiconductor.

When the valency of calcium is 2 plus and the valency of carbide is 4- how does calcium carbide get the formula CaC2?
CaO + 3C >> CaC2 + COThis reaction can not be produced at a normal temperature achieved by combustion, but in an electric arc furnace. I can find out no more than that.Added:because the 'valency' of carbide is NOT uniqely -4: Actually in metal salts it's ion is (C2)2- , so with Ca2+ it forms CaC2The structural formule is not C-Ca-C but -Ca-(C=C)- formed in a chain with a triple bond between the Carbon atoms: ..... -Ca-C---C-Ca-C---C-Ca-..... etc.Even in ethyn H2C2 it is considered to have a -2 valency, though this is not a ionic (metal) salt.
