The shape of electrodeposited nickel microprobes changed from a flat to an oval shape with the addition of propargyl alcohol in a nickel sulfamate bath ; propargyl alcohol is considered to have the function of the shape control. To research the effect of this organic additive on the function of the shape control, several alcohols having different structures, that is, states of carbon to carbon bonding, numbers of hydroxyl groups bonded to the terminal carbon, and numbers of carbons in the molecule, were investigated.From the result of preparing nickel microprobes electrodeposited from the bath containing the additive, an alcohol with a carbon-to-carbon triple bond and hydroxyl groups was effective to control the shape, and an alcohol without a triple bond did not have the function of shape control.
