Abstract
An embodiment method for manufacturing a droplet-discharging head substrate may include a first step to perform a surface activation process on joint surfaces of first and second plates with an atom beam, ion beam or plasma; a second step to align and stack the first and second plates in such a manner that nozzle holes formed in the first plate communicate with through-holes formed in the second plate; and a third step to bond the joint surfaces of the stacked first and second plates by atomic bonding without covalent bonding caused by ion movement. The third step bonds the joint surfaces by bringing a load member into contact with the droplet-discharging surface of the first plate at a position away from the nozzle holes to apply pressure under an atmospheric pressure and by bringing the joint surfaces close to each other with an electrostatic attractive force.
