Abstract:
A method for manufacturing a printer head using shape memory alloy, comprising the steps of:preparing a silicon substrate having a flat configuration; thermally oxidizing the silicon substrate to form a pair of silicon dioxide layers on both surfaces of the silicon substrate, respectively; forming a shape memory alloy layer on one of the pair of silicon dioxide layers by a semiconductor thin film forming process; thermally treating the formed shape memory alloy layer; patterning the shape memory alloy layer; patterning the silicon dioxide layers formed on both surfaces of the silicon substrate, respectively; forming an electrode on the shape memory alloy layer to have a desired pattern; forming an insulating layer for protecting the electrode; forming a body of the printer head by etching the silicon substrate on which the electrode and insulating layer are formed; separately forming a nozzle plate into which a plurality of nozzles are formed; forming a fluid passage plate by bonding a photosensitive dry film onto the nozzle plate and patterning the photosensitive dry film; and bonding the nozzle plate and the fluid passage plate onto the body of the printer head.
