Patent ID: 8277667

Claim:
A method for manufacturing a magnetic element having an actuation part and a reinforcing structure, comprising steps of: (a) providing a substrate having a first surface and a second surface; (b) forming a passivation layer having a first specific area and a second specific area on the first surface; (c) forming an electroplate-initializing layer on the second surface; (d) forming a first photoresist layer having a third specific area on the electroplate-initializing layer; (e) forming a layer of a magnetic-inductive material on the third specific area, wherein the magnetic-inductive material is selected from a group consisting of a nickel, a nickel cobalt alloy and a nickel iron alloy; (f) forming a second photoresist layer on the second specific area of the first surface of the substrate and on the passivation layer; (g) removing a part of the substrate on the first specific area and the second photoresist layer to form a pattern for the magnetic element on the first surface and then removing the first photoresist layer and a part of the electroplate-initializing layer to form the actuation part having the formed layer of the magnetic-inductive material and a portion of the electroplate-initializing layer on the second surface; (h) etching the substrate to present the reinforcing structure for the magnetic element; and (i) removing the passivation layer to form the magnetic element.
