Abstract:
1. A method for manufacturing an integrated circuit structure with a magnetoresistance component, comprising: providing a substrate; forming a circuit structure layer on the substrate, the circuit structure layer comprising a metal pad; forming a dielectric layer on the circuit structure layer; forming a metal damascene structure in the dielectric layer; forming an opening in the dielectric layer so as to form a step-drop; after forming the metal damascene structure and the opening, forming a magnetoresistance material layer on the dielectric layer; and applying a photolithography process to pattern the magnetoresistance material layer to form a magnetoresistance component electrically connected to the metal damascene structure; conformally forming a passivation layer on the dielectric layer so as to cover the magnetoresistance component and to fill into the opening; and removing the passivation layer and the dielectric layer above the metal pad so as to expose the metal pad.
