    摘要: A method for manufacturing a semiconductor device includes forming plural layers of a MTJ device, depositing a conductive layer over the plural layers, forming a hard mask pattern used for patterning the plural layers over the conductive layer, where the conductive layer is exposed through the hard mask pattern, performing hydrogen peroxide process to volatilize the exposed conductive layer and removing the volatilized conductive layer, and patterning the plural layers by using the hard mask pattern as an etch mask to form the MTJ device.
