Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: forming a first conductive layer on a semiconductor substrate; forming a magnetic film on the first conductive layer; forming a second conductive layer on the magnetic film; forming a first mask layer on the second conductive layer; patterning the second conductive layer using the first mask layer to form a patterned second conductive layer; patterning the magnetic film using the patterned second conductive layer to form a patterned magnetic film; forming a first insulating film on the first conductive layer to cover a side surface of the patterned second conductive layer and the patterned magnetic film; forming a second mask layer on the first insulating film to cover the patterned second conductive layer, the patterned magnetic film, and the first insulating film; patterning the first insulating film using the second mask layer to form a patterned first insulating film; patterning the first conductive layer using the patterned first insulating film to form a patterned first conductive film; forming a second insulating film on the semiconductor substrate to cover the patterned second conductive layer, the patterned magnetic film, and the patterned first conductive layer; and forming a third insulating film on the second insulating film.
