Abstract:
A method for fabricating semiconductor device includes the steps of: forming a first inter-metal dielectric (IMD) layer on a substrate; forming a magnetic tunneling junction (MTJ) on the first IMD layer; forming a liner on the MTJ and the first IMD layer; removing part of the liner to form a spacer adjacent to the MTJ; and forming a second IMD layer on the first IMD layer.

Claim (Index 1):
A method for fabricating semiconductor device, comprising:\n forming a first inter-metal dielectric (IMD) layer on a substrate; forming a metal interconnection in the first IMD layer; forming a magnetic tunneling junction (MTJ) stack on the first IMD layer and the metal interconnection; removing the MTJ stack, the first IMD layer, and the metal interconnection to form a MTJ directly on the metal interconnection, wherein a top surface of the first IMD layer adjacent to two sides of the MTJ comprises a curve forming a liner on the MTJ and the first IMD layer; removing part of the liner to form a spacer adjacent to the MTJ, wherein a sidewall of the spacer is aligned with a sidewall of the metal interconnection; and forming a second IMD layer on the first IMD layer.
