Abstract

A method for fabricating semiconductor device includes the steps of: forming a first magnetic tunneling junction (MTJ) on a substrate; forming a first liner on the MTJ; forming a second liner on the first liner; forming an inter-metal dielectric (IMD) layer on the MTJ, and forming a metal interconnection in the IMD layer, the second liner, and the first liner to electrically connect the MTJ. Preferably, the first liner and the second liner are made of different materials.
