Abstract: An MRAM structure includes a dielectric layer. A first MRAM, a second MRAM and a third MRAM are disposed on the dielectric layer, wherein the second MRAM is disposed between the first MRAM and the third MRAM, and the second MRAM includes an MTJ. Two gaps are respectively disposed between the first MRAM and the second MRAM and between the second MRAM and the third MRAM. Two tensile stress pieces are respectively disposed in each of the two gaps. A first compressive stress layer surrounds and contacts the sidewall of the MTJ entirely. A second compressive stress layer covers the openings of each of the gaps and contacts the two tensile material pieces.

Abstract: A method for fabricating a semiconductor device includes the steps of first forming a magnetic tunneling junction (MTJ) on a substrate, forming a top electrode on the MTJ, forming an inter-metal dielectric (IMD) layer around the top electrode and the MTJ, forming a landing layer on the IMD layer and the MTJ, and then patterning the landing layer to form a landing pad. Preferably, the landing pad is disposed on the top electrode and the IMD layer adjacent to one side of the top electrode.

Abstract: A manufacturing method of a semiconductor device includes the following steps. A first stacked structure and a second stacked structure are formed on a core region and an input/output (I/O) region of a semiconductor substrate respectively. The first stacked structure includes a first patterned oxide layer, a first patterned nitride layer, and a first dummy gate. The second stacked structure includes a second patterned oxide layer, a second patterned nitride layer, and a second dummy gate. The first dummy gate and the second dummy gate are removed for forming a first recess above the core region and a second recess above the I/O region. A first gate structure is formed in the first recess and a second gate structure is formed in the second recess. The first patterned nitride layer is removed before the step of forming the first gate structure in the first recess.
