  • Patent number: 11605777
    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 stress pieces.

  • Patent number: 9669525
    Abstract: A palm wrench includes a C-shaped body and a driving head. The driving head is pivotably and rotatably located within the body. The body has an opening, and the driving head has two function ends on two sides thereof. The driving head is pivotably connected to the body by two pivots which extend through the body and are connected to the driving head. The driving head can be rotated with respect to the body, and the user can grapes the body to rotate the driving head to output torque.

  • Publication number: 20050158897
    Abstract: A method of fabricating an image sensor device is disclosed. In the method, a substrate having a plurality of trenches therein is provided. A first anti-reflective layer is formed on the surfaces of the trenches. An insulating layer is filled in the trenches for forming a plurality of shallow trench isolation regions. At least one photo sensitive region is formed within the substrate between neighboring shallow trench isolation regions. A second anti-reflective layer is formed at least covering the photo sensitive region. Because the first anti-reflective layer is formed on the surfaces of the trenches, and the second anti-reflective layer is formed on the photo sensitive region, the sensitivity of the image sensor device is improved.
