  • Publication number: 20170018706
    Abstract: Embodiments of the disclosure provide methods and apparatus for fabricating magnetic tunnel junction (MTJ) structures on a substrate in for spin-transfer-torque magnetoresistive random access memory (STT-MRAM) applications. In one embodiment, the method includes patterning a film stack having a tunneling barrier layer disposed between a magnetic reference layer and a magnetic storage layer disposed on a substrate to remove a portion of the film stack from the substrate until an upper surface of the substrate is exposed, forming a sidewall passivation layer on sidewalls of the patterned film stack and subsequently performing a thermal annealing process to the film stack.

  • Publication number: 20160351799
    Abstract: Device structures and methods for fabricating device structures are provided herein. Magnetic random access memory (MRAM) devices described herein may include a film stack comprising a magnetic tunneling junction layer, a dielectric capping layer, an etch stop layer, a conductive hard mask layer, a dielectric hard mask layer, a spin on carbon layer, and an anti-reflective coating layer. The film stack may be etched by one or more selected chemistries to achieve improved film stack sidewall verticality. Memory cells having increasingly uniform and reduced critical dimensions may be fabricated utilizing the methods and devices described herein.

  • Publication number: 20150255507
    Abstract: A method for fabricating an MRAM bit that includes depositing a spacer layer that protects the tunneling barrier layer during processing is disclosed. The deposited spacer layer prevents byproducts formed in later processing from redepositing on the tunneling barrier layer. Such redeposition may lead to product failure and decreased manufacturing yield. The method further includes non-corrosive processing conditions that prevent damage to the layers of MRAM bits. The non-corrosive processing conditions may include etching without using a halogen-based plasma. Embodiments disclosed herein use an etch-deposition-etch sequence that simplifies processing.

  • Patent number: 8985545
    Abstract: A supporting assembly is disposed to a case of an electronic device. A window is formed on the case for communicating an inner surface and an outer surface of the case. The supporting assembly includes a fixed part, a latching post, and a support body. The fixed part is disposed to the inner surface. The latching post includes a fixing end and an inserting end. The fixing end runs through the window and is fixed to the fixed part. A first stopping block is disposed to the inserting end. The support body includes a supporting side and a combination side. A combination hole is formed at the combination side for the inserting end to insert therein. The support body further includes a second stopping block protrudly disposed in the combination hole, for stopping the first stopping block to prevent the inserting end from escaping from the combination hole.

  • Patent number: 8866033
    Abstract: An electronic device includes a case and a key module. The key module is mounted on a supporting surface of a housing of the case and includes: a touch pad, a circuit board, a press switch and a transmission member. The press switch is coupled electrically to the circuit board and is disposed at a position corresponding to the middle of the touch pad in a lengthwise direction. The transmission member is mounted between the circuit board and the supporting surface, and includes two levers and a press member disposed between the levers and abutting against the press switch. A corresponding electrical signal can be produced by abutment of the press member against the press switch linked by the transmission member.
