  • Patent number: 11985905
    Abstract: A magnetic tunneling junction (MTJ) structure comprises a pinned layer on a bottom electrode. a barrier layer on the pinned layer, wherein a second metal re-deposition layer is on sidewalls of the barrier layer and the pinned layer, a free layer on the barrier layer wherein the free layer has a first width smaller than a second width of the pinned layer, a top electrode on the free layer having a same first width as the free layer wherein a first metal re-deposition layer is on sidewalls of the free layer and top electrode, and dielectric spacers on sidewalls of the free layer and top electrode covering the first metal re-deposition layer wherein the free layer and the top electrode together with the dielectric spacers have a same the second width as the pinned layer wherein the dielectric spacers prevent shorting between the first and second metal re-deposition layers.

  • Publication number: 20240099151
    Abstract: A first conductive layer is patterned and trimmed to form a sub 30 nm conductive via on a first bottom electrode. The conductive via is encapsulated with a first dielectric layer and planarized to expose a top surface of the conductive via. A second conductive layer is deposited over the first dielectric layer and the conductive via. The second conductive layer is patterned to form a sub 60 nm second conductive layer wherein the conductive via and second conductive layer together form a T-shaped second bottom electrode. MTJ stacks are deposited on the T-shaped second bottom electrode and on the first bottom electrode wherein the MTJ stacks are discontinuous. A second dielectric layer is deposited over the MTJ stacks and planarized to expose a top surface of the MTJ stack on the T-shaped second bottom electrode. A top electrode contacts the MTJ stack on the T-shaped second bottom electrode plug.

  • Patent number: 11930715
    Abstract: A conductive via layer is deposited on a bottom electrode, then patterned and trimmed to form a sub 20 nm conductive via on the bottom electrode. The conductive via is encapsulated with a first dielectric layer, which is planarized to expose a top surface of the conductive via. A MTJ stack is deposited on the encapsulated conductive via wherein the MTJ stack comprises at least a pinned layer, a barrier layer, and a free layer. A top electrode layer is deposited on the MTJ stack and patterned and trimmed to form a sub 30 nm hard mask. The MTJ stack is etched using the hard mask to form an MTJ device and over etched into the encapsulation layer but not into the bottom electrode wherein metal re-deposition material is formed on sidewalls of the encapsulation layer underlying the MTJ device and not on sidewalls of a barrier layer of the MTJ device.

  • Patent number: 11921971
    Abstract: A live broadcasting recording equipment, a live broadcasting recording system and a live broadcasting recording method are provided. The live broadcasting recording equipment includes a camera, a processing device, and a terminal device. The camera captures images to provide photographic data. The processing device executes background removal processing on the photographic data to generate a person image. The terminal device communicates with the processing device and has a display. The processing device executes multi-layer processing to fuse the person image, a three-dimensional virtual reality background image, an augmented reality object image, and a presentation image, and generate a composite image. After an application gateway of the processing device recognizes a login operation of the terminal device, the processing device outputs the composite image to the terminal device, so that the display of the terminal device displays the composite image.

  • Patent number: 9413865
    Abstract: A handheld electronic device is provided, which includes a body and a key layout. The body has a base surface. The key layout is disposed on the base surface of the body and includes a plurality of keys. The key layout is a QWERTY key layout and the keys are adapted for users to press with their left or right thumb while holding the body in single hand or both hands. Each key has a curved surface protruded from the base surface and each curved surface has an inflection point. A distance between two inflection points of the curved surfaces of any two adjacent keys is greater than a distance between two figure centers of the orthogonal projections on the base surface of the curved surfaces of the two adjacent keys.
