  • Patent number: 11380542
    Abstract: Embodiments disclosed herein relate generally to capping processes and structures formed thereby. In an embodiment, a conductive feature, formed in a dielectric layer, has a metallic surface, and the dielectric layer has a dielectric surface. The dielectric surface is modified to be hydrophobic by performing a surface modification treatment. After modifying the dielectric surface, a capping layer is formed on the metallic surface by performing a selective deposition process. In another embodiment, a surface of a gate structure is exposed through a dielectric layer. A capping layer is formed on the surface of the gate structure by performing a selective deposition process.

  • Patent number: 11374127
    Abstract: A device, structure, and method are provided whereby an insert layer is utilized to provide additional support for weaker and softer dielectric layer. The insert layer may be applied between two weaker dielectric layers or the insert layer may be used with a single layer of dielectric material. Once formed, trenches and vias are formed within the composite layers, and the insert layer will help to provide support that will limit or eliminate undesired bending or other structural motions that could hamper subsequent process steps, such as filling the trenches and vias with conductive material.

  • Patent number: 10884519
    Abstract: The invention provides a scroll wheel module, which includes an adjustment wheel, a scroll wheel and a transmission mechanism. The adjustment wheel includes an adjustment portion. The scroll wheel includes a contact portion. The transmission mechanism has a first end and a second end opposite to each other, the first end is connected to the adjustment portion of the adjustment wheel, and the second end is adjacent to the scroll wheel. When the adjustment wheel is rotated, the first end of the transmission mechanism produces a displacement relative to the adjustment portion such that the second end of the transmission mechanism applies a force to the contact. A magnitude of the force is proportional to a rotational force of the scroll wheel.

  • Patent number: 10867762
    Abstract: A key structure is provided, including a key housing, a keycap, an elastic piece and a spring. The key housing comprises an interfering portion. The keycap is movably assembled to the key housing along a pressing axial direction. The elastic piece is movably assembled to the keycap along the pressing axial direction. The elastic piece comprises a protrusion, and the interfering portion is located on a movement path of the protrusion. The spring abuts between the keycap and the elastic piece. When in an initial position, the protrusion is stopped at the interfering portion. When an external force is applied to the keycap, in a pressing process, the keycap is moved relative to the key housing, and drives the protrusion to surmount and cross over the interfering portion. An elastic restoring force of the elastic piece causes the protrusion to hit the interfering portion to make a sound.
