  • Publication number: 20240414870
    Abstract: A connector for connecting to a first connecting member comprises a first supporting member, a second supporting member and an elastic member. A mounting hole is defined on the first supporting member for movable connecting to the first supporting member. The second supporting member is configured to be able to deflect axially relative to the first supporting member. The elastic member comprises a first ring body and a second ring body. A gap is defined between the first ring body and the second ring body for translating or deflecting the first ring body relative to the second ring body.

  • Publication number: 20240379423
    Abstract: A barrier layer is formed in a portion of a thickness of sidewalls in a recess prior to formation of an interconnect structure in the recess. The barrier layer is formed in the portion of the thickness of the sidewalls by a plasma-based deposition operation, in which a precursor reacts with a silicon-rich surface to form the barrier layer. The barrier layer is formed in the portion of the thickness of the sidewalls in that the precursor consumes a portion of the silicon-rich surface of the sidewalls as a result of the plasma treatment. This enables the barrier layer to be formed in a manner in which the cross-sectional width reduction in the recess from the barrier layer is minimized while enabling the barrier layer to be used to promote adhesion in the recess.
