  • Patent number: 11955379
    Abstract: A metal adhesion layer may be formed on a bottom and a sidewall of a trench prior to formation of a metal plug in the trench. A plasma may be used to modify the phase composition of the metal adhesion layer to increase adhesion between the metal adhesion layer and the metal plug. In particular, the plasma may cause a shift or transformation of the phase composition of the metal adhesion layer to cause the metal adhesion layer to be composed of a (111) dominant phase. The (111) dominant phase of the metal adhesion layer increases adhesion between the metal adhesion layer.

  • Patent number: 11937903
    Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

  • Publication number: 20240096756
    Abstract: A method of making a semiconductor device includes manufacturing a first transistor over a first side of a substrate. The method further includes depositing a spacer material against a sidewall of the first transistor. The method further includes recessing the spacer material to expose a first portion of the sidewall of the first transistor. The method further includes manufacturing a first electrical connection to the transistor, a first portion of the electrical connection contacts a surface of the first transistor farthest from the substrate, and a second portion of the electrical connect contacts the first portion of the sidewall of the first transistor. The method further includes manufacturing a self-aligned interconnect structure (SIS) extending along the spacer material, wherein the spacer material separates a portion of the SIS from the first transistor, and the first electrical connection directly contacts the SIS.

  • Patent number: 8191231
    Abstract: A method for manufacturing an antenna includes steps as follows. First, a substrate is provided, wherein a surface of the substrate has an antenna region. Then, the surface of the substrate is electroless plated with a metal medium, so that the surface is covered with the metal medium. Then, the metal medium is covered with a resist. Then, a portion of the resist in the antenna region is removed. Then, the antenna region is electroplated with metal material to form an antenna main body. Then, a remaining portion of the resist is removed, and excluding a portion of the metal medium in the antenna region, the other portion of the metal medium is also removed from the substrate.
