  • Patent number: 11959101
    Abstract: A cell activation reactor and a cell activation method are provided. The cell activation reactor includes a body, a rotating part, an upper cover, a microporous film, and multiple baffles. The body has an accommodating space, which is suitable for accommodating multiple cells and multiple magnetic beads. The rotating part is disposed in the accommodating space and includes multiple impellers. The microporous film is disposed in the accommodating space and covers multiple holes of the accommodating space. The baffles are disposed in the body. When the rotating part is driven to rotate, the interaction between the baffles and the impellers separates the cells and the magnetic beads.

  • Publication number: 20060202203
    Abstract: The invention provides a TFT electrode structure and its manufacturing method that can prevent metal diffusion occurring in the fabrication of a TFT, and thereby reduce the risk of contamination of the chemical vapor deposition process due to metallic ion diffusion. The transparent pixel electrode is formed after the gate electrode metal so that the pixel transparent electrode can be used as a barrier layer to prevent metal diffusion under high temperature from the gate electrode metal to adjacent insulating layers or the active layer. Further, the method used to form the transparent pixel electrode is a low-temperature physical vapor deposition process, which affected less by the processing environment, and the transparent pixel electrode is a conductive layer that is not affected by metal diffusion.
