  • Patent number: 10525166
    Abstract: The invention relates to a selenium-doped hydroxyapatite and a preparation method thereof. The selenium-doped hydroxyapatite provided is a single crystal comprising a rod-like structure, a uniform morphology, and a good dispersibility. The preparation method comprises adding a mixed solution of a phosphate and a selenite dropwise to a mixed solution of a calcium salt and a dispersing agent, and reacting for 1.5-2.5 hrs at a controlled temperature of 80-90° C., to obtain a solution of a calcium phosphate amorphous precursor, followed by performing a hydrothermal reaction at 190-210° C., to obtain a selenium-doped hydroxyapatite comprising a rod-like structure.
    Type: Grant

  • Patent number: 9209056
    Abstract: An overhead buffer device used for disposing in a semi-conductor factory includes a strut module and a plurality of buffer modules. The strut module disposed on the top wall of the factory has a horizontal beam and a plurality of overhead strut. The overhead strut is set on the horizontal beam and spaced arranged along the horizontal beam. The buffer modules are installed on the overhead strut respectively. Each buffer module has a plurality of buffers arranged in sequence and along a vertical direction. Each buffer is used for receiving one front opening unified pod (FOUP). Thus, the instant disclosure can be used for using the space of the factory efficiently. Besides, the instant disclosure also provides a wafer transport system having the overhead buffer device.
