  • Patent number: 11201243
    Abstract: The current disclosure describes techniques for forming a gate-all-around device where semiconductor layers are released by etching out the buffer layers that are vertically stacked between semiconductor layers in an alternating manner. The buffer layers stacked at different vertical levels include different material compositions, which bring about different etch rates with respect to an etchant that is used to remove at least partially the buffer layers to release the semiconductor layers.

  • Patent number: 11171488
    Abstract: A solar power system may include a solar panel set, a lithium battery set, a first controller, and a second controller. A single-contact switch is electrically connected between the solar panel set and the lithium battery set.
