  • Publication number: 20180074913
    Abstract: A storage control device includes a processor which performs first copy of copying first data stored in a first storage device into a first backup region upon detecting a failure presage in the first storage device. The processor performs first write of writing second data specified in a first write request to the first storage device and second write of writing the second data into the first backup region upon receiving the first write request while performing the first copy. The processor performs second copy of copying third data stored in the first backup region to a second storage device upon completing the first copy. The processor performs third write of writing fourth data specified in a second write request to the second storage device in place of the first storage device upon receiving the second write request after completion of the second copy.

  • Patent number: 9824919
    Abstract: There is provided a method of filling a recess with a germanium-based film composed of germanium or silicon germanium in a substrate to be processed on which an insulating film having the recess formed therein is formed, the method including: forming a silicon film on a surface of the insulating film at a thickness as not to completely fill the recess; subsequently, etching the silicon film such that the silicon film remains only in a bottom portion of the recess; and subsequently, selectively growing the germanium-based film composed of germanium or silicon germanium on the silicon film remaining in the bottom portion of the recess and selectively filling the recess with the germanium-based film.
