  • Patent number: 9281178
    Abstract: A cleaning agent for a silicon wafer (a first cleaning agent) contains at least a water-based cleaning liquid and a water-repellent cleaning liquid for providing at least a recessed portion of an uneven pattern with water repellency during a cleaning process. The water-based cleaning liquid is a liquid in which a water-repellent compound having a reactive moiety chemically bondable to Si element in the silicon wafer and a hydrophobic group, and an organic solvent including at least an alcoholic solvent are mixed and contained. With this cleaning agent, the cleaning process which tends to induce a pattern collapse can be improved.

  • Patent number: 9111363
    Abstract: A video playback apparatus that processes an obtained video and plays back the processed video, includes: a face recognition unit which detects the size and position of an image of a person in the video, which change over time; a generation unit which generates a playback video for playback, such that the image of the person shown in the playback video is of a predetermined size, by (i) determining a clipping range for a part of the video in response to a change in the detected position, and (ii) enlarging or reducing, in response to a change in the detected size, a partial video which is the part of the video shown in the clipping range; and a video playback unit which plays back the generated playback video. Here, the response time for the clipping range determination is longer than a response time for the partial video enlargement or reduction.
