  • Patent number: 11965237
    Abstract: A system and a method for detecting abnormality of a thin-film deposition process are provided. In the method, a thin-film is deposited on a substrate in a thin-film deposition chamber by using a target, a dimension of a collimator mounted between the target and the substrate is scanned by using at least one sensor disposed in the thin-film deposition chamber to derive an erosion profile of the target, and abnormality of the thin-film deposition process is detected by analyzing the erosion profile with an analysis model trained with data of a plurality of erosion profiles derived under a plurality of deposition conditions.

  • Publication number: 20230213046
    Abstract: An input device assembly with a support pad is provided. The input device assembly includes the support pad and an input device. The support pad includes a first main body and a first magnetic attraction element. The first main body has a first bottom surface and a first curvy surface. The input device includes a second main body and at least one second magnetic attraction element. The second main body has a second bottom surface and a second curvy surface. The first curvy surface of the support pad is contactable with one of plural portions of the second curvy surface of the input device. The first magnetic attraction element and one of the at least one second magnetic attraction element are magnetically attracted by each other. Consequently, the support pad is in close contact with the input device.

  • Patent number: 11309725
    Abstract: A support base includes a casing, a signal transmission module, a connection port, an audio output element and a detecting module. The support base is connected with a portable electronic device through the signal transmission module. The support base is connected with an external electronic device through the connection port. A first audio signal from the portable electronic device or a second audio signal from the external electronic device can be played by the audio output element. The detecting module detects the connection status of the support base. According to the connection status, the first audio signal or the second audio signal is controlled to be outputted from the audio output element.
