  • System and method for removing foreign particles from semiconductor device
    Patent number: 8141570
    Abstract: A vibration device separates foreign particles from a semiconductor device, and a suction interface of a suction device covers an opening portion of the semiconductor device. A space connected with a vacuum passage and a communication passage is formed between the semiconductor device and the suction interface. The suction device suctions the space, and fresh air is introduced into the space through the communication passage. As a result, a current of air is generated from the communication passage to the vacuum passage, and foreign particles are suctioned and removed from the space.
    Type: Grant
