  • Patent number: 11961770
    Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

  • Patent number: 6587324
    Abstract: A power-off protection device. The device outputs operating power according to a first level signal and a second level signal, and comprises a processor, a modulating circuit, a power generating circuit, and a reference-voltage maintenance device. The processor outputs a voltage modulating signal. The circuit is coupled to the processor and the first level signal to output a voltage control signal responding to the voltage modulating signal. The power generating circuit is coupled to the second level signal and the modulating circuit for generating operating power from the second level signal according to the voltage control signal. The reference -voltage maintenance device is coupled to the first level signal and the modulating circuit to delay the drop time of the first level signal to confirm that the first level signal is higher than the second level signal when the first level signal and the second level signal are turned off.
