  • 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.

  • Publication number: 20060092449
    Abstract: A printing device including a first memory unit, a second memory unit, a printing unit and a control unit is provided. The control unit is for receiving print data and then creating at least a print signal, and for controlling the printing unit to print the print data. The first memory unit and the second memory unit are for receiving and storing the print data from the control unit according to the print signal. The control unit transmits the print data to the first memory unit when the print signal does not comprise a manual print signal and to the second memory unit when the print signal comprises the manual print signal and controls the printing unit to automatically print the print data stored in the first memory unit and to manually print the print data stored in the second memory unit.

  • Publication number: 20060039035
    Abstract: A fax device comprising a tray, a detecting unit, a faxing unit, a controlling unit and a printing unit is provided. The tray is for accommodating a printing medium. The faxing unit is for receiving fax image data with a page size. The detecting unit is for detecting size of the printing medium. The controlling unit is for processing the fax image data, according to the page size and the size of the printing medium, into a print image data with a print frame whose size is equal to or smaller than the size of the printing medium. The controlling unit is for controlling the printing unit to print the print image data onto the printing medium.

  • Publication number: 20050251016
    Abstract: An image acquiring device and method of rotating images includes a scanning module, a driving mechanism, a selecting module, a control-processing unit and a memory. The scanning module scans a plurality of originals in sequence in conjunction with the driving mechanism. The selecting module selects a specific mark of a first original as a basis for judging an orientation state of a second original. The control-processing unit generates a digital mark signal stored in the memory according to the signals output from the scanning module and the selecting module. The control-processing unit judges a position of the digital mark signal in a digital signal obtained after the second original is scanned, and thus generates a rotating signal and rotates the digital signal into a normal image signal according to the rotating signal. Thus, the document image may be automatically rotated into a normal state.
