  • Patent number: 7383156
    Abstract: It is possible to inspect scratches and staining on a wafer surface on the basis of an LPD map obtained from a particle counter 11, by providing a means 21 for detecting aggregation of clustered point defects (LPD) from two-dimensional distribution information 30 for such fine LPD on the surface of a silicon wafer, and an improvement in the inspection efficiency and the precision of judgements of “defective” status can be achieved. Furthermore, the system is devised so that the trend of generation of scratches and staining in a specified process can easily be detected by accumulating wafer surface information such as scratch information, staining information and the like for the wafer surface detected by a wafer surface inspection device 11 (especially as image information or numerical information), and superposing sets of information thus accumulated. Plans for improving processes can be made by both the wafer supplier and wafer consumer by sharing such information with both parties.

  • Patent number: 6248973
    Abstract: In a laser marking method for making a dot mark on a semiconductor wafer by using laser beam, molten splashes which arise at the laser marking are prevented from adhering to a surface of the wafer and a shape of the dot mark is kept in a stable posture with its visibility being ensured even after the marking made throughout various and multistage steps in a manufacturing process by the semiconductor apparatus. The method comprises forming a transparent thin film on at least a dot mark-formation area of a semiconductor wafer body of the wafer; irradiating the dot mark-formation area with laser beam having a wavelength selected in advance, on the transparent thin film; melting and deforming the wafer body by the laser beam transmitting the transparent thin film to form a dot mark; and by utilizing the heat generated when the wafer body is melted, deforming the transparent thin film, along with the deformation of the dot mark, into the same shape as the dot mark without a breakdown of the transparent thin films.

  • Patent number: 5895588
    Abstract: A controller for controlling a laser marking machine, which classifies a divided image into a non-printing region (H row) and a printing region ("APPER"). When the non-printing region is displayed on a liquid crystal display screen, the printing pattern ("APPER") is displayed on the liquid crystal screen so that scanning on the liquid crystal display screen is started by a scanning device from the printing region continuing the non-printing region by omitting this non-printing region (H row) when it is in an upper region for which scanning is first made. A moving device corrects the moving distance of the printing position of the printing pattern by the distance corresponding to the non-printing region (H row) so omitted, and starts movement to the marking position of the next divided image (B'3) when scanning of the printing region of this divided image (B'2) is finished.

  • Patent number: 5896163
    Abstract: A laser liquid crystal marker and a method of judging deterioration of the liquid crystal make it possible to maintain high printing accuracy, ascertain the proper time for replacement of liquid crystal and, further, maintain high printing accuracy even when high speed printing is continuously performed. The marker has a temperature sensor (4), light emitting means (5), light receiving means (6), and a controller (7). The controller (7) calculates a light transmittance (Qi) from the irradiation quantity of light (R1) of the light emitting means (5) and the transmitted quantity of light (R2) received by the light receiving means (6), and adjusts the applied voltage (Vi) of the liquid crystal (2) so that the light transmittance (Qi) becomes equal to an optimum light transmittance (Qo), stored in advance.

In another embodiment a plurality of masks and a second optical system for combining the beams from the masks can be used to create the mark. The system can be used with a conveyor and a loading and unloading unit using a controller.

  • Patent number: 5760370
    Abstract: An image display method for a liquid crystal mask marker displays an image of a high sharpness even when the marking speed is high. To this end, when the display image of a liquid crystal mask (4) is to be rewritten, the method includes performing at least one of (a) making all of the opaque picture elements (B) of the current image (P1) to become transparent, and (b) making all of the transparent picture elements (A) of the current image (P1) to become opaque; then making the electrodes of all of the picture elements (A,B) to be grounded or set equipotentially; and then starting the display of the next image (P2).
