  • Patent number: 11107717
    Abstract: A cassette transport device is disclosed which includes a smart cart, a base expansion frame mounted on the smart cart and a cassette-loading frame fixed to the base expansion frame. The cassette-loading frame is partitioned into several segments each accommodating a plurality of cassette trays. Each of the cassette trays defines, on its surface, a first trough and a second trough in the first trough. The first trough is configured to retain a cassette of a first size, and the second trough is configured to retain a cassette of a second size. With the first and second troughs, each of the cassette trays is able to retain a cassette of either the first or second size, making the cassette transport device possible to be used in transportation of the both types of cassettes with a high yield. Moreover, the smart cart is capable of automated transportation without human intervention or track construction while enabling savings in transportation cost, time and labor.

  • Publication number: 20190152721
    Abstract: A robotic manipulator for handling a cassette and an automated cassette transport device are disclosed, the device including a mechanical arm (1), an end actuator (2) at an end of the mechanical arm (1) and a vision-based locating assembly (3) on the end actuator (2). On the one hand, the vision-based locating assembly (3) can determine the position of a flange of the cassette, thereby identifying the cassette. In other words, the cassette can be identified based on a feature of the cassette itself. This dispense with a separate locating marker while improving cassette measuring and handling accuracy. On the other hand, transportation of the cassette is allowed by complementary retention of its flange on a recessed surface of the end actuator (2).

  • Patent number: 9983488
    Abstract: An apparatus for correcting the shape of a reticle, including: suckers; a sucker mounting frame; and a pneumatic control system, wherein the sucker mounting frame is disposed above a reticle stage, the suckers are mounted on a bottom of the sucker mounting frame in a manner of being spaced apart from one another; and the pneumatic control system is configured to control the suckers to retain the reticle by suction or to release the reticle. The suckers are so arranged that they do not block trapezoidal exposure fields of view on the reticle, thereby allowing a light beam to be fully (100%) incident on the reticle, which results in improved exposure efficiency. The apparatus is mounted separately from a photolithography tool by which it is employed, enabling a lower weight load on the reticle. Additionally, the apparatus is not in contact with any component disposed in the photolithography tool and will not introduce additional external vibration to the tool.
