  • Publication number: 20080066679
    Abstract: A processing system is used for processing an object by a first fluid. The processing system includes a base and a plasma generation device. The base supports the object and the plasma generation device ionizes the first fluid. The plasma generation device includes at least one guiding element comprising a path guiding the first fluid to sequentially flow through a first position and a second position and at least one electrode element including a first electrode corresponding to the first position and a second electrode corresponding to the second position. The first and second electrodes energize the first fluid located between the first and second electrodes to form a second fluid, to thereby utilize the second fluid to perform surfacing, activating, cleaning, photoresist ashing or etching process on the object supported by the base.

  • Publication number: 20080030673
    Abstract: A method for fabricating liquid crystal (LC) alignment includes the steps of processing an alignment film having a plurality of liquid crystal molecules with a single or plurality of plasma generating devices, such that the liquid crystal molecules are aligned at a high pretilt angle. Compared with the prior art, the present invention is suitable for modifying the alignment film surface adjustablely in directions and angles, and can attain the effect of alignment stability with a high pretilt angle in a single process, thus overcoming the drawbacks of the prior art.

  • Patent number: 6821127
    Abstract: A socket assembly (1) includes a socket (2) and a vacuum pickup cap (3). The socket includes a base (20), a cover (21) movably assembled upon the base and an actuating rod (22) assembled on both the base and the cover for driving the cover to move in relative to the base. The cover defines a through hole (200) in a center thereof. The vacuum pickup cap includes a flexible bottom plate (31) and a flexible film (32). The flexible bottom plate has a sticky bottom surface (310) adhered to an upper surface of the cover and covering the through hole of the cover. The flexible film has a sticky bottom surface (320) adhered to the flexible bottom plate and a smooth upper surface (321) adapted for being sucked by a vacuum pickup device.
