  • Patent number: 7384811
    Abstract: With respect to a work obtained by joining a semiconductor wafer and a supporting member to each other via a both-faced adhesive sheet having heating separability, the surface of the supporting member is suction-held at a suction stage and is heated, thereby making the adhesive strength of an adhesive layer almost disappear. A Bernoulli chuck is moved close from the back side of the semiconductor wafer to separate the semiconductor wafer in a non-contact manner and to suspension-hold the semiconductor wafer in a state where the semiconductor wafer floats in the air.

  • Publication number: 20080099253
    Abstract: In a panel (1a) of a touch panel (1), a coordinate axis x is set by connecting points A and B that are current observation points. When a designated point P is designated on the panel (1a), currents (i1) and (i2) corresponding respectively to a distance between the designated point P and the point A and a distance between the designated point P and the point B flow respectively to a resistive film between the points P and A and a resistive film between the points P and B by voltage sources (e1) and (e2), and a sum of these currents flows to an impedance Z connected to the designated point P. A coordinate x of the designated point P is calculated by detecting the currents (i1) and (i2).

  • Publication number: 20080066869
    Abstract: In a state that a reference plane of a cutter holder, to which a cutter blade is attached, is brought into contact with a surface of a base of a supporting adhesive tape, the cutter blade cuts the supporting adhesive tape while the reference plane of the cutter holder follows the surface of the base. Herein, a cutting edge of the cutter blade passes by a joining interface between the supporting adhesive tape and a ring frame without penetrating through an adhesive layer of the supporting adhesive tape.

  • Publication number: 20060219359
    Abstract: During relative and horizontal movement of a mount frame, in which a semiconductor wafer with a protective tape is supported on a ring frame through a supporting adhesive tape, and a joining member, a position of an end edge of the protective tape is detected in a non-contact manner. Based on the detection result, a joining member is stopped in the position of the end edge of the protective tape and is moved close to the semiconductor wafer to press and bring a separation tape against and into contact with an end of the protective tape. In this state, the mount frame and the joining member are relatively and horizontally moved to join the separation tape onto the protective tape. Then, the mount frame and the joining member are relatively and horizontally moved to separate the separation tape together with the protective tape from a surface of the semiconductor wafer.

  • Patent number: 7078316
    Abstract: A joining roller rolls on the surface of a reinforcing substrate held by a center and side latch claws so as to be close and opposite to an wafer placed and held on a holding table in the condition that an adhesive sheet is adhered on the surface, whereby joining proceeds. As the joining roller rolls, both of the latch claws oscillate downward and the latch claws themselves move down while keeping the bend of the reinforcing substrate nearly constant, and retract when the joining roller approaches the latch claws.

  • Publication number: 20050215033
    Abstract: The invention relates to a semiconductor wafer dicing method of dicing a semiconductor wafer along parting lines into chips. The semiconductor wafer in which parting lines along which the semiconductor wafer is diced into chips are formed is held by an adhesive tape. By radially drawing the adhesive tape in a state where the chips in the semiconductor wafer are not parted from each other, the chips are parted from each other and clearances among the chips are extended.

  • Publication number: 20050032332
    Abstract: A work is suction-held by an upper suction chuck stage from the surface side of a supporting member, is moved upward to a predetermined height, and is heated in a state where the thickness direction of a both-faced adhesive sheet is not restricted, and a dicing tape is cooled. After lapse of predetermined heating time, the work is separated from the both-faced adhesive sheet whose adhesive strength is weaken, and drops to a lower suction chuck stage.

  • Publication number: 20040217945
    Abstract: A display device with a touch sensor according to the present invention includes an active matrix substrate 4A and a transparent counter electrode 7. On a first surface of the active matrix substrate, multiple pixel electrodes are arranged in matrix. The transparent counter electrode is opposed to the first surface of the active matrix substrate. The display device further includes a first circuit, a second circuit and a switching circuit. The first circuit supplies a voltage or a current to the transparent counter electrode for display purposes. The second circuit detects currents flowing from a number of points on the transparent counter electrode. And the switching circuit selectively connects electrically one of the first and second circuits to the transparent counter electrode.

  • Patent number: 6272814
    Abstract: A method of packaging a plurality of nut assemblies. Each nut assembly includes a flat head formed with a bolt hole, a pair of elongated flat arms extending parallel to each other in one direction from both sides of the head and each formed with a longitudinally elongated hole, and a nut substantially in the shape of a square pole having first and second opposed pairs of longitudinal sides and formed with pins protruding laterally through the first opposed pair of longitudinal sides and loosely received in the respective elongated holes of the arms so that the nut is pivotable about the pins relative to the arms. The nut is further formed with a threaded hole extending therethrough between the second opposed pair of longitudinal sides. To package such nut assemblies, a resilient package formed with elongated grooves having a width smaller than the distance between the second opposed pair of longitudinal sides of the nut is prepared, and a plurality of nut assemblies are pushed into the grooves of the package.

  • Patent number: 6099675
    Abstract: An adhesive tape is applied to an article covered with a resist pattern. The article with the adhesive tape applied thereto is rapidly cooled to form cracks in the resist pattern on the surface of the article to weaken the cohesion between the resist pattern and the surface of the article. After the cooling, the adhesive tape is separated from the article, whereby the resist pattern is removed with the adhesive tape from the surface of the article.

  • Patent number: 5891298
    Abstract: A method and apparatus for peeling protective adhesive tape 3 from work having the protective adhesive tape 3 applied to a surface of a semiconductor wafer W supported in a ring-shaped frame F by means of a supporting adhesive tape 1. Thin plates 4 with non-adhesive upper surfaces are applied to the supporting adhesive tape 1 adjacent a peel starting end 3a and a peel finishing end 3b of protective adhesive tape 3, respectively, to form regions for avoiding contact between a peeling tape 5 wound around an applying roller 8 and the like and the supporting adhesive tape 1. Subsequently, the peeling tape 5 is applied to the protective adhesive tape 3 at the peel starting end 3a with the applying roller 8, and a group of rollers 6-8 is moved horizontally on the work A to peel the peeling tape 5 and protective adhesive tape 3 together from the surface of semiconductor wafer W.
