Abstract:
Methods and apparatus provide for imparting a controlled supply of gas to at least one Bernoulli chuck to provide a balanced draw and repellant gas flow to a material sheet; and at least one of: elevating a temperature of the supply of gas to the at least one Bernoulli chuck such that the gas flow to the material sheet is provided at the elevated temperature, providing a stream of gas to an insulator substrate to promote separation of an exfoliation layer from a donor semiconductor wafer, and providing a stream of gas to a junction of the insulator substrate and any support structure to promote separation of the insulator substrate and the supporting structure.
Abstract:
An incorrect label removal system is disclosed for removing unwanted labels from a web of labels in a labeling machine. The incorrect label removal system includes a label peel assembly positioned between two fixed points along the direction of travel of the web of labels. The label peel assembly provides a first orientation in which labels remain on the web as the web passes the label peel assembly, and selectively provides a second orientation in which labels are removed from the web. The label peel assembly provides that a length of the web between the two fixed points is substantially the same when the label peel assembly is in each of the first orientation and the second orientation.
Abstract:
While a vicinity of a bottom surface-side region of a pressure-sensitive adhesive sheet (3) corresponding to an adhesion region (R1) of a semiconductor chip (1) are sucked and held, a plurality of protruding portions (30) of a removing member (21) are brought into contact with the bottom surface of the semiconductor chip through the adhesive sheet at the region. Also, the adhesive sheet is sucked in between the respective protruding portions so as to change a surface bonding of the semiconductor chip to the adhesive sheet by adhesion to a point bonding, and further the removing member is moved along the bottom surface of the semiconductor chip so as to change a position of the point bonding and decrease bonding force to the adhesive sheet by the adhesion. Then, the semiconductor chip is removed from the adhesive sheet.
Abstract:
In an adhesive sheet exfoliation process in a pick-up operation fora thin-type chip 6 adhered to the adhesive sheet 5, a suction exfoliation tool 22 provided at its adhesion surface 22a with plural suction grooves 22b is abutted against the lower surface of the adhesive sheet 5. Then, air within the suction grooves 22b are vacuum-sucked to bend and deform the adhesive sheet 5 together with he chip 6 thereby to exfoliate the adhesive sheet 5 from the lower surface of the chip 6 due to such bending deformation. Thus, it is possible to realize the picking-up operation with high productivity without causing a problem such as breakage or crack.
Abstract:
An apparatus for exchanging a first gas contained in a sealed container (12) for a second gas. The apparatus comprises a vacuum chamber (14) for receiving the container (12) and for maintaining a controlled pressure about the container, a gas exchange head (50) for exchanging gas in the container while maintaining a seal between the container and the chamber, and a vacuum source (22) coupled to the gas exchange head (50) and to the vacuum chamber (14) for evacuating the first gas from the container (12) and air from the chamber. The apparatus further has a gas source (24) for supplying the second gas, the gas source being coupled to the gas exchange head (50) for supplying the second gas to the container (12), and a sensor (53) for monitoring the pressure in the container during gas exchange. The present invention further provides for a controller for adjusting the rate with which the first gas is removed from the container (12) and the rate at which the chamber is evacuated such that the container is not damaged, and the controller can adjust the rate at which gas is supplied to the container and the rate with which the chamber is pressurized so as not to damage said container.
Abstract:
Die vorliegende Erfindung betrifft eine Vorrichtung zum Lösen eines ersten Substrats (8) von einem zweiten Substrat (6) in einer Löserichtung (L) mit: - mindestens zwei quer zur Löserichtung (L) und in einer Radialrichtung (R) zum ersten Substrat (8) geführte Klemmelemente (1, 1', 1'', 1'") zur Klemmung des ersten Substrats (8) quer zur Löserichtung (L), - einer Substrathalterung (11, 11 ') zur Halterung des zweiten Substrats (6) und - Lösemittel zum Lösen des ersten Substrats (8) vom zweiten Substrat (6) durch Bewegung des durch die Klemmelemente (1, 1', 1'', 1'") fixierten ersten Substrats (8) in der Löserichtung (L) und/oder durch Bewegung der Substrathalterung (11, 11') entgegen der Löserichtung (L). Weiterhin betrifft die vorliegende Erfindung ein korrespondierendes Verfahren.
