Patent number: 9896605Abstract: The invention describes a double-sided, carrierless self-adhesive tape which can be used in particular for achieving very durable adhesive bonding of a variety of articles. This double-sided, carrierless self-adhesive tape is composed of a homogeneously crosslinked pressure-sensitive acrylate hotmelt composition of single-layer construction, which may have been lined with release materials such as siliconized release papers or release films. The double-sided, carrierless pressure-sensitive adhesive tape is characterized in that it is composed of a photoinitiator-free, thermally homogeneously crosslinked acrylate hotmelt which is crosslinked predominantly by way of urethane units. It is notable in particular for the fact that it is homogeneously chemically crosslinked through the layer and, in contrast to acrylate layers crosslinked by radiation (UV/EBC), does not exhibit any profile of crosslinking through the layer.Type: GrantFiled: September 23, 2014Date of Patent: February 20, 2018Assignee: TESA SEInventors: Stephan Zöllner, Sven Hansen, Kay Brandes, Jorg Speer

Patent number: 9824909Abstract: A chuck for aligning a first planar substrate in parallel to a second planar substrate includes a top plate having a top surface for arrangement of the first planar substrate. A bottom plate is at least one distance measuring sensor configured to measure a distance between the top surface of the top plate and a surface of the second planar substrate, and at least three linear actuators in contact with the top plate and the bottom plate. The method for setting a gap between the first and second planar substrate includes measuring the thickness of the first planar substrate and measuring between a surface of the second planar substrate and the top surface of the top plate. The tilt adjusts between a top surface of the first planar substrate or the chuck and the surface of the second planar substrate by using at least three linear actuators of the chuck.Type: GrantFiled: December 4, 2013Date of Patent: November 21, 2017Assignee: SUSS MICROTEC LITHOGRAPHY GMBHInventors: Sven Hansen, Thomas Huelsmann, Katrin Schindler

Patent number: 9329473Abstract: The invention relates to a method and device for expanding the travel or control displacement of linear actuators that is available during an imprinting or embossing stroke. The wedge error compensating head (2) comprises a movable part (4), a stationary part (3) and at least three linear actuators (8). Each linear actuator (8) is connected to one of the parts (3, 4) at one end and to the other of the two parts (4, 3) by wedges (9) at the other end. By means of the wedges (9), it is possible to coarsely or roughly compensate for wedge errors and possible tolerances of individual subcomponents of the system. The linear actuators (8) are only used for fine or precision compensation for the wedge error. In this way, sufficient control displacement is available for the imprinting stroke with the linear actuators.Type: GrantFiled: February 14, 2011Date of Patent: May 3, 2016Assignee: SUSS MICROTEC LITHOGRAPHY GMBHInventors: Sven Hansen, Matthias Conradi, Georg Fink
