20140027054 | METHOD AND APPARATUS FOR BONDING WORKPIECES TOGETHER - Two workpieces composed of a resin workpiece and a resin workpiece, or composed of a resin workpiece and a glass substrate are bonded to each other such that troubles, such as an alignment shift and breakage etc. are not generated, while ensuring bonding uniformity. A first workpiece is placed on an inverting stage of an inverting stage unit, a second workpiece is placed on a work stage of a pressurizing stage unit, and UV light is radiated from a light irradiation unit. Then, the inverting stage is inverted 180°, the workpieces are overlapped each other on the work stage, and the workpieces are pressurized and pre-bonded to each other. Then, the workpieces in the pre-bonded state are transferred to a heating stage by a transfer means, the temperature of the workpieces is increased to a predetermined temperature by heating the workpieces, and the temperature is maintained until bonding is completed. | 01-30-2014 |
20140087199 | SURFACE TREATMENT METHOD FOR MOLDED ARTICLE, AND MOLDED ARTICLE PRODUCED FROM MATERIAL CONTAINING CYCLIC OLEFIN RESIN - A self-assembled monolayer is formed on the surface of a molded article without roughening the surface of the molded article to thereby perform treatment for preventing a biochemical substance from being adsorbed, for example, on a microchip substrate, and imparting functionality of immobilizing a biofunctional molecule thereto. The surface of a cyclic olefin resin molded article, for example, a microchip substrate, is irradiated with vacuum ultraviolet light having a center wavelength of 172 nm from an excimer lamp to activate a portion serving as a flow channel in the substrate. Next, the molded is immersed in a tank filled, for example, with a fluorine compound solution, and a SAM film that is a self-assembled monolayer is formed on the surface activated by ultraviolet radiation. | 03-27-2014 |
20140361196 | LIGHT SOURCE DEVICE, LIGHT IRRADIATING APPARATUS EQUIPPED WITH LIGHT SOURCE DEVICE, AND METHOD OF PATTERNING SELF-ASSEMBLED MONOLAYER USING LIGHT IRRADIATING APPARATUS - A light source device is disclosed that can be regarded as a point light source and that emits vacuum ultraviolet light at a sufficiently high optical intensity. The device has a lamp housing to house a flash lamp and a parabolic mirror. Light emitted from the flash lamp is converted to parallel light by the parabolic mirror, and the parallel light exits the lamp housing from a quartz window. The flash lamp has a pair of electrodes, and the distance between the electrodes is 12.5 mm or less. The filler gas pressure is between 2 atm and 8 atm. A current is fed to the flash lamp from an electricity feeding unit. This current requires 8 μs or less from the start of discharge until the current value reaches the peak value. The peak current value is 1500 A or more. The flash lamp emits light including vacuum ultraviolet light. | 12-11-2014 |
20150013388 | METHOD AND DEVICE FOR BONDING WORKPIECES EACH PRODUCED FROM GLASS SUBSTRATE OR QUARTZ SUBSTRATE - Vacuum ultraviolet light with a wavelength of 200 nm or less is applied on the joining surfaces of first and second workpieces made from a crystal substrate and a glass substrate, or a glass substrate and a glass substrate from a light irradiation unit. The workpieces are conveyed to a workpiece cleaning and laminating mechanism by a conveyance mechanism, the joining surfaces are subjected to mega-sonic cleaning as needed, and the workpieces are aligned with the joining surfaces thereof facing each other, and laminated such that the joining surfaces are in contact with each other. After being laminated, the laminated workpieces are conveyed to a workpiece heating mechanism and heated to increase the workpiece temperature to a predetermined temperature, and this temperature is maintained until joining is completed. The laminated workpieces are brought into a thermally expanded state upon heating, and are joined in this state. | 01-15-2015 |
