Abstract: A method produces adhesive tapes which are adhesive at least on one side, wherein an adhesive tape web, in which the at least one adhesive side is covered by a first liner, is guided into a cutting device in which a total of N individual adhesive tape strips located next to one another are produced in the machine direction from the adhesive tape web. Every other adhesive tape strip is removed from the first liner and is applied to a second liner in each case having a spacing a between the individual adhesive tape strips. The liners are cut between the adhesive tape strips located on the first liner and on the second liner, and the individual adhesive tapes, together with the liner strips, are wound up in a total of X rolls in a form of an Archimedean spiral.

Abstract: A process for production of a crosswound long roll of an at least single-side-adhesive adhesive tape in which at least one adhesive side of the adhesive tape has been covered with a liner, in the form of an Archimedean spiral. The process releasably fixes a core on an axle, wherein the adhesive tape covered with the liner is wound on to the core, contacts a pressure roll with a curved surface of the core or with the adhesive tape which has been covered with the liner and already wound on the core, in such a way as to give a nip between pressure roll and curved surface of the core or adhesive tape covered with the liner, where core and pressure roll rotate in opposite directions. Further, the process unwinding the liner from a liner roll, places the liner on to the at least one open adhesive side of the adhesive tape which is guided on the pressure roll in the direction of the nip, and guides a laminate made of adhesive tape and liner on the pressure roll into the nip.

Abstract: An apparatus and a method for semiconductor wafer bonding provide in-situ and real time monitoring of semiconductor wafer bonding time. Deflection of the wafer edges during the last phase of the direct bonding process indicates the end of the bonding process. The apparatus utilizes a distance sensor to measure the deflection of the wafer edges and the bonding time is measured as the time between applying the force (bonding initiation) and completion of the bonding process. The bonding time is used as a real-time quality control parameter for the wafer bonding process.

Abstract: An injection-moulding tool for the production of a mould in disc form, in particular in the form of information carriers such as CDs and/or DVDs, wherein the injection-moulding tool comprises a first and a second mirror block, wherein the first and second mirror blocks lie opposite each other and are movable in relation to each other for the opening and closing of the mould, and means for actively controlling the temperature of at least one of the first and second mirror blocks. A method for producing mouldings in disc form utilizing the injection-moulding tool is also disclosed.

Abstract: An injection molding tool is described for the production of disc-like information carriers, in particular in the form of CD's and/or DVD's. The injection molding tool has a first and a second mirror block which form the cavity and which are located opposite to each other and which, for allowing an opening and a closure of the cavity, are movable relative to each other. In addition to that it has a form ring which encloses the first mirror block concentrically, and which borders the cavity towards its outer edge, and which is movable relative to the first mirror block, wherein between the first mirror block and the form ring enclosing it a sliding ring is provided for the reduction of friction if the form ring moves relative to the first mirror block.

Abstract: The invention relates to a method and to a device for cleaning and then bonding substrates. According to the invention, at least two opposite substrates are obliquely or vertically sprayed with a cleansing liquid by means of at least one nozzle and are preferably dried, aligned and directly bonded under micro-clean room conditions. The bonding process is preferably visually monitored during bonding in order to immediately remove insufficiently bonded substrates from the process. The inventive device is compact and allows integration of the process steps in a single installation without disruption. The invention is further characterized by an improved quality of the bonded layers and an improved productivity of the bonding process. It also allows the use of novel bonding processes.

Abstract: The present invention provides a process and a device for treating the surfaces or bonding surfaces of substrates before bonding the substrates. In accordance with the invention, the surfaces of substrates to be bonded are treated with an atmospheric plasma before bonding. The surfaces of the substrates can thus be cleaned, chemically activated or removed. However, it is also possible to grow a layer by corresponding reactive plasma gases. The invention is advantageous in that bonded substrates can be produced in a simple and cost-saving manner, wherein a high adhesive strength can be achieved.

Abstract: A method and a device for the post-processing of a disc-shaped information- and/or structure carrier for injection molding forms is described, for example for a stamper for the production of CDs or DVDs, which has a central, substantially cylindrical opening. The information- and/or structure carrier is held in the injection molding form through a holding device penetrating the opening at least partially, for example a ring-shaped stamper holder. The information- and/or structure, respectively, is provided substantially concentrically to this opening on a surface facing the cavity of the injection molding form.
