Latest Patents
One of Tsujimura's notable inventions is a device and method for joining substrates, designed to operate within a clean booth. This innovative system utilizes both a single axis robot and a five axis robot to handle and convey wafers and glass substrates. The process begins at a transcribing station where adhesive is applied to a transcribing film from a film supplying section. This film is then pressed onto the glass substrate to allow for the transfer of adhesive. A peeling station follows to remove the film from the glass substrate. At the joining station, the wafer and glass substrate are precisely positioned, with parallelism adjustments made to join the surfaces effectively. This method greatly mitigates the risks of contamination, enhancing the yield ratio of the final products.
