An alignment target includes periodic patterns on two elements. The casting element is able to make contact with an upstream element of the installation and comprises means for controlling the angular orientation of the tube about its axis with respect to the upstream element, these means being capable of giving the tube at least three distinct orientations. A sealing member is configured to sealingly close the container opening. According yet to another embodiment, the nearest ideal sample value is selected based on the received sample value and a value of a previous sample. The streaming and resource sharing optimizers may also configure portions of the modified model to execute at a faster rate. Using the resist as a mask, the silicon nitride film is selectively etched away.
