Should depend on #4 but we're having issues with the dependencies dropdown.

Instead of depending on #4 directly, please create (an) intermediate Process element which details what the Wet Lab is going to be used for in this application. You can group everything into one element, if the processes are not wildly unrelated.

This will also need #57 (Metal Thin Film Deposition), right? Or more concretely, it specifically requires #37 (Sputtering)?
