Coating an insulating film on a substrate, heating the substrate at a pressure higher than an atmospheric pressure in a chamber, followed by the curing process performed at a pressure lower than the atmospheric pressure in a separate chamber. The processes described herein can form a metal-rich metal chalcogenide, such as, for example, silver-rich silver selenide. The detection of slewing operations and the activation of current sources upon detection can be implemented using two comparator circuits\u2014one for a positive slewing operation, and one for a negative slewing operation. The rolled form is then welded into the formed shape to create the structural beam.
