Test Specifications

During a process design and qualification period, samples from each deposition run are subjected to a set of tests. Some of these are to ensure good adhesion to the substrate material, sometimes at elevated temperatures for die bonding purposes, sometimes at subzero temperatures to ensure continuous operation; other tests establish tribology standard, spectral shift, etc.
