What are Quartz Crystal Monitoring Systems aka QCM

The two type of quartz crystals used in film film thickness measurement are AT and RC types. The AT crystal is characterized through the molecular tetrahedral quartz crystal structure and single angle cut 35 or 15 units from the Zdirection which allows it to vibrate when a voltage is applied to it.
