Weboscillating quartz monitor using a single quartz crystal, with two pairs of gold electrodes deposited on it. The possibility of using this arrangement was investigated by Van Empel et al (1971a, b). However, several commercial quartz crystal thickness monitors (Fox and Katz 1969) are also available in which two quartz crystals are used. WebSPECIFICATIONS. SungThai offers both 5 MHz and 6 MHz AT-cut quartz thickness-monitor crystals. These products are offered with gold, silver, and alloy coated electrodes for major optical and vacuum coating applications, PVD, and for use in thin film deposition processes. Silver-aluminum alloy quartz monitor crystalsl is coated with optical film.

WebFrom time to time, we have encountered that some film thickness monitors are unable to properly maintain the resonance frequency the HT and RC Crystals require. As a result, these crystals will appear as “dead” or 0% health on the monitor status screen. This phenomenon can also be termed ‘mode skipping’ and is the result of a remote ...
