DETERMINATION AND CONTROL OF TARGET THICKNESSES WITH QUARTZ CRYSTAL THICKNESS MONITOR

  • The measurement principle of model IL 100 thickness and rate monitor aredescribed. The method of converting linear thickness in nm units into mass thick-ness in μg/cm~2 units is mentioned. The effect of crucible temperature upon thick-ness determination is discussed. The gas amount absorbed by deposition foils isgiven.
