*100 mm and smaller are loaded on a carrier plate (150 mm)
*One 150 mm wafer - Loaded directly through the loadlock
*150 mm or 200 mm wafer don't need the carrier plate
*One 100 mm wafer - Loaded on a 150 mm carrier plate or dummy wafer with an etched recess through the load lock
*Up to 5 wafers when doing thermal ALD of oxides wafer size 100 mm, 150 mm and 200 mm
*Smaller samples - Loaded on a 150 mm carrier plate or dummy wafer with an etched recess through the load lock
*For deposition of thermal oxide up to five wafers can be loaded directly in the ALD chamber
