    摘要: A method for depositing a thin film on a substrate by plasma CVD includes: providing a vacuum chamber including a showerhead and a susceptor entirely facing the showerhead in parallel, placing a substrate on the susceptor entirely within the inner portion; and applying an RF power between the showerhead and the susceptor to deposit a thin film on the substrate. The susceptor includes an inner portion and a peripheral portion that is defined as any portion enclosing the inner portion and defines an electrically effective distance from the showerhead greater than that defined by the inner portion.
