| 摘要 |
A process system and a deposition method for depositing a highly controlled layered film on a workpiece is disclosed. The basic component of the present invention apparatus is a pulsing plasma source capable of either exciting or not-exciting a first precursor. The pulsing plasma source includes an energy source to generate a plasma, and a plasma adjusting system to cause the plasma to either excite or not-excite a precursor. The precursor could flow continuously (an aspect totally new to ALD), or intermittently (or pulsing, standard ALD operation process). The present invention further provides a method to deposit highly controlled layered film on a workpiece. The method comprises the steps of pulsing the plasma to excite/not-excite the precursors and the ambient to deposit and modify the depositing layers. This procedure then can be repeated alternately until the film reaches a desired thickness. |
