摘要： The invention can provide apparatus and methods of processing a substrate using plasma generation by gravity-induced gas-diffusion separation techniques. By adding or using gases including inert and process gases with different gravities (i.e., ratio between the molecular weight of a gaseous constituent and a reference molecular weight), a two-zone or multiple-zone plasma can be formed, in which one kind of gas can be highly constrained near a plasma generation region and another kind of gas can be largely separated from the aforementioned gas due to differential gravity induced diffusion and is constrained more closer to a wafer process region than the aforementioned gas.

The ion energy analyzer, used for determining an ion energy distribution of a plasma, includes a first grid and a second grid that is spaced away from and electrically isolated from the first grid. The first grid forms a first surface of the ion energy analyzer and is positioned to be exposed to the plasma. The first grid includes a first plurality of openings, which are dimensioned to be less than a Debye length for the plasma. A voltage source and an ion current meter are operably coupled to the second grid, the latter of which is configured to measure an ion flux onto the ion collector and to transmit a signal that represents the measured ion flux. The method includes selectively and variably biasing the second grid relative to the first grid.
