Abstract:
A processing method of processing a substrate is presented that includes: receiving pre-process data, wherein the pre-process data comprises a desired process result and actual measured data for the substrate; determining a required process result, wherein the required process result comprises the difference between the desired process result and the actual measured data; creating a new process recipe by modifying a nominal recipe obtained from a processing tool using at least one of a static recipe and a formula model, wherein the new process recipe provides a new process result that is approximately equal to the required process result; and sending the new process recipe to the processing tool and the substrate.
Abstract:
A method of creating a virtual profile library includes obtaining a reference signal. The reference signal was generated by measuring a signal off a reference structure on a semiconductor wafer with a metrology device. The reference signal is compared to a plurality of signals in a first library. The comparison is stopped if a first matching criteria is met. The reference signal is compared to a plurality of signals in a second library. The comparison is stopped if a second matching criteria is met. A virtual profile data space is created when the first and second matching criteria are not met. The virtual profile data space is created using differences between a profile data space associated with the first library and a profile data space associated with the second library. A first virtual profile signal is created in the virtual profile data space. A virtual profile shape and/or virtual profile parameters is created based on the first virtual profile signal. A difference is calculated between the reference signal and the first virtual profile signal. The difference is compared to a virtual profile library creation criteria. If the virtual profile library creation criteria is met, the first virtual profile signal and the virtual profile data, which includes the virtual profile shape and/or virtual profile parameters, associated with the first virtual profile signal is stored. Or, if the virtual profile library creation criteria is not met, a corrective action is applied.

Abstract:
A process by which an ion energy analyzer is manufactured includes processing a first substrate to form an entrance grid having a first channel and a first plurality of openings extending therethrough. A second substrate is processed to form a selection grid having a second channel therein and a second plurality of openings extending therethrough. A third substrate is processed to form an ion collector having a third channel therein. The entrance grid is operably coupled to, and electrically isolated from, the selection grid, which is, in turn, operably coupled to, and electrically isolated from, the ion collector.

A plasma processing system. The processing system comprises a process chamber having first and second ends arranged such that the first end opposes the second end. A substrate support is positioned at the first end of the process chamber and is configured to support a substrate. An exhaust system is positioned proximate the second end of the process chamber and draws a vacuum on the process chamber. Between the exhaust system and substrate support there is a plurality of super-Debye openings, and between the exhaust system and the plurality of super-Debye openings is a plurality of sub-Debye openings. The super-Debye openings are configured to limit diffusion of plasma while the sub-Debye openings are configured to quench plasma.
Abstract:
A surface wave plasma (SWP) source is described. The SWP source comprises an electromagnetic (EM) wave launcher configured to couple EM energy in a desired EM wave mode to a plasma by generating a surface wave on a plasma surface of the EM wave launcher adjacent the plasma. The EM wave launcher comprises a slot antenna having a plurality of slots. The SWP source further comprises a first recess configuration formed in the plasma surface, wherein the first recess configuration is substantially aligned with a first arrangement of slots in the plurality of slots, and a second recess configuration formed in the plasma surface, wherein the second recess configuration is either partly aligned with a second arrangement of slots in the plurality of slots or not aligned with the second arrangement of slots in the plurality of slots. A power coupling system is coupled to the EM wave launcher and configured to provide the EM energy to the EM wave launcher for forming the plasma.
Abstract:
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.
Abstract:
A method of generating a signal representing with an ion energy analyzer for use in determining an ion energy distribution of a plasma. 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.
