The entrance grid includes a first plurality of openings dimensioned to be less than a Debye length for the plasma. The ion collector is coupled to the entrance grid via a first voltage source. The selection grid is positioned between the entrance grid and the ion collector and is coupled to the entrance grid via a second voltage source. An ion current meter is coupled to the ion collector to measure an ion flux onto the ion collector and transmit a signal related thereto.

摘要： 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.

摘要： Embodiments of the present invention relate to the analysis of the components of one or more gases, for example a gas mixture sampled from a semiconductor manufacturing process such as plasma etching or plasma enhanced chemical vapor deposition (PECVD). Particular embodiments provide sufficient power to a plasma of the sample, to dissociate a large number of the molecules and molecular fragments into individual atoms. With sufficient power (typically a power density of between 3-40 W/cm3) delivered into the plasma, most of the emission peaks result from emission of individual atoms, thereby creating spectra conducive to simplifying the identification of the chemical composition of the gases under investigation. Such accurate identification of components of the gas may allow for the precise determination of the stage of the process being performed, and in particular for detection of process endpoint.

摘要： A method for controlling the plasma etching of semiconductor wafers determines the impedance of a plasma chamber using values representing voltage, current, and the phase angle between them, as provided by a sensor. All or less than all of the data during a first time period may be used to calculate a model. During a second time period, real time data is used to calculate a version of the instant impedance of the chamber. This version of impendence is compared to a time-projected version of the model. The method determines that etching should be stopped when the received data deviates from the extrapolated model by a certain amount. In some embodiments a rolling average is used in the second time period, the rolling average compared to the model to determine the end point condition.
