Abstract: A method of etching exposed patterned heterogeneous structures is described and includes a remote plasma etch formed from a reactive precursor. The plasma power is pulsed rather than left on continuously. Plasma effluents from the remote plasma are flowed into a substrate processing region where the plasma effluents selectively remove one material faster than another. The etch selectivity results from the pulsing of the plasma power to the remote plasma region, which has been found to suppress the number of ionically-charged species that reach the substrate. The etch selectivity may also result from the presence of an ion suppression element positioned between a portion of the remote plasma and the substrate processing region.

Abstract: A method of conditioning internal surfaces of a plasma source includes flowing first source gases into a plasma generation cavity of the plasma source that is enclosed at least in part by the internal surfaces. Upon transmitting power into the plasma generation cavity, the first source gases ignite to form a first plasma, producing first plasma products, portions of which adhere to the internal surfaces. The method further includes flowing the first plasma products out of the plasma generation cavity toward a process chamber where a workpiece is processed by the first plasma products, flowing second source gases into the plasma generation cavity. Upon transmitting power into the plasma generation cavity, the second source gases ignite to form a second plasma, producing second plasma products that at least partially remove the portions of the first plasma products from the internal surfaces.

Abstract: Embodiments may include a method of etching. The method may also include flowing a gas mixture through a plasma discharge to form plasma effluents. The method may further include flowing the plasma effluents through a plurality of apertures to a layer on a substrate. The layer may have a first thickness. In addition, the method may include etching the layer with the plasma effluents. The method may also include measuring the intensity of emission from a reaction of plasma effluents with the layer. The method may further include summing the intensity of the emission while the plasma effluents are being flowed to the layer to obtain an integrated intensity. The method may then include comparing the integrated intensity to a reference value corresponding to a target etch thickness. The method may include extinguishing the plasma discharge when the integrated intensity is equal to or greater than the reference value.
