摘要： A method of etching silicon oxide from a narrow trench and a wide trench (or open area) is described which allows the etch in the wide trench to progress further than the etch in the narrow trench. The method includes two dry etch cycles. The first dry etch cycle involves a low intensity or abbreviated sublimation step which leaves solid residue in the narrow trench. The remaining solid residue inhibits etch progress in the narrow trench during the second dry etch cycle allowing the etch in the wide trench to overtake the etch in the narrow trench.

摘要： A method of etching silicon oxide from a multiple trenches is described which allows more homogeneous etch rates among trenches. The surfaces of the etched silicon oxide within the trench following the etch may also be smoother. The method includes two dry etch stages followed by a sublimation step. The first dry etch stage removes silicon oxide quickly and produces large solid residue granules. The second dry etch stage remove silicon oxide slowly and produces small solid residue granules in amongst the large solid residue granules. Both the small and large solid residue are removed in the ensuing sublimation step. There is no sublimation step between the two dry etch stages.

摘要： A method of etching a recess in a semiconductor substrate is described. The method may include forming a dielectric liner layer in a trench of the substrate where the liner layer has a first density. The method may also include depositing a second dielectric layer at least partially in the trench on the liner layer. The second dielectric layer may initially be flowable following the deposition, and have a second density that is less than the first density of the liner. The method may further include exposing the substrate to a dry etchant, where the etchant removes a portion of the first liner layer and the second dielectric layer to form a recess, where the dry etchant includes a fluorine-containing compound and molecular hydrogen, and where the etch rate ratio for removing the first dielectric liner layer to removing the second dielectric layer is about 1:1.2 to about 1:1.

摘要： A method of etching silicon-and-carbon-containing material is described and includes a SiConiTM etch in combination with a flow of reactive oxygen. The reactive oxygen may be introduced before the SiConiTM etch reducing the carbon content in the near surface region and allowing the SiConiTM etch to proceed more rapidly. Alternatively, reactive oxygen may be introduced during the SiConiTM etch further improving the effective etch rate.
