    Abstract: Embodiments of the present invention generally relates to an apparatus and a method for processing semiconductor substrates. Particularly, embodiments of the present invention relates to methods and apparatus for trench and via profile modification prior to filling the trench and via. One embodiment of the present invention comprises forming a sacrifice layer to pinch off a top opening of a trench structure by exposing the trench structure to an etchant. In one embodiment, the etchant is configured to remove the first material by reacting with the first material and generating a by-product, which forms the sacrifice layer.

    Abstract: Embodiments of the present invention generally relates to an apparatus and a method for processing semiconductor substrates. Particularly, embodiments of the present invention relates to apparatus and methods for forming shallow trench isolations having recesses with rounded bottoms. One embodiment of the present invention comprises forming a recess in a filled trench structure by removing a portion of a material from the filled trench structure and rounding bottom corners of the recess. Rounding bottom corners is performed by depositing a conformal layer of the same material filled in the trench structure over the substrate and removing the conformal layer of the material from sidewalls of the recess.

    Abstract: Methods for etching dielectric layers comprising silicon and nitrogen are provided herein. In some embodiments, such methods may include providing a substrate having a dielectric layer comprising silicon and nitrogen disposed thereon, forming reactive species from a process gas comprising hydrogen (H2) and nitrogen trifluoride (NF3) using a remote plasma; and etching the dielectric layer using the reactive species. In some embodiments, an oxide layer is disposed adjacent to the dielectric layer. In some embodiments, the flow rate ratio of the process gas can be adjusted such that an etch selectivity of the dielectric layer to at least one of the oxide layer or the substrate is between about 0.8 to about 4.
