    摘要: An apparatus and a method for depositing materials, and more particularly a vapor deposition chamber configured to deposit a material during a plasma-enhanced process are provided. In one embodiment a chamber comprises a chamber body defining a process volume, a substrate support disposed in the process volume and configured to support one or more substrates, a process lid assembly disposed over the substrate support, wherein the process lid assembly has a plasma cavity configured to generate a plasma and provide one or more radical species to the process volume, a RF (radio frequency) power source coupled to the gas distribution assembly, a plasma forming gas source coupled with the process lid assembly, and a reactant gas source coupled with the process lid assembly.

    摘要: 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.
