Abstract: Implementations described herein generally relate to a method for forming a metal layer and to a method for forming an oxide layer on the metal layer. In one implementation, the metal layer is formed on a seed layer, and the seed layer helps the metal in the metal layer nucleate with small grain size without affecting the conductivity of the metal layer. The metal layer may be formed using plasma enhanced chemical vapor deposition (PECVD) and nitrogen gas may be flowed into the processing chamber along with the precursor gases. In another implementation, a barrier layer is formed on the metal layer in order to prevent the metal layer from being oxidized during subsequent oxide layer deposition process. In another implementation, the metal layer is treated prior to the deposition of the oxide layer in order to prevent the metal layer from being oxidized.

Abstract: Capacitor devices containing silicon boron nitride with high boron concentration are provided. In one or more examples, a capacitor device is provided and contains a stopper layer containing silicon boron nitride and disposed on a substrate, a dielectric layer disposed on the stopper layer, vias formed within the dielectric layer and the stopper layer, metal contacts disposed on bottoms of the vias, a nitride barrier layer containing a metal nitride material and disposed on walls of the vias and disposed on the metal contacts, and an oxide layer disposed within the vias on the nitride barrier layer, wherein the oxide layer contains one or more holes or voids formed therein. The silicon boron nitride contains about 18 atomic percent (at %) to about 50 at % of boron.

Abstract: Methods for forming the silicon boron nitride layer are provided. The method includes positioning a substrate on a pedestal in a process region within a process chamber, heating a pedestal retaining the substrate, and introducing a first flow of a first process gas and a second flow of a second process gas to the process region. The first flow of the first process gas contains silane, ammonia, helium, nitrogen, argon, and hydrogen. The second flow of the second process gas contains diborane and hydrogen. The method also includes forming a plasma concurrently with the first flow of the first process gas and the second flow of the second process gas to the process region and exposing the substrate to the first process gas, the second process gas, and the plasma to deposit the silicon boron nitride layer on the substrate.

Abstract: Embodiments of the disclosure generally relate to a method of processing a semiconductor substrate at a temperature less than 250 degrees Celsius. In one embodiment, the method includes loading the substrate with the deposited film into a pressure vessel, exposing the substrate to a processing gas comprising an oxidizer at a pressure greater than about 2 bars, and maintaining the pressure vessel at a temperature between a condensation point of the processing gas and about 250 degrees Celsius.
