摘要： A method of forming a contact in an integrated circuit between a first metalization layer and a silicon substrate. In one embodiment the method comprises forming a premetal dielectric layer over the silicon substrate, etching a contact hole through the premetal dielectric layer and then forming a thin silicon nitride layer on an outer surface of the contact hole. The silicon nitride layer reduces overetching that may otherwise occur when oxidation build-up is removed from the silicon interface within the contact hole by a preclean process. After the preclean process, the contact hole is then filled with one or more conductive materials. In various embodiments the silicon nitride layer is formed by exposing the contact hole to a nitrogen plasma, depositing the layer by a chemical vapor deposition process and depositing the layer by an atomic layer deposition process. In other embodiments, the method is applicable to the formation of vias through intermetal dielectric layers.

摘要： A method for forming a refractory metal layer that features two-stage nucleation prior to bulk deposition of the same. The method includes placing a substrate in a deposition zone, flowing, into the deposition zone during a first deposition stage, a silicon source, such as a silane gas, and a tungsten source, such as tungsten-hexafluoride gas, so as to obtain a predetermined ratio of the two gases therein. During a second deposition stage, subsequent to the first deposition stage, the ratio of the two gases is varied. Specifically, in the first deposition stage there is a greater quantity of silane gas than tungsten-hexafluoride gas. In the second deposition stage there may be a greater quantity of tungsten-hexafluoride than silane.

摘要： An apparatus and process for limiting residue remaining after the etching of metal in a semiconductor manufacturing process by injecting a halogen-containing gas without a plasma into a processing chamber. The wafer is then exposed to the remnants of the halogen-containing gas in the chamber before the metal is deposited on the wafer. The exposure can occur in the same chamber as the metal deposition, or a different chamber. The wafer can remain in the chamber or be moved to another chamber for etching after exposure and deposition.

摘要： A layer of tungsten nitride is deposited on the upper surface of a wafer. The deposition is performed by providing a gaseous mixture and providing energy to the gaseous mixture to form a plasma. The gaseous mixture includes a first gaseous composition containing tungsten and a second gaseous composition containing nitrogen and hydrogen. The second gaseous composition is one that does not have a gas phase reaction with the first gaseous composition to form tungsten nitride, unless energy is provided to the gaseous mixture. The first gaseous composition may be tungsten hexafluoride (WF6). The gaseous mixture may be infused with energy to form a plasma by providing it with energy from an rf signal. In the plasma, the nitrogen dissociates into nitrogen ions, and the tungsten separates from the fluorine. The nitrogen ions and tungsten then combine to form tungsten nitride (W2N), which deposits on the wafer's upper surface.
