Abstract: A method for forming a metal layer having a predetermined thickness on an underlying material is disclosed. According to the method, the underlying material is electroplated to form the metal layer having a fraction of the predetermined thickness thereon. The step of electroplating is interrupted for a predetermined period of time. The step of electroplating is then resumed to form the metal layer having the predetermined thickness on the underlying material, thereby improving planarity of the metal layer.

The method includes providing a substrate; providing a dielectric layer having trench openings and via openings on the substrate, wherein the ratio of the sum of the areas of the trench openings to the sum of the areas of the via openings is between 1 and 300; wherein the via opening bottom has a width of less than about 25 ?m; and electroplating a metal in the trench openings and via openings. An interconnect structure having at least one void-free via is further disclosed.

Abstract: Methods of forming, in an integrated circuit, aluminum-silicon contacts with a barrier layer is disclosed. The barrier layer is enhanced by the provision of titanium oxynitride layers adjacent the silicide film formed at the exposed silicon at the bottom of the contact. The titanium oxynitride may be formed by depositing a low density titanium nitride film over a titanium metal layer that is in contact with the silicon in the contact; subsequent exposure to air allows a relatively large amount of oxygen and nitrogen to enter the titanium nitride. A rapid thermal anneal (RTA) both causes silicidation at the contact location and also results in the oxygen and nitrogen being gettered to what was previously the titanium/titanium nitride interface, where the oxygen and nitrogen react with the titanium metal and nitrogen in the atmosphere to form titanium oxynitride. The low density titanium nitride also densifies during the RTA.

Abstract: A method for forming a dielectric layer within a microelectronics fabrication. There is first provided a substrate. There is then formed over the substrate a polysilicon resistor. There is then formed over the polysilicon resistor a first dielectric layer formed of a silicon nitride dielectric material deposited employing a plasma enhanced chemical vapor deposition (PECVD) method other than a high density plasma chemical vapor deposition (HDP-CVD) method. Finally, there is then formed over the first dielectric layer a second dielectric layer deposited employing a high density plasma chemical vapor deposition (HDP-CVD) method, where first dielectric layer attenuates a decrease in resistance of the polysilicon resistor incident to forming the second dielectric layer over the first dielectric layer.

Abstract: A method is provided for depositing aluminum thin film layers so as to form an improved metal contact in a semiconductor integrated circuit device. An initial layer of aluminum is deposited at a very low temperature, such as room temperature, to a depth sufficient to form a continuous layer. A second aluminum layer is then deposited at increasing temperatures and lower deposition rates in order to complete the deposition of the layer.
