    摘要: An iPVD system uses a high density inductively coupled plasma (ICP) at high pressure of at least 50 mTorr to deposit uniform ultra-thin layer of a tantalum nitride material barrier material onto the sidewalls of high aspect ratio nano-size features on semiconductor substrates, preferably less than 2 nm thick with less than 4 nm in the field areas. The process includes depositing an ultra-thin TaN barrier layer having a high nitrogen concentration that produces high resistivity, preferably at least 1000 micro-ohm-cm. The ultra-thin TaN film is deposited by a low deposition rate process of less than 20 nm/minute, preferably 2-10 nm/min, to produce the high N/Ta ratio layer without nitriding the tantalum target. The layer provides a barrier to copper (Cu) diffusion and a high etch resistant etch-stop layer for subsequent deposition-etch processes.

    摘要: A method and system for performing multiple depositions on a substrate using an improved Ionized Physical Vapor Deposition (IPVD) system that allows IPVD processes and plasma-enhanced processes, such as PEALD and PECVD, to be performed in a single processing chamber. A determination of the state of an in-coming substrate can be made by sensing the substrate automatically or interrogating data relating to the state of the substrate to arrive at the determination. A controller selects and executes a process in response to the determination using a processing apparatus configured to alternatively perform multiple processes in response to commands from the controller.

    摘要: An iPVD apparatus (20) is programmed to deposit material (10) into high aspect ratio submicron features (11) on semiconductor substrates (21) by cycling between deposition and etch modes within a vacuum chamber (30). The modes operate at different power and pressure parameters. Pressure of more than 50 mTorr, for example, is used for sputtering material from a target while pressure of less than a few mTorr, for example, is used to etch. Bias power on the substrate is an order of magnitude higher for etching, producing several hundred volt bias for etching, but only a few tens of volts for deposition. The alternating etching modes remove deposited material that overhangs edges of features on the substrate, removes some of the deposited material from the bottoms (15) of the features, and resputters the removed deposited material onto sidewalls (16) of the features. The substrate (21) is cooled during deposition and etching, and particularly during etching to substantially below 0° C. RF energy is coupled into the chamber (30) to form a high density plasma, with substantially higher RF power coupled during deposition than during etching. The substrate (21) is moved closer to the plasma source during etching than during deposition.

    摘要: An iPVD apparatus (20) is programmed to deposit material (10) onto semiconductor substrates (21) by cycling between deposition and etch modes within a vacuum chamber (30). Static magnetic fields are kept to a minimum during at least the etch modes, at least less than 150 Gauss, typically less than 50 Gauss, and preferably in the range of 0-10 Gauss. Static magnetic fields during deposition modes may be more than 150 Gauss, in the range of 0-50 Gauss, or preferably 20-30 Gauss, and may be the same as during etch modes or switched between a higher level during deposition modes and a lower level, including zero, during etch modes. Such switching may be by switching electromagnet current or by moving permanent magnets, by translation or rotation. Static magnetic fields are kept to a minimum during at least the etch modes, at least less than 150 Gauss, typically less than 50 Gauss, and preferably in the range of 1-10 Gauss. The modes may operate at different power and pressure parameters. Pressure of more than 50 mTorr are preferred for deposition in a thermalized plasma while pressure of less than a few mTorr is preferred for etching.
