  • Patent number: 8940374
    Abstract: A hybrid deposition process of CVD and ALD, called NanoLayer Deposition (NLD) is provided. The NLD process is a cyclic sequential deposition process, including introducing a first plurality of precursors to deposit a thin film and introducing a second plurality of precursors to modify the deposited thin film. The deposition using the first set of precursors is not self limiting and is a function of substrate temperature and process time. The second set of precursors modifies the already deposited film characteristics. The second set of precursors can treat the deposited film, including treatments such as modification of film composition and doping or removal of impurities from the deposited film. The second set of precursors can also deposit another layer on the deposited film. The additional layer can react with the existing layer to form a compound layer, or can have minimum reaction to form a nanolaminate film.

  • Publication number: 20120202353
    Abstract: A process to deposit a thin film by chemical vapor deposition includes evacuating a chamber of gases; exposing a device to a gaseous first reactant, wherein the first reactant deposits on the device to form the thin film having a plurality of monolayers in thickness; evacuating the chamber of gases; exposing the device, coated with the first reactant, to a gaseous second reactant under a plasma treatment, wherein the thin film is treated by the first reactant; and repeating the previous steps.

  • Publication number: 20120021138
    Abstract: A NanoLayer Deposition (NLD) process for depositing composite films of tertiary, quaternary, pentanary, and hexary stoichiometric films is provided. The inventive deposition process is a cyclic process consisting of a sequence of thin film deposition and treatment steps to obtain a desired film stoichiometry. The deposition steps are not self-limiting as in atomic layer deposition. In one embodiment for depositing a compound oxide film, the deposition process comprises a first deposition, followed by a hydrogen-containing plasma treatment, a second deposition followed by a hydrogen-containing plasma treatment, and then a third deposition followed by a hydrogen-containing plasma and then an oxygen-containing plasma treatment to produce a stoichiometric quaternary film. The cyclic process is repeated until the desired overall film thickness is achieved. The inventive process is used to fabricate high k dielectric films, ferroelectric films, piezoelectric films, and other complex oxides.

  • Patent number: 7425224
    Abstract: A high pressure trapping system is provided to collect chemical vapor by-products in successive stages through chemical reasons conducted at progressively colder temperatures. A hot trap receives chemical vapor exhaust and collects a first waste, typically a solid, as a result of the high temperature completing a chemical reason in the vapor. Surviving gaseous by-products continue to the next process. The following chamber is colder, and collects waste as a solid or a liquid as a result of a chemical process dependent on the cold temperature. Sometimes a third chamber is used for even a colder chemical reaction to collect waste products. As a solid, these waste products are easier to collect, remove, and even reuse.

  • Patent number: 7361387
    Abstract: A process system and a deposition method for depositing a highly controlled layered film on a workpiece is disclosed. The basic component of the apparatus is a pulsing plasma source that is capable of either exciting or not-exciting a first precursor. The pulsing plasma source includes an energy source to generate a plasma, and a plasma adjusting system to cause the plasma to either excite or not-excite a precursor. The precursor could flow continuously (an aspect totally new to ALD), or intermittently (or pulsing, standard ALD operation process). The deposition method includes the steps of pulsing the plasma to excite/not-excite the precursors and the ambient to deposit and modify the deposited layers. This procedure then can be repeated until the film reaches the desired thickness.
