  • Publication number: 20110086501
    Abstract: A method of processing a substrate having horizontal and non-horizontal surfaces is disclosed. The substrate is implanted with particles using an ion implanter. During the ion implant, due to the nature of the implant process, a film may be deposited on the surfaces, wherein the thickness of this film is thicker on the horizontal surfaces. The presences of this film may adversely alter the properties of the substrate. To rectify this, a second process step is performed to remove the film deposited on the horizontal surfaces. In some embodiments, an etching process is used to remove this film. In some embodiments, a material modifying step is used to change the composition of the material comprising the film. This material modifying step may be instead of, or in addition to the etching process.

  • Publication number: 20110039034
    Abstract: A method of depositing and crystallizing materials on a substrate is disclosed. In a particular embodiment, the method may include creating a plasma having deposition-related species and energy-carrying species. During a first time period, no bias voltage is applied to the substrate, and species are deposited on the substrate via plasma deposition. During a second time period, a voltage is applied to the substrate, which attracts ions to and into the deposited species, thereby causing the deposited layer to crystallize. This process can be repeated until an adequate thickness is achieved. In another embodiment, the bias voltage or bias pulse duration can be varied to change the amount of crystallization that occurs. In another embodiment, a dopant may be used to dope the deposited layers.

  • Publication number: 20110000896
    Abstract: A method is disclosed for adjusting the composition of plasmas used in plasma doping, plasma deposition and plasma etching techniques. The disclosed method enables the plasma composition to be controlled by modifying the energy distribution of the electrons present in the plasma. Energetic electrons are produced in the plasma by accelerating electrons in the plasma using very fast voltage pulses. The pulses are long enough to influence the electrons, but too fast to affect the ions significantly. Collisions between the energetic electrons and the constituents of the plasma result in changes in the plasma composition. The plasma composition can then be optimized to meet the requirements of the specific process being used. This can entail changing the ratio of ion species in the plasma, changing the ratio of ionization to dissociation, or changing the excited state population of the plasma.

  • Publication number: 20100273322
    Abstract: A technique for conformal processing of a substrate having a non-planar surface is disclosed. The technique includes several stages. In a first stage, some surfaces of the substrate are effectively processed. During a second stage, these surfaces are treated to limit or eliminate further processing of these surfaces. During a third stage, other surfaces of the substrate are processed. In some applications, the surfaces that are perpendicular, or substantially perpendicular to the flow of particles are processed in the first and second stages, while other surfaces are processed in the third stage. In some embodiments, the second stage includes the deposition of a film on the substrate.

  • Patent number: 7820533
    Abstract: A method of multi-step plasma doping a substrate includes igniting a plasma from a process gas. A first plasma condition is established for performing a first plasma doping step. The substrate is biased so that ions in the plasma having the first plasma condition impact a surface of the substrate thereby exposing the substrate to a first dose. The first plasma condition transitions to a second plasma condition. The substrate is biased so that ions in the plasma having the second plasma condition impact the surface of the substrate thereby exposing the substrate to a second dose. The first and second plasma conditions are chosen so that the first and second doses combine to achieve a predetermined distribution of dose across at least a portion of the substrate.

  • Patent number: 7822805
    Abstract: A system and method for screening a potential customer and assigning an account number to the potential customer prior to permitting the potential customer to purchase products or services from an automated seller facility over a computer network, such as the Internet, is disclosed. The potential customer enters customer data into a user interface to be received by the seller in the automated seller facility so that the seller can check the potential customer's qualifications. The invention includes performing an initial screening to determine whether the potential customer is qualified to purchase the products or services from the seller. If the potential customer passes the initial screening, an account number is issued to the potential customer. The account number allows the potential customer further access to the automated seller facility so that the potential customer may make an offer to purchase products or services while the automated seller facility performs a complete screening.

  • Publication number: 20100252531
    Abstract: A plasma processing tool is used to deposit material on a workpiece. For example, a method for conformal deposition of material is disclosed. In this embodiment, the plasma sheath shape is modified to allow material to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of different features can be deposited onto. In another embodiment, a plasma processing tool is used to etch a workpiece. In this embodiment, the plasma sheath shape is altered to allow ions to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of differently shaped features can be created.

  • Publication number: 20100155898
    Abstract: A method is disclosed for enhancing tensile stress in the channel region of a semiconductor structure. The method includes performing a series of ion implantation steps at predetermined implant energies to implant carbon ions deep within the semiconductor structure to create a strain layer. The strain layer is annealed using a millisecond anneal process. Subsequent ion implantation steps are used to dope the source/drain region, and the source/drain extension with phosphorus ions, so that the doped regions remain above the strain layer. A second millisecond anneal step activates the source/drain region and the source/drain extension. The strain layer enhances carrier mobility within a channel region of the semiconductor structure, while also preventing diffusion of P within the structure.
