Plasma cutting. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops ...
PECVD machine at LAAS technological facility in Toulouse, France. Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state (vapor) to a solid state on a substrate. Chemical reactions are involved in the process, which occur after creation of a plasma of the reacting gases.
Plasma modeling. Plasma modeling refers to solving equations of motion that describe the state of a plasma. It is generally coupled with Maxwell's equations for electromagnetic fields or Poisson's equation for electrostatic fields. There are several main types of plasma models: single particle, kinetic, fluid, hybrid kinetic/fluid, gyrokinetic ...
The plasma approximation: The plasma approximation applies when the plasma parameter Λ, [26] representing the number of charge carriers within the Debye sphere is much higher than unity. [ 19 ] [ 20 ] It can be readily shown that this criterion is equivalent to smallness of the ratio of the plasma electrostatic and thermal energy densities.
A plasma etcher, or etching tool, is a tool used in the production of semiconductor devices. A plasma etcher produces a plasma from a process gas, typically oxygen or a fluorine -bearing gas, using a high frequency electric field, typically 13.56 MHz. A silicon wafer is placed in the plasma etcher, and the air is evacuated from the process ...
List of plasma physicists. This is a list of physicists who have worked in or made notable contributions to the field of plasma physics . Name. Known for. Robert Ellis. Head of experimental projects at the Princeton Plasma Physics Laboratory; co-led the Spheromak project. Igor Grabec. Exploration of unstable ionization waves (striations) in a ...
Plasma processing is a plasma -based material processing technology that aims at modifying the chemical and physical properties of a surface. [1] Plasma processing techniques include: Related topics are plasma chemistry, chemical vapor deposition, and physical vapor deposition processes like sputter deposition, plasma iondoping, vacuum ...
Princeton Plasma Physics Laboratory (PPPL) is a United States Department of Energy national laboratory for plasma physics and nuclear fusion science. Its primary mission is research into and development of fusion as an energy source. It is known for the development of the stellarator and tokamak designs, along with numerous fundamental advances ...
