  • Patent number: 10217616
    Abstract: A method of controlling a temperature is provided. In the method, a plasma process is performed in a processing chamber on an object to be processed placed on an electrostatic chuck configured to have its temperature adjustable.

  • Patent number: 10192717
    Abstract: Embodiments of the present disclosure generally relate to methods for conditioning an interior wall surface of a remote plasma generator. In one embodiment, a method for processing a substrate is provided. The method includes exposing an interior wall surface of a remote plasma source to a conditioning gas that is in excited state to passivate the interior wall surface of the remote plasma source, wherein the remote plasma source is coupled through a conduit to a processing chamber in which a substrate is disposed, and the conditioning gas comprises an oxygen-containing gas, a nitrogen-containing gas, or a combination thereof. The method has been observed to be able to improve dissociation/recombination rate and plasma coupling efficiency in the processing chamber, and therefore provides repeatable and stable plasma source performance from wafer to wafer.

  • Patent number: 10144041
    Abstract: Use of supercritical CO2 for cleaning long, narrow pipes with a cross sectional area of less than 1000 square mm and a length of more than 500 meter. Cleaning is performed by adding a fluid to the lumen of the pipe (140); providing the fluid (2) in a supercritical state (6) inside the lumen; and subsequently, as a flushing step, while the fluid is in the supercritical state or in a liquid state, displacing the fluid (2) in the lumen of the pipe (140) and out of lumen of the pipe at a speed that causes a turbulent flow of the fluid, thereby flushing particles out of the lumen.

  • Patent number: 10147618
    Abstract: A time-dependent substrate temperature to be applied during a plasma process is determined. The time-dependent substrate temperature at any given time is determined based on control of a sticking coefficient of a plasma constituent at the given time. A time-dependent temperature differential between an upper plasma boundary and a substrate to be applied during the plasma process is also determined. The time-dependent temperature differential at any given time is determined based on control of a flux of the plasma constituent directed toward the substrate at the given time. The time-dependent substrate temperature and time-dependent temperature differential are stored in a digital format suitable for use by a temperature control device defined and connected to direct temperature control of the upper plasma boundary and the substrate. A system is also provided for implementing upper plasma boundary and substrate temperature control during the plasma process.

  • Patent number: 9704951
    Abstract: A magnetic field-guided method of metal-assisted chemical etching comprises immersing a structure that comprises a two-dimensional magnetic pattern layer on a surface thereof in an etchant solution. The magnetic pattern layer sinks into the structure as portions of the structure directly under the magnetic pattern layer are etched. A programmable magnetic field H(t) is applied to the structure during etching to guide the sinking of the magnetic pattern layer, thereby controlling the etching of the structure in three dimensions.

  • Patent number: 9687891
    Abstract: A system and method for pipe cleaning are disclosed, which include arranging at least one pump to draw a flow of water from the body of water. An output of the at least one pump is fluidly connected to the pipe through a junction disposed between the one end of the pipe and the free end of the pipe, and the at least one pump is activated to draw the flow of water and provide the flow of water to the pipe through the junction such that a flow of water passes through the pipe to remove the debris. The debris is thus entrained in the flow of water and ejected from the pipe through the free end into the body of water until the pipe is clean.
