摘要:
A method for processing substrate in a processing chamber, which has at least one plasma generating source and a gas source for providing process gas into the chamber, is provided. The method includes exciting the plasma generating source with an RF signal having RF frequency. The method further includes pulsing the gas source, using at least a first gas pulsing frequency, such that a first process gas is flowed into the chamber during a first portion of a gas pulsing period and a second process gas is flowed into the chamber during a second portion of the gas pulsing period, which is associated with the first gas pulsing frequency. The second process gas has a lower reactant-gas-to-inert-gas ratio relative to a reactant-gas-to-inert-gas ratio of the first process gas. The second process gas is formed by removing at least a portion of a reactant gas flow from the first process gas.

A method to prepare polymer woven fabric surface with selective oleophilicity or hydrophobicity and oil-oil separation and oil-water separation filter prepared by using the surface. The method to prepare the surface with selective oleophilicity or hydrophobicity includes steps comprising a step to form nano meter sized pores on the surface of the polymer woven fabric surface with micro sized pores through drying type etching; and a step to form selective oleophobic or hydrophobic film on the nano meter sized pores. It is possible to control hydrophobic/oleophobic property according to pore size, material or thickness of the film and this polymer surface with hybrid pores can be used in various areas such as an oil filter for car capable of selective separation of oil-oil mixture and water-oil mixture, disposal of waste oil, treatment of marine oil leakage, and pretreatment of crude oil refinement.

摘要:
A method for combinatorially processing a substrate is provided. The method includes introducing a first etchant into a reactor cell and introducing a fluid into the reactor cell while the first etchant remains in the reactor cell. After initiating the introducing the fluid, contents of the reactor cell are removed through a first removal line and a second removal line, wherein the first removal line extends farther into the reactor cell than the second removal line. A level of the fluid above an inlet to the first removal line is maintained while removing the contents. A second etchant is introduced into the reactor cell while removing the contents through the first removal line and the second removal line. The method includes continuing the introducing of the second etchant until a concentration of the second etchant is at a desired level, wherein the surface of the substrate remains submerged.
