  • Publication number: 20090068768
    Abstract: A non-destructive and simple analytical method is provided which allows in situ monitoring of plasma damage during the plasma processing such as resist stripping. If a low-k film is damaged during plasma processing, one of the reaction products is water, which is remained adsorbed onto the low-k film (into pores), if the temperature is lower than 100-150 C. A plasma (e.g. He) that emits high energy EUV photons (E>20 eV) which is able to destruct water molecules forming electronically excited oxygen atoms is used to detect the adsorbed water. The excited oxygen is detected from optical emission at 777 nm. Therefore, the higher the adsorbed water concentration (higher damage), a more intensive (oxygen) signal is detected. Therefore, intensity of oxygen signal is a measure of plasma damage in the previous strip step.

  • Patent number: 7458251
    Abstract: A method is disclosed to measure the permeability of films or coatings towards solvents (e.g. water). First a substrate comprising an absorption or container layer is provided, preferably the material is a porous material. To study water permeability, the porous material is hydrophilic or is made hydrophilic by means of e.g. an anneal process. To study the permeability of the film or coating, the coating is deposited on top of the porous material. The substrate comprising the film or coating on top of the absorption or container layer is then brought into a pressurizable chamber subsequently filled with the gaseous substance of the solvent (e.g. water vapor). By increasing/decreasing the vapor pressure in the chamber between zero and the equilibrium vapor pressure of the solvent used, the permeability (penetration) of solvent through the film or coating can be determined. The amount of solvent that can penetrate through the film or coating can be measured by means of ellipsometry, mass spectrometry, etc.
