SELECTIVE CARBON DEPOSITION
A method for depositing carbon on a substrate in a processing chamber includes arranging the substrate on a substrate support in the processing chamber. The substrate includes a carbon film having a first thickness formed on at least one underlying layer of the substrate. The method further includes performing a first etching step to etch the substrate to form features on the substrate, remove portions of the carbon film, and decrease the first thickness of the carbon film, selectively depositing carbon onto remaining portions of the carbon film, and performing at least one second etching step to etch the substrate to complete the forming of the features on the substrate.
METHOD FOR PRODUCING A COATING ON AN OBJECT AND CORRESPONDINGLY PRODUCED COATED BODY
A method for producing a coating on an object and a correspondingly produced coated body, in particular a cutting insert such as a cutting plate for machining processes. The coating with one or more coating layers is applied to the object. At least one Al.sub.1-xTi.sub.xN coating layer is deposited using a CVD method, wherein nitrogen in the Al.sub.1-xTi.sub.xN coating layer can be partially substituted. In order to obtain a coating layer with a highest possible proportion of cubic phases, the Al.sub.1-xTi.sub.xN coating layer is deposited in the presence of a sulfur-containing gas.
MULTIFUNCTIONAL COATING, METHOD OF MANUFACTURING THEREOF, RELATED COATED ITEMS AND USES
A method for forming a coating on a substrate is provided, the method comprises: using a molecular layer deposition (MLD) process depositing at least one layer directly or indirectly on a surface, and an atomic layer deposition (ALD) process, depositing an inorganic film on/over the at least one layer. In the formed coating conditions are established which allow unbound, unreacted and/or partially reacted precursors to enter chemical interaction with harmful environmental species penetrated into the coating at defective sites thereof and seal said defective sites through formation of a sealing compound. A laminate coating, uses thereof and coated items are further provided.
