A processing system for processing an object (3) is provided, wherein the processing system is adapted, to focus a first energy beam, in particular an electron beam (11), and a second energy beam, in particular an ion beam (21), on a focusing region (29) in which a object (3) to be processed is arrangeable. A processing chamber wall (35) having two openings (38, 39) for traversal of both energy beams and a connector (37) for supplying process gas delimits a processing chamber (45) from a vacuum chamber (2) of the processing system. Processing the object by activating the process gas through one of the energy beams and inspecting the object via one of the energy beams is enabled for different orientations of the object relative to a propagation direction of one of the energy beams.

The invention provides systems and methods for the deposition of an improved diamond-like carbon material, particularly for the production of magnetic recording media. The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp3 carbon-carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma. Such inductive ionization is enhanced by a relatively slow moving (or “quasi-static”) magnetic field, which promotes resonant ionization and ion beam homogenization.
摘要:
A microscopic projection or a characteristic pattern are formed in the vicinity of a region to be processed before processing using electron beam CVD, during processing an image of a region containing the projection or pattern formed by electron beam CVD is captured to obtain a current position of the projection or pattern, a difference between the position before staring and the current position is treated as a drift amount and processing is restarted at a region that has been subjected to microscopic adjustment of the electron irradiation region.

The method for the fabrication of nano scale temperature sensors and nano scale heaters using focused ion beam (FIB) techniques. The process used to deposit metal nano strips to form a sensor is ion beam assisted chemical vapor deposition (CVD). The FIB Ga+ ion beam can be used to decompose W(CO)6 molecules to deposit a tungsten nano-strip on a suitable substrate. The same substrate can also be used for Pt nano-strip deposition. The precursors for the Pt can be trimethyl platinum (CH3)3Pt in the present case. Because of the Ga+ beam used in the deposition, both Pt and W nano-strips can contain a certain percentage of Ga impurities, which we denoted as Pt(Ga) and W(Ga) respectively. Our characterization of the response of this Pt(Ga)/W(Ga) nano scale junction indicates it has a temperature coefficient of approximately 5.4 mV/° C. This is a factor of approximately 130 larger than the conventional K-type thermocouples.

The diamond-like carbon material of the present invention is highly tetrahedral, that is, it features a large number of the sp3 carbon-carbon bonds which are found within a diamond crystal lattice. The material is also amorphous, providing a combination of short-range order with long-range disorder, and can be deposited as films which are ultrasmooth and continuous at thicknesses substantially lower than known amorphous carbon coating materials. The carbon protective coatings of the present invention will often be hydrogenated. In a preferred method for depositing of these materials, capacitive coupling forms a highly uniform, selectively energized stream of ions from a dense, inductively ionized plasma. Such inductive ionization is enhanced by a relatively slow moving (or “quasi-static”) magnetic field, which promotes resonant ionization and ion beam homogenization.
