摘要： The present invention is a method for forming a three point atomic force microscope tip. The method includes forming a substantially longitudinally extending solid tip having a peripheral surface and a forward end surface. Three masks are formed by deposition of carbon upon the solid tip, with a first and second of the masks formed along the peripheral surface, and a third of the masks formed on the forward end surface. The mask covered tip is then etched for a predetermined period of time to remove material from both the tip and the mask. After the predetermined period of time has elapsed, the masks are completely removed, and the removal of material from the tip results in the formation of three spikes which are pointed to the location from which the masks were removed.

摘要： A plane of a treatment liquid holder having a number of through holes faces a treatment surface of a substrate. A treatment liquid is held between the treatment surface and the liquid holder by utilizing a surface tension of the treatment liquid. Since the treatment liquid is applied only to the treatment surface, an extremely small amount of treatment liquid suffices for the treatment. In addition, since a fresh treatment liquid can be used in every treatment, cross-contamination is suppressed and the treatment can be performed with safety at a low cost.

摘要： In order to provide the processing required to prevent a semiconductor substrate from becoming contaminated or damaged, without heating it in a kiln, a combustion flame of a gas that is a mixture of hydrogen and oxygen is applied to the surface of the semiconductor substrate, so that only the substrate surface is heated. Oxidizing or reducing processing can be provided by varying the ratio of hydrogen to oxygen. A device that enables this processing method comprises a first conduit (6) for guiding hydrogen; a second conduit (7) for guiding oxygen; a flame generation means (5) for combusting the hydrogen and the oxygen in a mixed state to generate a downward-pointing flame over a range wider than the diameter of a semiconductor substrate (1) that is being processed; a flow regulation means (8) and (9) provided midway in each of the first tube and the second tube, for regulating the fluid passing through each of the first tube and the second tube; and a conveyor means (2), (3), and (14) for conveying the semiconductor substrate that is being processed, provided below the flame generation means.

摘要： An evacuation apparatus and method using a turbomolecular pump having a rotor provided with a plurality of rotor blades and a spacer provided with a plurality of stator blades so that gas molecules are sucked in from a suction port, compressed and discharged from an exhaust port of the turbomolecular pump is disclosed. A heat exchanger is provided at the suction port side of the turbomolecular pump to freeze-trap gas molecules from being cooled by a helium refrigerator.The gate valve is disposed upstream of the heat exchanger and is provided in a suction pipe which extends between the vacuum vessel and the turbomolecular pump. In exhausting the vacuum vessel, the gate valve is opened and, in this state, the turbomolecular pump and the helium refrigerator are run. During regeneration, the gate valve is closed, the turbomolecular pump is run, and the heat exchanger is heated by means of a heater or by operation of the helium refrigator being suspended, thereby sublimating molecules freeze-trapped in the heat exchanger.
