Abstract: A power supply circuit for plasma generation by which a large quantity of generated plasma can be smoothly obtained without increasing the sizes of an apparatus. An electric discharge generating electrode is composed of two or more first electrodes and one or more second electrodes. An LC series circuit is provided by connecting a capacitor C and a coil L in series between one of outputs of an alternating high voltage generating circuit which generates an alternating high voltage to be applied between the electrodes of electric discharge generating electrode, and the first electrode. When electricity is discharged in one of the electrode pair, voltage drop is suppressed by the coil, and since electric discharge from the other electrode pair is induced without being disturbed, a large quantity of plasma can be smoothly generated by common use of the alternating high voltage generating circuit.

Abstract: Diamond fine particles having porous structure known in a high thermal resistance and low dielectric constant film has a high thermal conductivity and is expected as an insulating film for multiplayer wirings of a semiconductor integrated circuit device. A liquid composition of diamond fine particles, which are raw material of the film, is unstable as colloid, resulting in low reproducibility and yield in the production of films. It becomes possible to impart a very low viscosity and improved stability to the colloid liquid composition of diamond fine particles by containing a small amount of amine. If necessary, a thickener may be used to adjust the viscosity appropriately, so that various kinds of application systems can be used. A low dielectric constant film having a relative dielectric constant of about 2.5 can be thus obtained. Further, the liquid composition may be utilized as an abrasive for finishing.

Abstract: The present invention realizes a nanotube probe with high durability that can be manufactured in short time with less impurities adhered to the holder sustaining the nanotube. The nanotube probe according to this invention is constructed by fastening a nanotube 8 on the protruded portion 4 of a cantilever by way of at least two partial coating films 12a and 12b. One or more additional partial coating films may be formed in the intermediate area between these two partial coating films. Each partial coating film is formed by irradiating electron beam 10 on the position where the nanotube 8 is in contact with the protruded portion 4 of the cantilever. The partial coating films are separated not to overlap each other. By minimizing the size of partial coating film as well as by narrowing down the beam diameter, coating time may be further shortened. With the beam diameter narrowed down, excessive deposit of impurities can be put under control.

Abstract: A scanning microscope probe in which a palladium covering film is formed on the surface of the protruding portion of a cantilever, and the base end portion of a nanotube is disposed in contact with the palladium covering film with the tip end portion of the nanotube protruding to the outside, thus allowing the tip end to be used as a probe needle end for detecting signals. A coating film is formed to cover all or part of the surface of this base end portion, and the nanotube is thus firmly fastened to the cantilever. Since the base end portion adheres tightly to the palladium covering film, both of them are electrically continuous. This palladium covering film allows, as an electrode film, the application of a voltage to the nanotube or the passage of an electric current through the nanotube, showing also good adhesion to the nanotube and cantilever.

Abstract: By using a novel method, the exposure time of the photosensitive paste layer is reduced and the exposure fineness of the layer is improved, thereby developing a highly fine circuit substrate of high density having a thermal resistance at a reasonable cost. A circuit substrate is manufactured as follows. A photosensitive paste containing photoresist and a circuit material is applied onto a substrate surface so as to form a photosensitive paste layer (4). This photosensitive paste layer (4) is plotted by a laser beam (8) so as to form a plotted area (7). The photosensitive paste layer (4) is developed and an exposed area (4a) or an unexposed area (4b) is removed so as to form a circuit pattern (17). This circuit pattern (17) is sintered to form a circuit pattern (20) composed of the circuit material. It is possible to form a highly fine circuit pattern of high density by laser beam plotting.

Abstract: Diode-type nanotweezers including a first arm and a second arm that project from a holder and are opened and closed by an electrostatic force so as to hold a nanosubstance. The first arm is formed by a gate nanotube fastened at its base end to the holder, and its tip end protrudes from the holder. The second arm is formed by a nanotube diode fastened at its two base ends to the holder and have a diode characteristic portion at its tip end. Diode current and diode voltage applied between the base ends of the arms shows a non-linear diode characteristic such as varistor and rectification. When a gate voltage is applied between the gate nanotube and the nanotube diode, the arms are controlled and a grip strength for a nanosubstance held by the arms is detected by changes in the gate voltage or the diode current.
