摘要:
An apparatus and a method for surface treatment of substrates whereby the quality of substrates can be maintained by preventing excessive plasma treatment of substrates. In carrying out the plasma treatment on a surface of the substrate in a reaction chamber, there are provided an emission spectroscopic analysis device or a mass analyzer, and a controller, so that the energy of ions in plasma is controlled to decrease when, e.g., bromine included in the substrate is detected, and the surface treatment to the substrate is controlled to stop when the removal of impurities of the substrate is detected to end. The bromine once separated from the substrate is prevented from adhering again to the substrate and corroding the substrate. Moreover, ions are prevented from being excessively irradiated to the substrate when the removal of impurities ends, thereby reducing damage to the substrate.

In a board cleaning method for dry cleaning of connection sites on resin-based boards, one or more gases selected from a group consisting of gas that contains a hydrogen element and gas that contains a fluorine element are supplied at least to the connection sites, plasma is generated from the supplied gas, and the boards are cleaned by radicals and ions that are produced by the generated plasma.

摘要:
A magnet filter for removing magnetic metal powder mixed with oil in an oil reservoir or the like which is easily mounted to and dismounted from the oil reservoir. The magnet filter includes a recess formed on a top surface of a screw head having a screw rod studded on its bottom surface and a permanent magnet piece is fitted in the recess.

A dry-etching method for etching materials of the silicon group comprises: providing the material to be etched in a reaction chamber; supplying a mixed gas as the etching gas comprising carbon fluoride, oxygen and another gas wherein the other gas is a partially halogenated hydrocarbon; and thereafter subjecting the etching gas to high frequency electric current so as to make the mixed gas into a plasma whereby the material is etched.

The magnetron dry-etching apparatus has, behind its anode electrode (1) facing an object to be etched positioned on a cathode electrode (2), a rotatable magnet assembly comprising at least one pair of rotatable permanent magnets (12) of narrow-pie-shape, fixed on a common yoke (14) so that different polarity magnetic poles (N and S) are disposed side by side; whereby a uniform magnetic field is formed on a wafer (8) on the cathode (2) upon rotation of said magnet assembly, thereby assuring uniform etching even upon change of gas pressure of other etching conditions.

An on-vehicle data processing system is provided which can cause the vehicle information to be displayed on a display device 10. The on-vehicle data processing system has a mode setting unit 32 for setting the running and stop modes and a data processing unit 34 for computing the mode images. The data processing unit 34 computes the running mode images representing the running states of the vehicle in real time while in the running mode and the stop mode images representing the details of the vehicle information while in the stop mode. Thus, the running mode images, more easily viewed by the driver, can be displayed on the display device in the running mode while the stop mode images, preferentially displaying the contents of the vehicle information, can be displayed on the display device in the stop mode.
摘要:
A magnetic filter consisting of a screw plug having a recess formed at the tip end of its screw rod portion and directed in the axial direction thereof, a rod-shaped permanent magnet piece fitted in the recess, and a non-magnetic member interposed between the permanent magnet piece and an inner circumferential surface of the screw rod portion defining the recess. The rod-shaped permanent magnet piece is magnetized so that magnetic poles may appear on its circumferential surface at diametrically opposite ends of its transverse cross-section, and the rod-shaped permanent magnet piece is axially projected from the tip end surface of the screw rod portion.
