A method for manufacturing a semiconductor device may include: forming a main magnetic field having an axis, and forming a subsidiary magnetic field substantially parallel to the axis; applying an alternating current along a path between the main and the subsidiary magnetic fields; allowing a gas to flow along a flow path along the path of the current so that a gas plasma is generated from the gas; providing the gas plasma into a chamber separated from a position where the gas plasma is generated; and performing a process for manufacturing a semiconductor device by employing the gas plasma.
Abstract:
A method for fabricating a CMOS image sensor includes developing a semiconductor substrate provided with metal pads with tetramethylammonium hydroxide (TMAH), to etch the metal pads. In accordance with the method, it is possible to realize normal output of materials, which were previously scrapped due to problems including pad corrosion, appearance defects and bonding pad issues which may occur in the process of fabricating CMOS image sensors. As a result, advantageously, it is possible to reduce wafer scrap and improve product yield.
Abstract:
A thrust magnetic bearing system separates magnetic circuits of electromagnets from those of permanent magnets so that each permanent magnet produces a bias magnetic field while each electromagnet functions only to control the position of a rotating body, thereby achieving desired displacement and current stiffness without flowing a bias current through the electromagnet. The magnetic bearing system includes a thrust displacement sensor and a thrust magnetic bearing to float a disk floating body based on displacement information detected through the displacement sensor. The magnetic bearing includes a donut permanent magnet, a pair of electromagnets connected in series to form an inductor at both sides of the donut permanent magnet, and a pair of magnetic poles provided opposite each other outside the pair of electromagnets. The magnetic bearing floats the floating body through a bias magnetic flux generated by the permanent magnet and a control magnetic flux generated by the electromagnets.

Abstract:
Disclosed herein is a muscular motion simulating system that is capable of simulating a force-displacement characteristic of an ideal muscle model through the use of a large displacement magnetic actuating unit supported by means of linear springs. The muscular motion simulating system comprises a base plate mounted to a virtual muscle part in a dummy in the longitudinal direction thereof, a moving body connected to a wire withdrawn from the virtual muscle part such that the moving body can be slid on the base plate when the position of the wire is changed due to an external impact so as to output the moved distance of the moving body, a load cell connected to the lower part of the moving body for measuring a load depending upon the moved distance of the moving body, a fixing plate fixed to the lower end of the base plate while being protruded outwardly, a load-adjusting unit disposed between the load cell and the fixing plate for outputting positional information to increase or decrease the load applied to the load cell by means of a biasing force of the magnetic field, and a control unit for controlling the actuation of the load-adjusting unit such that load applied to the load cell corresponds to the muscle strength according to the moved distance of the moving body with reference to the positional information inputted from the load-adjusting unit.
