IPC: B65G59/04
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To enable intensity of a permanent magnet to be easily changed in accordance with the weight change in a magnetic plate by structuring the separator with a storage box having projected lines on the face of the magnetic plate side, with a magnet supporting plate that goes in and out of the box and that consists of a magnetic material, and with permanent magnets attracted onto the supporting plate by a magnetic force. SOLUTION: This magnetic plate separator 10 is so designed that permanent magnets 17 are kept attracted to a magnet supporting plate 15 by their magnetic force and that these permanent magnets 17 together with the supporting plate 15 are freely taken in and out of a storage box 11. In addition, when change is desired for the magnetic force of the entire magnetic plate separator 10, only the permanent magnets 17 are changed. The operation for such change can be performed by merely taking the magnet supporting plate 15 in and out of the storage box 11, with the box 11 remaining attached to an elevating base 20 side; therefore, the change is greatly simplified for the magnetic plate separator 10 in accordance with the change in the weight of the magnetic plate 30.

Title: Electron beam and method for forming ionized metal plasma by using magnetic field
Inventor: ZENGU SHU
IPC: C23C14/34
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To provide an improved method and apparatus for generating plasma in a chamber and sputtering and depositing layers. SOLUTION: The deposition apparatus 100 has at least one pieces of electron guns. The electrons given energy collide against sputter target material atoms, thereby ionizing the target material atoms and losing the energy. The electrons are sent in nearly the tangent direction of chamber shielding walls 106 in parallel with the central axis of the semiconductor producing chamber connected to a substrate 112 with the target 110 and the substrate 112. When the electrons sent thereto lose the energy to ionize the target material atoms, the electrons advance spirally inward in the central region of the semiconductor producing chamber enclosing the central axis and form electron clouds 100 within the central region.  Electromagnets 1010 of the prescribed arrangement are arranged adjacently to the chamber shielding walls 106, by which the collision of the electrons against the chamber shielding walls 106 is prevented.

Title: Manufacture of multilayered thin film
Inventor: ITOZAKI HIDEO
IPC: H01L29/80
Filed: 1986-03-14
Abstract: PURPOSE:To enable the massproduction of multilayered thin films of high average quality to be performed by a method wherein thin films of different quality are laminated alternately on a substrate by repeating the plasma CVD process and the photo CVD process alternately in the same chamber while using a material gas not reacting to the growing process of opposite side thin film or markedly delaying the reaction speed. CONSTITUTION:A Gas A reacting to the plasma CVD process but not reacting to the photo CVD process and another gas B reating to vice versa are mixed with each other to be led in an induction coupling plasma CVD device provided with a chamber 2 with a material gas leading-in port 1 and a discharging induction coil 4 connected to an RF power supply 3 using a device with a light source 6 to irradiate the inside of chamber through an optical window 5. When the plasma discharge and the light irradiation are repeated alternately, the filming process by gas A only is accelerated in case of plasma discharge while the filming process by gas B only is accelerated in case of light irradiation. Furthermore, even if the reaction speed of A, B gas differ markedly from each other, multilayered thin films with sharp interfaces are formed on a substrate 7. Therefore, the gas exchange can be eliminated increasing the productivity by feeding the mixture of A and B gases.
