Title: Manufacture of thin film and device therefor
Inventor: NAKAYAMA TAKEHISA
IPC: H01L21/205
Filed: 1984-02-14
Abstract: PURPOSE:To reduce the number of times of cleaning and thereby to enable a long continuous operation, by providing a film-shaped insulator in proximity to the surface of an RF electrode so that it covers this electrode when a thin film is deposited on a substrate by a plasma CVD method. CONSTITUTION:While a substrate 1 supplied from a supply chamber 9 into a plasma CVD chamber 10 is passed through between an RF electrode 4 and an opposite electrode 3, a row gas supplied from a raw gas blowing port 7 and made to be plasma by a high-frequency wave from the RF electrode 4 is deposited on the substrate 1. A film-shaped insulator 5 is provided so that it covers the RF electrode 4. Thereby it turns hard for the raw gas made into plasma to reach the surface of the RF electrode 4, and thus the amount of a film and powder deposited on the surface of the electrode is reduced, which enables the reduction of a change in the discharge characteristic of the electrode and the consequent reduction of the number of times of cleaning. In addition, the clogging of the blowing port by the film and the powder is decreased, since the raw gas blowing port 7 is transferred to the outside of a plasma light emitting element.

IPC: H02K49/04
Filed: 1985-02-15
Abstract: A load applying device (8) comprises a rotating disc (25) and an electromagnet (27). Since a closed magnetic path is formed by the rotating disc (25) and the electromagnet (27) facing both sides of the rotating disc (25), eddy current is generated efficiently in the rotating disc (25). Since the rotation speed of a load shaft (12) is set to a value higher than a prescribed rotation speed, brake torque applied to the rotating disc (25) by the eddy current generated in the disc functions in a saturated region. Therefore, stable brake torque is applied irrespective of the rotation speed of the load shaft (12).
