Abstract:
Method for introducing a limited amount of mercury into a fluorescent lamp during manufacture thereof includes the steps of forming the lamp with an exhaust tubulation therein open at an end thereof, exhausting the interior of the lamp through the exhaust tubulation, placing a body of metal material not reactive with mercury in the exhaust tubulation open end, the body having a coating of metal which amalgams with mercury, over a selected surface area of the body, and having mercury on the coated area of the body, such that a limited amount of the mercury is retained by the metal coating, and sealing the open end of the exhaust tubulation, whereby the amount of mercury retained on the body and introduced into the lamp is limited by the surface area of the metal coating on the body.
Abstract:
To attain an increase in production speed and suitable for mass production in a substrate processing operation such as film formation requiring a hermetic atmosphere. A substrate processing method for performing a predetermined processing on a substrate is provided, which includes the steps of: arranging a surface of the substrate to be processed in a hermetic atmosphere; evacuating said hermetic atmosphere; and performing a predetermined processing on the substrate, in which the processing step is conducted after moving the evacuated hermetic atmosphere from the station for evacuation to a ifferent station.
