Title: Electron source manufacturing device

IPC: H01L21/027
Filed: 2002-11-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electron source manufacturing device with a reduced size and reduced moisture absorption into an inner wall of a vacuum container, suitable for productivity with improved production speed, capable of evacuating in a short time.  <P>SOLUTION: The electron source manufacturing device is provided with an air flow generating means 2 forming an air curtain between a lifted vacuum container 1 and a substrate 3. The air curtain generated by the air flow generating means has a velocity vector in a direction almost perpendicular to the substrate located at the position where the air curtain blows. The more air molecules having the velocity vector in the vertical direction forming the air curtain, the more effective a blocking function of the air curtain becomes. However, because of the existence of the substrate with which the air curtain collides, the air molecules having the velocity vector in the vertical direction is reduced by the recoil of the air molecules hitting the base board. Namely, the blocking function of the air curtain is lowered and intrusion of water molecules into the vacuum container is increased. Accordingly, an upper limit of the velocity of the air curtain is set.  <P>COPYRIGHT: (C)2004,JPO

The wet steam W created by the boiler 2 and introduced through the wet steam introduction pipe 9 into the circulation container 8 spirally rises along the inside face of the circulation container 8 because it has a high temperature. At this time, part of the wet steam W is liquefied by heat exchange with the circulation container 8 and the centrifugal force of a circulating flow, and so it is dewatered. Less droplets are produced by cooling the dry steam blow pipe 10 when the dry steam D is released from the dry steam blow pipe 10 to the outside, than conventional ones, therefore restricting the discharge of hot water from the end of the dry steam blow pipe 10.  <P>COPYRIGHT: (C)2004,JPO
