Abstract: PURPOSE:To enable an alpha-BNC:H film of stable quality containing no pollution to be formed by a method wherein a chamber is highly vacuumized by driving a turbopump system in excellent exhaust capacity in the process of exausting any residual air. CONSTITUTION:A chamber 11 is exhausted by vacuumizing itself using a turbopump 23, a mechanical booster pump 24 and a water sealing pump 25 in order of 10<-5> Torr as necessary; then reacting gas feeding is started; simultaneously a transfer valve 27 is manipulated to close the turbopump system 23; resultantly the reacting gas is trasferred to an exhaust system comprising the mechanical booster pump 24 and the water sealing pump 25 through a bypass 26 similar to the conventional examples. When the specified degree of vacuum is attained, the feeding of CH4, NH3 and B2H6 gas is started; the turbopump is closed; the bypass 26 is opened to exhaust the chamber 11 by the conventional exhaust system only. Finally, the exhaust is fed to a specific exhaust system 28. Through these procedures, a film can be formed under no influence of any residual gas in the chamber to improve the reliability of an X-ray mask.

Title: Zoom lens
Inventor: HASHIMURA JUNJI
IPC: G02B13/18
Filed: 1990-07-20
Abstract: PURPOSE:To compose the zoom lens for a compact LS camera of a small number of lens elements and to reduce the cost by composing the lens system of three lens groups and providing aspherical lenses in a 1st and a 2nd groups. CONSTITUTION:The zoom lens consists of three components, i.e. the 1st lens group with positive refracting power, the 2nd lens group with positive refracting power, and a 3rd lens group with negative refracting power and the air intervals of the respective lens groups are varied to vary the focal length of the whole system. Then one aspherical surface is used in each of the 1st lens group and 2nd lens group. When the aspherical surface is used as the lens front surface (aspherical surface A) on the most object side in the 1st lens group, the aspherical surface A prevents a comatic aberration from being generated at the peripheral part of the image plane to compensate a spherical aberration within a tertiary (tertiary of aberration theory). When the aspherical surface is used for the lens on the most image side (aspherical surface B), the aspherical surface B compensate the spherical aberration (spherical aberration of, specially, high order). Further, when a both-surface aspherical lens is used in the 1st lens group, various aberrations which can not be suppressed only by the front surface are compensated by the rear surface.
