Abstract:
A method of manufacturing a vacuum vessel comprising the steps of:forming plural exhaust holes in a first main substrate at predetermined positions thereon, said first main substrate from which plural first substrates can be obtained;superposing a second main substrate over said first main substrate with said plural exhaust holes formed therein, said second substrate from which plural substrates are obtained, and placing plural getter boxes on said first main substrate so as to cover said exhaust tubes formed therein;hermetically sealing said first main substrate and said second main substrate superposed and, at the same time, hermetically sealing said getter boxes and said first main substrate placed together;evacuating spaces between said first substrates and said second substrates using said plural getter boxes sealed with said first main substrate, and then sealing said plural getter boxes; andcutting said first main substrate and said second main substrate evacuated and hermetically sealed, at predetermined positions, while lead-out electrodes formed on each of said first substrates and lead-out electrodes formed on each of said second substrates are not covered by another substrates, whereby plural hermetic vessels each formed of a first substrate and a second substrate evacuated and sealed together are obtained at the same time.
