Abstract

PURPOSE: To make it possible to raise the first crossover voltage of a scanning side face by laminating continuously and compounding the second porous layer on the first porous layer.
CONSTITUTION: Metallic mesh 24 is expanded throughout target support frame 8, and target support film 25 consisting of aluminum and silver is formed between grids. Next, aluminum is vaccum-evaporated to form signal electrode 10, and argon is led in to fill up magnesium fluoride in an evaporating boat, thereby forming the first porous layer 11. Next, the pressure of argon is increased to fill up silver in the boat, thereby forming the second porous layer 26. After that, a mask corresponding to the electron beam scanning region is inserted, and silver is evaporated as metallic layer 27 only in the target non-scanning region.
