Title:
【発明の名称】ゲッター物質を用いることにより電界放出デバイス内に制御された雰囲気を創生し且つ保持する方法
Document Type and Number:
Japanese Patent JPH09502832
Kind Code:
A
Abstract:
A Field Emitter Device (FED) having a substantially reducing atmosphere is described. The atmosphere in a FED can be maintained substantially free of oxidizing gases and includes a partial pressure of hydrogen between about 1x10-7 millibar (mbar) and 1x10-3 mbar. In one embodiment, a non-evaporable getter material previously charged with hydrogen gas is placed inside the FED before the FED is sealed. The non-evaporable getter material can be charged by exposure to hydrogen gas at a pressure between about 1x10-4 and about 2 bar. Subsequently, the components forming the FED are sealed, and the FED is evacuated and hermetically sealed to the outside atmosphere.
