    • PROBLEM TO BE SOLVED: To provide standard calibrated leak and a method for manufacturing the same.
      SOLUTION: The standard calibrated leak includes a first substrate and a second substrate formed on the first substrate, wherein a groove, having a prescribed number of divisions and a dimension is formed on a joining surface of at least one substrate to the other substrate. When both the substrates are jointed, the groove is formed as a common hole. A material, where gases cannot pass through, used for the wall of the hole. The angle β, defined by a plane on which an intersection line of both the slopes of the groove, is positioned and one of the slopes is made the same as the angle of field of the crystal face of the substrate on which the groove is formed. The diameter of the thus formed hole reaches nano level. Accordingly, the standard calibrated leak is superior, in controlling the amount of leak in a fine range satisfactorily. The method for manufacturing the standard calibrated leak is also provided.

    • 要解决的问题:提供标准校准泄漏及其制造方法。 解决方案:标准校准的泄漏包括形成在第一基板上的第一基板和第二基板,其中在至少一个基板的接合表面上形成具有规定数量的分隔和尺寸的凹槽 基质。 当两个基板接合时,凹槽形成为公共孔。 气体不能通过的材料用于孔壁。 由沟槽的两个斜面的交线和其一个斜面之间的平面所定义的角度β与形成有槽的基板的晶面的角度相同 。 这样形成的孔的直径达到纳米级。 因此,标准校准的泄漏优良,令人满意地控制精密范围内的泄漏量。 还提供了制造标准校准泄漏的方法。 版权所有(C)2006,JPO&NCIPI
