    • PROBLEM TO BE SOLVED: To provide a method and an apparatus of manufacturing a probe of a scanning probe microscope, which accurately form a minute aperture at the tip of the probe at a low cost.
      SOLUTION: In the method, a metal wire 101 with a sharp section at its edge is covered by a film 102 so that the thinnest portion of the film 102 is on the sharp section of the metal wire 101, and the film 102 is dipped into etchant 202 in such a state that the sharp section of the metal wire 101 is at its lower position thereby carrying out an etching process. The top of the sharp section of the metal wire 101 is exposed by the etching process, and therefore the aperture is formed. The exposure of the metal wire 101 is detected by connecting an electrode 203 with the metal wire 101 and an ohm meter 205 and by observing a value of resistance between the metal wire 101 and the electrode 203, and thereby accurately forming the minute aperture at the low cost.

    • 要解决的问题:提供一种制造扫描探针显微镜的探针的方法和装置,其以低成本在探针的尖端精确地形成微小孔。 解决方案:在该方法中,在其边缘处具有尖锐部分的金属线101被膜102覆盖,使得膜102的最薄部分在金属线101的尖锐部分上,并且膜102 在金属线101的尖锐部分处于其较低位置的状态下浸入蚀刻剂202中,从而进行蚀刻处理。 通过蚀刻工艺使金属线101的尖锐部分的顶部露出,因此形成孔。 通过将电极203与金属线101和欧姆计205连接并且通过观察金属线101和电极203之间的电阻值来检测金属线101的曝光,从而在 低成本。 版权所有(C)2004,JPO
