摘要： The present invention is a method for forming a three point atomic force microscope tip. The method includes forming a substantially longitudinally extending solid tip having a peripheral surface and a forward end surface. Three masks are formed by deposition of carbon upon the solid tip, with a first and second of the masks formed along the peripheral surface, and a third of the masks formed on the forward end surface. The mask covered tip is then etched for a predetermined period of time to remove material from both the tip and the mask. After the predetermined period of time has elapsed, the masks are completely removed, and the removal of material from the tip results in the formation of three spikes which are pointed to the location from which the masks were removed.

摘要： A plane of a treatment liquid holder having a number of through holes faces a treatment surface of a substrate. A treatment liquid is held between the treatment surface and the liquid holder by utilizing a surface tension of the treatment liquid. Since the treatment liquid is applied only to the treatment surface, an extremely small amount of treatment liquid suffices for the treatment. In addition, since a fresh treatment liquid can be used in every treatment, cross-contamination is suppressed and the treatment can be performed with safety at a low cost.
