Title: Method for observing the surface of organic substance by using scanning type electron microscope
Inventor: KITAKOUJI TOSHISUKE
IPC: G01N1/28
Filed: 1983-11-24
Abstract: PURPOSE:To enable the state of the surface of a sample consisting of an organic substance to be accurately observed directly by means of a scanning electron microscope by coating the surface with minute particles having a high efficiency of producing secondary electrons under the conditions of ordinary temperature and ordinary pressure before the direct observation is performed. CONSTITUTION:Before observing the state of the surface of a sample 1 consisting of an organic substance by using a scanning electron microscope, the following procedure is performed. The surface of the sample 1 is coated with a sol prepared by dispersing a minute powder of a metal having a high efficiency of producing secondary electrons such as Be, Mg or Ti (having particle diameters of below 1mum) under the conditions of ordinary temperature and ordinary pressure. Next, the thus obtained body is heated and dried at a temperature which does not allow any thermal deformation to form a surface layer 2. After that, a primary electron beam 3 is irradiated upon the surface layer 2 and a secondary electron beam 4 reflected by the layer 2 is caught by a photomultiplier tube thereby performing image display. As a result, the thermal deformation and denaturation of the sample surface can be avoided since no thin metallic film sputter is used, thereby enabling accurate observation to be performed.
