发明名称 Apparatus and method for inspecting predetermined region on surface of specimen using electron beam
摘要 This invention concerns an apparatus and a method for observing and inspecting a predetermined area in a surface of a sample by use of an electron beam. The apparatus according to this invention comprises an MCP for multiplying a secondary beam emerging from the surface of the sample. The apparatus and method employ a CCD TDI array in order to increase the lifetime of the MCP, and special scan control is carried out in the observation and inspection operation. In addition, the apparatus according to this invention has various structures for enabling correction for positional deviation of the sample and high-speed processing.
