Our successful attempt to design and develop series of room-temperature field ion-scanning tunneling microscopies (RT FI-STMs) is discussed. The great advantages of RT FI-STM are (1) almost simultaneous use of both STM mode and FIM mode is possible without wasting machine time and thermal drift, (2) inspection and manipulation of a STM tip in-situ in the STM system can be performed and, thus, each tip can be used over several months with atomic resolution, and (3) a well-characterized tip ensures very high (~100%) success rate in STM imaging with a known resolution. Some examples are given.
