Latest Patents

One of Ikebe's latest patents is the "Secondary-ion mass spectrometry apparatus using field limiting method." This inventive apparatus includes an optical system for primary ions, a sample chamber, and an optical system for secondary ions. It features a total ion monitor (TIM) positioned between an electric sector and a magnetic sector of the secondary ion optical system. The TIM image can be continuously observed or monitored through a CRT, providing valuable insights into the charging state of the sample surface. The apparatus also incorporates an adjustable component for quantitatively managing the charging state.

Another key patent is the "Method and apparatus for neutralizing an accumulated charge on a surface of a specimen." This innovative method addresses the issue of accumulated charge that arises during examination in a scanning electron microscope (SEM) or a scanning ion microprobe mass analyzer (IMA). By utilizing an electrically conductive thin film deposited on a portion of the specimen's surface, this technique effectively neutralizes the charge generated by the primary charged particle beam. As a result, the resolution of the SEM is enhanced by allowing higher accelerating voltages, leading to more reliable data in IMA assessments.
