Extract

A variety of materials such as semiconductors, metals, and insulators have been analyzed by use of the Hitachi IMA-3 ion microprobe analyzer. From the depth profile of a GaAs/AQ GaAs superlattice(50Å), a depth resolution of 45Å was obtained at 2350Å below the surface. The stable depth profile of a multilayer plastic film was obtained by using the negative ion beam(O) as a primary ion for charge neutralization. Further, the usefulness of the total ion monitoring method for correcting the changing factors of secondary ion intensity is demonstrated.
