| Research Abstract |
Fabrication of structures with a size of a few tens of nanometer has drawn much interest in the application to the processing of a future generation of ultra large scale integration (ULSI) circuits and new devices in the field of mesoscopic area. Therefore development of non-destructive two and three dimensional analyses is quite important to realize such structures. A bilateral collaboration between Osaka University and Fraunhofer Institut fuer Integrierte Schaltungen has been performed to establish a three dimensional analysis technique with a nanometer resolution. An ion micro probe (or nuclear micro probe) technique using a focused ion beam for three dimensional analysis has been developed at Osaka University and compared with the destructive analysis technique such as TOF-SIMS being used at Fraunhofer Institut using the same samples. The ion micro probe could provide stoichiometry, crystallinity, and impurity distribution in a sample material without material removal techniques.
Following results were obtained :
1. Three dimensional structures such as vacuum micro electronics devices and basic structures for quantum effect devices, fabricated at Osaka University, have successfully been analyzed using non-destructive and destructive techniques. Advantage of the techniques developed in this study was demonstrated.
2. Miniature structures fabricated at Fraunhofer Institute using beam induced chemical and physical processes could have been analyzed with a resolution of 80 nm using the techniques developed.
3. Two and three dimensional mapping (tomography) techniques of material stoichiometry and impurity distribution have been developed using ion micro probes.
