Abstract
We have studied silicon-on-insulator (SOI) materials with two different
ion beam analysis methods. The SOI samples were implanted with boron and
hydrogen ions. After implantation the wafers were annealed, and some of
them were bonded to thermally oxidized silicon wafers. The damage in
silicon single crystal due to ion implantations has been studied by
Rutherford Backscattering in the channeling mode (RBS/C). The content of
the ion-implanted hydrogen has been studied by elastic recoil detection
analysis (ERDA) method. The strength of the implanted region after
thermal annealings were measured with the crack opening method. The
boron implantation before hydrogen implantation resulted to shallower
implantation depth and lower splitting temperature than in samples
implanted with hydrogen only. The boron implantation after hydrogen
implantation did not influence the splitting temperature and RBS spectra
showed that B implantation drove the H deeper to the sample.
