Ohmic metallizations on semiconductors such as In0.53Ga0.47As and GaAs
have been analyzed by cross-sectional transmission electron microscop
y. To obtain a lattice image of multilayer structures in the high-reso
lution mode, a cross-sectional specimen preparation procedure was deve
loped. The phase formation after thermal treatment of the ohmic contac
ts has been studied by applying different microanalytical techniques.
The results have been utilized for improving the metallurgical stabili
ty and the electrical properties of the contacts. (C) Elsevier Science
