    Abstract

    The formation of palladium silicide on Pd/Ti/Si systems with and without heavy B-doping has been investigated. For comparison, Pd2Si was also formed on Pd/Si systems. The agglomeration of Pd2Si could be retarded in Pd/Ti/Si systems with and without B-doping after annealing at 600 � C. The existence of the Ti layer could improve the thermal stability of Pd2Si. In addition, epitaxial or highly oriented Pd2Si formed in Pd/Ti/Si systems. The two orientation relationships of Pd2Si layers were identified to be Pd2Si½1� 1 10�k Si½ � 1 110� and Pd2Si½110�k Si½001�, and Pd2Si½100�k Si½ � 1 110� and Pd2Si½001�k Si½001�. The formation of strained epitaxial Pd2Si layers was found in Pd/Ti/Si systems. The improvement in the thermal stability of Pd2Si and the formation of epitaxial or highly oriented Pd2Si in Pd/Ti/Si systems were observed with and without B- doping.
