Abstract

Buried single-crystal layers of CoSi2 were formed in 150Ω-cm, p-type (100) silicon by high dose implantation of Co followed by furnace annealing. Subsequently, epitaxial silicon layers were grown over these buried CoSi2 layers using SiCl2H2 /HCI/H2. The RBS channel yield of the buried CoSi2 and the epitaxial Si layer is less than 4% indicating good crystallinity of the layer. The defect density in the epitaxial silicon layer as revealed by a dilute Schimmel etch, was in excess of 108 dislocations/cm2 which appear to originate from <111> CoSi2 facets. However, both the substrate/CoSi2 and the CoSi2/epi interface are single crystal as revealed by lattice fringes in TEM. To our knowledge, this is the first report of such a structure.
