Abstract
ABSTRACTNickel structures have been deposited on large (300 μm diameter), thin (1400 to 3000Å) single crystal (111) silicon membranes. On annealing, the nickel-silicon reaction generates strain which can be partially accommodated through buckling of the membrane, a mode of strain relief not available on bulk wafers. Examples of such buckling are presented in this paper. Features of the silicide structures observed include thin epitaxial Ni2 Si that grows on clean surfaces during deposition, vertical and lateral growth of NiSi2 into the membrane from nickel dots, and the absence of interfacial dislocations between NiSi2 and silicon, probably due to the stress relief.
