Abstract

AbstractWe have investigated the effect of different implantation parameters on cavity formation in the top Si layer in SIMOX structures. Cavities were found to occur in the temperature range between 600 and 675°C. The nucleation and growth kinetics of cavities could be reasonably explained using classical theory, and showed a behavior similar to that of irradiation-induced voids in metals. A similar dependence on instantaneous current and beam scanning frequency was also observed. Post implantation annealing at a temperature of 1150°C for 80 min showed cavities starting to facet, and a threading dislocation density of < 105 cm2. SIMOX structures formed in (111) silicon are also presented.
