Migration of implanted indium in silicon as a function of thermal annealing

Abstract
The study of indium implantation in silicon has gained considerable interest because of its potential in producing high value resistors in integrated circuits. We have studied the redistribution of indium as a function of high-temperature anneal and dose. While the data show some anomalous redistribution, the bulk of the implanted indium remains undisturbed supporting a trapping mechanism during solid phase epitaxial growth for high-temperature thermal anneals up to 1050 °C.
