Paper Abstract

In this work we discuss two free boundary problems which arise in semiconductor processing. The first problem is concerned with deposition of titanium silicide over a wafer, a process which results in three layers of chemicals: Ti, TiSi and TiSi2 and three free-boundary interfaces. The second problem is concerned with the growth of loop dislocations in crystal, which develop as a result of implanting impurities and rapid thermal annealing. Existence results and properties of the solutions are discussed.
