Oxygen transport in Czochralski silicon investigated by dislocation locking experiments
- Abstract:
-
Dislocation locking has been investigated in Czochralski silicon with different oxygen concentrations in the 350-850 °C temperature range. Specimens containing well-defined arrays of dislocation half-loops are subjected to isothermal anneals of controlled duration, during which oxygen diffuses to the dislocations. The stress required to bring about dislocation motion is then measured at 550 °C. The dislocation unlocking stress as a function of annealing time is found to obey distinct regimes....
