Out-diffusion of nitrogen from float-zone silicon measured by dislocation locking

Journal article

A measurement of nitrogen out-diffusion from nitrogen-doped float-zone silicon made using a dislocation locking technique is presented. Specimens containing a well-defined array of dislocation half-loops are subjected to identical anneals at 750°C, during which nitrogen diffuses both to the surface and to the dislocations. The specimens are then chemically etched so as to remove different thicknesses of material from the surface. The stress required to move the dislocations away from the nitr...
