METHOD OF INHIBITING DISLOCATION GENERATION IN SILICON DENDRITIC WEBS

METHOD OF INHIBITING DISLOCATION GENERATION IN SILICON DENDRITIC WEBS

A method of tailoring the heat balance of the outer edge of the dendrites adjacent the meniscus to produce thinner, smoother dendrites, which have substantially less dislocation sources contiguous with the dendrites, by changing the view factor to reduce radiation cooling or by irradiating the dendr...

Zusammenfassung:A method of tailoring the heat balance of the outer edge of the dendrites adjacent the meniscus to produce thinner, smoother dendrites, which have substantially less dislocation sources contiguous with the dendrites, by changing the view factor to reduce radiation cooling or by irradiating the dendrites with light from a quartz lamp or a laser to raise the temperature of the dendrites.
