ABSTRACT:
Large surface silicon crystal layers with a columnar structure are produced by directing a plurality of spaced-apart cooling gas streams arranged relative to one another to correspond to a desired columnar structure and positioned a relatively short distance above a free surface of a silicon melt surface located below such system so that a spontaneous seed crystal formation occurs at the regions or areas of the melt immediately below each gas stream and thereafter the affected melt surface is solidified, and then removing the so-formed plate or disc-shaped silicon body from the melt. Dopant material can be incorporated within the so-formed plate or disc-shaped silicon crystal so that a pn-juncture parallel to the surface of such plate or disc is attained.
