(US4664745-A)      Semiconductor components tape shaped Si crystals are made using a carrier resistant to a Si melt which is drawn tangentially in a horizontal direction across the melt. The carrier also acts as a crystallisation nucleus.    The carrier has threads having a higher emission factor in comparison to the melt and which serve as crystallisation nucleators. The melt is in a tank of a size such that the contacting length between the melt and the carrier is less than the length of the tank. The contacting length equals the drawing speed of the carrier times the dwell time and the drawing direction is angled at less than 10 deg. to the horizontal. There are reflectors above the melt and heaters below the tank, radiation from the melt surface being controlled so that the surface is maintained at approx. the m.pt. of Si.    USE/ADVANTAGE -   Solar cells mfr. in which crystals of constant thickness and width are obtd. (5pp)l    (JP95055877-B2)      Silicon crystal sheets for semiconductor devices, esp solar cells, are produced using a substrate which is resistant to molten silicon and which is drawn tangentially in a horizontal direction over a silicon melt, the substrate acting simultaneously as a crystallisation seed for formation of a crystalline silicon sheet.    The novel features are (a) the substrate comprises filaments (14) of relatively high emissivity material, which run parallel in the drawing direction; (b) the silicon melt (11) is contained in a tank (8a) of length (l) such that the contact length (L) between the melt and the substrate can be controlled to L=Vz.t (V2=drawing speed, t=dwell time and L is not greater than l); (c) the drawing direction (V2) is angled at less than 10 deg. to the horizontal; and (d) reflectors (17) are arranged over the melt (11) and cooperate with heaters (21) positioned under the tank base to control radiation from the melt surface (22) so that the temp. remains in the region of the melting point of silicon (Tm=1420 deg.C). Appts. for carrying out the process is also claimed.    ADVANTAGE -   Silicon sheet of adjustable width and constant thickness is produced at high drawing speeds.
