摘要:
A semiconductor material, such as elemental silicon, is deposited on heated rod-shaped mandrels from a reactive gas stream capable of pyrolytically depositing silicon wherein the gas stream is regulated in such a manner that the silicon deposition rate remains constant per cubic centimeter of mandrel surface throughout the deposition process.
摘要:
Molten silicon is controllably fed into a nip between spaced-apart rollers, converted into a wide ribbon of a desired thickness by passing through such nip and then solidified. The solidified silicon ribbon is then severed into plate-shaped bodies of desired dimension for use in the manufacture of solar cells.
摘要:
A smooth surfaced amorphous silicon layer useful in semiconductor technology is produced by pyrolytic deposition of elemental silicon onto a heated mandrel along with simultaneous pyrolytic deposition of at least one other element selected from Groups IV through VIII and which is non-semiconductive and does not function as a conductivity determining dopant.
摘要:
Si monocrystals of the n-type are produced by zone melting polycrystalline Si rods under conditions sufficient to produce monocrystal rods, measuring the specific conductivity of such monocrystal rods and subjecting such monocrystal rods to a controlled radiation by thermal neutrons based on the measured conductivity to produce a desired degree of n-conductivity in the ultimately attained rods.
