Patent JP-H03233935-A (JP)
Title: Semiconductor substrate
Inventor: KONAKAWA YOSHIKO
IPC: H01L21/322
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a semiconductor substrate which does not produce dust particles, whose gettering effect is high and which maintains the effect even when it is heat- treated by a method wherein an inorganic substance constituted of elements excluding transition metals is deposited on one face of a semiconductor wafer. CONSTITUTION:For example, PBN(pyrolytic boron nitride) or the like which is an inorganic substance constituted of elements excluding transition metals, whose coefficient of thermal expansion is different from that of a disk-shaped semiconductor wager 1 and which displays a heat-resistant property is deposited on a face other than the surface 2a of the semiconductor wafer 1 by using a CVD method. Thereby, a stress is generated on a face 2b on one side of the wafer; a microscopic heat-induced defect and heavymetal impurities are confined in a crystal lattice strain caused by diffusing atoms in the inorganic substance into the face 2b on one side of the semiconductor wafer from a deposition layer 4 and in an oxygen-precipitated defect caused by a precipitation action by atoms. Thereby, it is possible to obtain a semiconductor substrate in which uneven parts do not exist on the face 2b on one side of the wafer, which does not produce dust particles, whose gettering effect is high and which maintains the gettering effect even when it is heat-treated.
