Title: Method for simultaneously generating oxides with different thickness on same semiconductor substrate
Inventor: PAUL ANDREW LONSHAM
IPC: H01L21/8234
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To manufacture oxides of different thickness on the same semiconductor substrate, by implanting specified ions in the area of the semiconductor substrate having silicon oxide of maximum thickness through a sacrificial silicon oxide layer, increasing the oxidation speed of the semiconductor substrate, and removing the sacrificial silicon oxide layer. SOLUTION: A sacrificial layer 3 is formed on the surface of a semiconductor substrate 1. Chlorine ions and/or bromine ions are implanted in the area of the semiconductor substrate 1 where silicon oxide having maximum thickness is formed through the sacrificial layer 3. Then, the sacrificial silicon oxide layer 3 is removed and the silicon oxide layers 4 and 5 are grown on the surface of the semiconductor substrate 1 by heat oxidation. The growth rate of silicon oxide in the area containing implanted ions is faster than the growth rate in an area which does not contain the implanted ions. Thus, the silicon oxide layer 4 of the area becomes thicker than the silicon oxide layer 5 of the area which does not contain the implanted chlorine ions and/or bromine ions.

Title: Production of semiconductor substrate and solid-state image pickup device
Inventor: TAKIZAWA RITSUO
IPC: H01L31/18
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To produce a semiconductor substrate in which mixing of metallic impurities into an epitaxial layer is suppressed by growing an epitaxial layer immediately before epitaxial growth using a source gas of SiHCl3 without subjecting the surface of the substrate to HCl etching. SOLUTION: An epitaxial semiconductor substrate 3 is produced by growing an n-type silicon epitaxial layer 2, at an epitaxial growth temperature of 1130 deg.C or below, on a CZ silicon substrate 1 using a source gas of SiHCl3 . The failure rate can be improved by setting the epitaxial growth temperature using SiHCl3 at 1130 deg.C or below. The defect rate is reduced at a low temperature because the metallic impurities at the belljar structural part of an epitaxial system or the metallic impurities being admixed through a susceptor are suppressed by lowering the temperature.
