Title: Manufacture of semiconductor device
Inventor: TAKIZAWA RITSUO
IPC: H01L21/322
Filed: 1982-05-24
Abstract: PURPOSE:To prevent the variation in the specific resistance of a semiconductor device by performing an intrinsic gettering a semiconductor which contains the specific quantity of oxygen content at a low temperature. CONSTITUTION:The oxygen content necessary to cause an intrinsic effect depends considerably upon a combination of heat treating temperature and time in the steps, and the variation in the specific resistance produced at a low temperature treatment of 650-800 deg.C has a correlation to the oxygen content. If the oxygen content is 33ppma or less, the variation in the specific resistance does not almost occur. It is possible to control the oxygen content to a value equal to or less than 33ppma and effective to set it to approx. 25-30ppma.
