Inventor: YAMAGUCHI AKIRA
IPC: H01L21/322
Filed: 2001-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an epitaxial silicon wafer having a sufficient gettering effect without affected by the temperatures during the device process in a p/p+type epitaxial wafer using a substrate with low concentration of oxygen, in order to solve the problem that the gettering perfor mance becomes insufficient when the initial concentration of oxygen of the epitaxial silicon wafer substrate is low because the formation of BMD's (Bulk Micro Defect) is insufficient during the device process and to cope with the recent outstanding trend toward lower temperatures in the process. SOLUTION: After an epitaxial layer is formed on a p/p+type silicon wafer having a medium to low concentration of oxygen and a low resistivity, that is, an interstitial oxygen concentration of less than 13×10<17> (atoms/cm<3> ) and a specific resistance of 0.005 to 0.05 Ω/cm, it is raised in temperature to higher than 1,150 deg.C in an non-oxidizing atmosphere or preferably in the presence of an inert gas such as an argon gas, and after the same temperature is maintained for a few seconds, a process is applied in which it is lowered in temperature to 900 deg.C at a temperature lowering speed of more than 20 deg.C/sec, and if desired, a heating process is applied for depositing oxygen.

Title: Grate of stoker combustion furnace
Inventor: FUJITA KENJI
IPC: F23H3/02
Filed: 2001-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a grate of a stoker combustion furnace being easy to manufacture at low cost and having a long service life. SOLUTION: Water cooling pipes 40 are contained in grooves 41 in a top plate 35 and soldered in place using solder 42. The area of contact between each water cooling pipe 40 and the top plate 35 is thus increased to enhance the efficiency of heat transfer to suitably cool the top plate 35 while increasing joint strength. Since the water cooling pipes 40 are not integral with the top plate 35, the direct effects of cracks, if any, in the top plate 35 on the water cooling pipes 40 are reduced. Further, the grate 30 can be manufactured with the grooves 41 formed on the back of the top plate 35 with such a rough accuracy that clearances form when the water cooling pipes 40 are contained in the grooves.  Since soldering is carried out at the clearances between the water cooling pipes 40 and the top plate 35 with the water cooling pipes 40 contained in the grooves 41 in the top plate 35, complicated operations and high machining accuracy are not required.
