Title: Heat treatment and semiconductor single crystal substrate
Inventor: HABUKA HITOSHI
IPC: H01L21/205
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To fix a temperature to be reached by a semiconductor single crystal substrate at the time of heat treatment so as to unify a crystal quality of a semiconductor crystal substrate to be subjected to heat treatment by controlling a heating output according to reflectance of the back of a semiconductor single crystal substrate. SOLUTION: In the case of performing heat treatment by direct radiation heating at least on the back side of a semiconductor single crystal substrate W, a heating output is controlled according to reflectance of the back of a semiconductor single crystal substrate W. For instance, back reflectance of a silicon single crystal substrate W to e subjected heat treatment one by one is measured in advance for being compared so as to fluctuate a heating output value of an infrared lamp 16 in proportion to a fluctuation width of a value of the back reflectance of every silicon single crystal substrate W.  That is that in the case of large reflectance of the back of the silicon single crystal substrate W a heating output of the infrared lamp is increased and on the contrary in the case of small reflectance of the back of silicon single crystal substrate W, heating output of the infrared lamp 16 is decreased for performing epitaxial growth.

Title: Ignition device for pulsation burner
Inventor: EJIRI SUSUMU
IPC: F23Q3/00
Filed: 1987-03-04
Abstract: PURPOSE:To enable positive ignition from various kinds of gases to be performed by a method wherein when an igniting operation is started, an electrical energization for an ignition plug is delayed by a certain time after releasing a solenoid value for use in supplying fuel gas. CONSTITUTION:When a pulsation combustion is started, a control circuit 12 may release a fuel gas supplying solenoid valve 3 through a solenoid valve driving circuit 13 to feed fuel into a combustion chamber and to mix it with combustion air. In turn, the control circuit 12 may drive an igniter 15 under a control of an igniter driving circuit 14 through a delay circuit 4 to ignite mixture gas. At this time, the delay circuit 4 may delay an output from an igniter driving circuit 14 for a specified period of time after releasing of the fuel gas supplying solenoid valve 3. With this arrangement, it is possible to use various kinds of fuel gases and make a positive ignition.

Title: Polishing slurry, its preparation and chemical/mechanical polishing
Inventor: MUROYAMA MASAKAZU
IPC: H01L21/304
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a polishing slurry having excellent dispersibility of polishing abrasive grain, especially useful for flattening in the case of forming a multilayer wiring structure for a semiconductor apparatus. SOLUTION: This method for preparing a polishing slurry comprises mixing and dispersing polishing abrasive grain composed of fine particles of silicon oxide into an aqueous solution of potassium hydroxide and mixing and dissolving a finely granulated polyimide resin containing a carboxyl group as a hydrophilic group in the dispersion. Since the polishing slurry is provided with thixotropic properties by the addition of the polyimide resin so as to stabilize the dispersibility of the polishing abrasive grain, a polishing rate will not drop even if allowed to stand and preserved for a long time. Consequently, in using after the preservation, an operation for stirring the slurry to recover the dispersibility of the polishing abrasive grain is not required.  For example, an interlayer insulating film for a semiconductor apparatus is flattened by the polishing slurry, so that the same or better polishing result than that in a conventional polishing slurry can be obtained.

Title: Device for converting x-ray into light
Inventor: SEKIGUCHI TADASHI
IPC: H01J31/50
Filed: 1985-03-13
Abstract: PURPOSE:To enhance spatial revolving power through a simple construction, by attaching a magnetic field generator to a device for converting X-rays into light, so that the generator produces a magnetic field parallel with an electric field. CONSTITUTION:A magnetic force line generator 10 is provided around the case 2 of an image intensifier 1 of the parallel flat plate type. X-rays having passed through an examined object are applied to an X-ray image input surface 3 so that the X-rays are changed into a light image by a fluorescent surface 3a, and photoelectrons are emitted from a photoelectric surface 3b. The photoelectrons are changed, by a fluorescent surface 5a, into light corresponding to the energy of the photoelectrons. The light is then changed into photoelectrons by a photoelectric surface 5b so that an output image is made on a fluorescent surface 4. The generator 10 produces a magnetic field parallel with an electric field generated by applying a voltage to the input surface 3, a photoelectron emission plate 5 and the fluorescent surface 4. The spread of the photoelectrons emitted in random directions from the photoelectric surfaces 3b, 5b is thus suppressed to much enhance spatial resolving power.
