Title: Stage moving method and target coordinate value calculation method for alignment mark
Inventor: HIRACHI KAZUYUKI
IPC: G05B13/00
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a method for calculating a target coordinate value approximated to the real value of an alignment mark in short time and for moving a stage to the target coordinate value. SOLUTION: For the stage moving method, the present coordinate value of the alignment mark and the present value of a PSD (phase synchronized detection) signal are measured. Then, a temporary target coordinate value is calculated based on the inclination of a primary linear part, which is previously decided in an S-shaped curve in the PSD signal, the present coordinate value and the present PSD signal value. Then, the stage is moved based on the temporary coordinate value. When the temporary target coordinate value is within a prescribed range by the movement of the stage, the new coordinate value and the new value of the PSD signal are measured for the prescribed number of times and the average value is calculated. Then, the new target coordinate value is calculated based on the new average coordinate value and the new PSD signal value.  Then, the stage is moved based on the new target coordinate value.

Title: Vertical treatment apparatus
Inventor: TAKAGAKI TETSUYA
IPC: H01L21/22
Filed: 1987-04-15
Abstract: PURPOSE:To prevent attachment of foreign material to a material to be treated even if the foreign material falls due to friction between members or thermal fatigue of the members, by covering a guiding region, which inputs and takes out the material to be treated, with a dustproof cover. CONSTITUTION:An input/output region B, which is located beneath a reacting tube 2, is covered with a dustproof cover 17. Thus attachment of falling foreign material 16 to the surface of a wafer 5 is prevented when the wafer 5 is inputted and taken out. An exhaust pipe 13, which is connected to the reacting tube 2, is linked with an overlapped structure having a specified interval. When reacting gas 4 from a treating region S is exhausted, the concentration of the reacting gas 4 can be made low. A part between the dustproof cover 17 and the reacting tube 2 has a labyrinth structure, and an exhausting chamber D and the input/output region B are communicated. Thus intrusion of the foreign material into the input/output region B from the exhausting chamber D is prevented. In this way, the vertical treating apparatus having high treating reliability can be obtained.

Title: Alignment mark
Inventor: MATSUDA SHUICHI
IPC: H01L21/30
Filed: 1986-04-18
Abstract: PURPOSE:To ensure a high-precision alignment for mask patterns in the presence of optical stationary waves by a method wherein the bottom of an alignment mark is designed to incline in the direction of its depth so that stationary waves occur only at one spot even when some are created owing to the thickness of a photoresist film or the like. CONSTITUTION:For the formation of an alignment mark 1a, a substrate 1 in the state of a bare wafer is subjected to an assist etching process, wherein a focus ion beam of gallium ions Ga<+> at an acceleration voltage of 100KeV is employed for blowing a reactive gas SF6 to the surface of the bare wafer. The depth created is smaller from the right end toward the left end. This is accomplished by gradually shortening the time consumed for scanning. By using this technique, the alignment mark 1a may be formed at a desired spot.

Abstract: PURPOSE:To obtain the stable images of good quality without intricating constitution by controlling the quantity of light from a light source thereby performing the residual image removal of a rotator and substantial uniformalization of its potential. CONSTITUTION:When a copying switch is turned on, a predestaticizing charger 24, a lamp 3, primary-, secondary- and transfer chargers 5, 6, 9 and a shutter 25 go on. Pre-coronas, primary-, secondary- and transfer coronas, blank exposure and uniform exposure are applied to the photoreceptor of a rotating drum 2 to clean the remained toner, charge, memory etc. respectively, whereby the preparation for starting copying is made. At this time, the lamp 3 is weak lighting. As the drum makes predetermined rotation, the platen 1 also moves and the lamp 3 emits light strongly, then the shutter 25 is turned off to stop blank exposure which is then changed to image exposure. The blank exposure is performed in order to prevent the occurrence of potential unevenness. Thereby, the always stable transfer images of good quality may be obtained.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To restore a public pit even if it sinks after construction by easily returning a lid receiving frame and a lid to their original heights. SOLUTION: In this protective lid for a public pit, a lid receiving frame 6 is installed via a frame receiving member 5 on a pedestal 3 which is disposed to surround an inner lid 2 at the upper end of the riser 1 of the public pit. At least three screw holes 3c are formed in a flange part 6b inside the lower part of the lid receiving frame 6 and height-adjustment bolts 8 are threadably engaged in the screw holes 6c. A lid 7 is freely removably mounted over the lid receiving frame 6.  Should the pubulic pit sink after construction, the height- adjustment bolts 8 are rotated and threaded in downwards to cause the lid receiving frame 6 to rise relatively within the range of the maximum threadable size of the height-adjustment bolt 8 to enable the surfaces of the lid receiving frame 6 and the lid 7 to be returned to their initial heights at which they are flush with the ambient surface of the ground. Therefore, the public pit can be easily repaired by packing paving material therearound.

Abstract: PROBLEM TO BE SOLVED: To obtain a metal scavenger having obviated such problems that one type of conventional metal scavenger obtained by introducing a functional group such as dithioacid group into a low-molecular amine is excellent in metal scavenging ability, but there are problems in the flocculability or sedimentability of flocs formed, while another type obtained by introducing a functional group into polyethyleneimine is good in the flocculability or sedimentability of flocs formed, but inferior in metal scavenging ability to the former metal scavengers; thus it has been difficult to afford such metal scavengers as the fully satisfy both metal scavenging ability and floc sedimentability; furthermore, conventional scavengers are subject to performance deterioration through functional group decomposition due to the presence of any oxidizing agent and/or acidic substance. SOLUTION: This metal scavenger is obtained by reaction of dicyamdiamide with a vinylinirile-based polymer containing >=5 mol% of nitrile group-bearing polymer unit component to effect introduction of triazine group serving as functional group into the nitrile group portion of the vinylnitrile-based polymer; or this scavenger bears metal-scavenging functional group introduced through substitution with at least one hydrogen atom to the nitrogen atom of the above triazine group.
