Patent JP-S63312107-A (JP)
Title: Method for cutting semiconductor chip
Inventor: OSHIMA MITSUO
IPC: H01L21/301
Filed: 1987-06-15
Abstract: PURPOSE:To prevent burrs and warpage from developing on cut-off surface and enhance the dimensional accuracy of the edge by a method wherein grooves, which correspond to cutting lines, are made on the top surface of a wafer stage and the tip part of a blade is fed so as to reach the interior of the groove, when the blade cuts a semiconductor wafer. CONSTITUTION:A semiconductor wafer 13 is placed on a wafer stage 11 so as to align the cutting line 14 of the wafer 13 with the center line of the groove 12 of the wafer stage 11. After that, by sucking the air in vacuum chuck holes 17, the semiconductor wafer 13 is fixed onto the top surface of the wafer stage 11 by suction. By driving a cutting device such as a dicing saw, the semiconductor wafer 13 is cut off by a blade 15 along the cutting line 14. At this time, since the groove 12 has dimensions, which allow to fully house the tapered part 16 of the blade 15, the tapered part 16 can cut in as to completely pierce the semiconductor wafer 13. As a result, neither burr nor warpage develops on the cut-off part of the semiconductor wafer 13, resulting in performing the cutting of semiconductor chip 18 with high dimensional accuracy.

Abstract: PURPOSE:To improve the efficiency of operating an exposure device and the efficiency of manufacturing a non defective substrate by inspecting the exposure state of a check sheet which is exposed by allowing the light emitting means to emit light and deciding a projection pattern of a projecting member. CONSTITUTION:In the case of directly carrying an ultraviolet ray photosensitive type check sheet 22 on an acrylic board 19 of an exposure unit 7 by a traverser unit 5 after carrying out a pattern film 3, the sheet 22 is mounted on the film 3 on the acrylic board 19. The projection pattern of the film 3 is projected on the sheet 22 by temporarily emitting the light of a mercury lamp 20 while keeping the aforesaid state, and the sheet 22 is sensitized. After emitting the light of the lamp 20, the sheet 22 is pulled out so that a circuit pattern which is sensitized on the sheet 22 may be inspected by using a circuit inspecting device or an enlarge lens optical system, and the projection pattern of the film 3 is checked. Thus, the exposure device can be efficiently operated and also the substrate to be exposed can be prevented from being wasted.

The frequency at which 0.1mm. surface shear droop 3c is produced during the punching 3a of the plate 1 is extremely high. A Ti pipe 2 is inserted into the hole 3a of the plate 1 and is subjected to expanding 4 so that the pipe is brought into tight contact with the pipe plate by the expanding 4 from the pipe plate surface allowing the droop 3c to remain. The droop 3c is cutted 10 from the surface of the plate 1 and the surface of the plate 2 is cutted to the depth in a >=0.01mm. range to remove an oxide film 1b, whereafter the contact part between the pipe end and the plate 2 is welded. As a result, the generation of the blow hole and oxidation during welding by the air and oxides in the shear droop part of the punched hole is prevented.

Title: Ink-jet recording apparatus
Inventor: KANDA HIDEHIKO
IPC: B41J2/18
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To enable highly accurate detection for a recording head not discharging which varies large by detecting a temperature change after the recording head is brought to a discharge unable state, and judging that the recording head does not discharge when a value of the temperature change exceeds a threshold value and that the recording head discharges when the value does not exceed the threshold value. SOLUTION: All nozzles are let to discharge preliminarily, and a temperature change ΔT1=T2-T1 is obtained from a temperature T1 of a recording head 213 before the preliminary discharge and a temperature T2 of the head immediately before the completion of the preliminary discharge. A temperature change ΔT2=T2-T3 because of a temperature drop is obtained from a temperature T3 of the head two seconds after the completion of the preliminary discharge. The recording head is then brought to a discharge able state to make the nozzles discharge preliminarily. A temperature change ΔT3 because of a temperature rise and a temperature change ΔT4 because of the temperature drop are obtained. A threshold value ΔTth is set between ΔTL1+ΔT2=30-33 deg.C and ΔT3+ΔT4=18-20 deg.C.  The threshold value ΔTth and a value ΔTi obtained by adding the temperature changes because of the temperature rise and temperature drop are compared with each other. When ΔTi>=ΔTth is held, the recording head is judged not to discharge. When ΔTi<ΔTth is held, the recording head is judged to be normal.
