Title: Method of dividing wafer
Inventor: KIKUCHI KIYOTAKA
IPC: H01L21/301
Filed: 1991-04-24
Abstract: PURPOSE:To provide a dividing method wherein fine semiconductor fragments produced from a fracture face in a scribing operation do not adhere to a wafer and an electrode or the like is not damaged. CONSTITUTION:A first adhesive tape 3 is fixed to the rear surface of a wafer 1; fine flaws 4 are formed in positions to be divided; a second adhesive tape 5 whose adhesive power is lowered by irradiation with ultraviolet rays is pasted on the surface of the wafer; the rear of the wafer is pressurized via the first adhesive tape by means of an elastic-substance roller 7. The second adhesive tape is stripped after it has been irradiated with the ultraviolet rays. Thereby, since the surface of the wafer is covered with the second adhesive tape, fine semiconductor fragments produced from fracture faces do not come into contact with the surface of the wafer. In addition, the fragments from the fracture faces are removed while they have adhered to the second adhesive tape, and divided wafers (chips) can be handled easily.

Abstract: PURPOSE:To dispense with any priming water by making a pressure head difference caused by what water in an intake tank is pumped up to a discharge tank with a pump, act on a suction pipe and thereby raising a pressure head inside the suction pipe. CONSTITUTION:An outlet 5 of an intake tank 3 is connected to a suction port of a pump 6, and a discharge port is connected to an inlet 8 of a discharge tank 7. When an on-off valve 10 is closed and the pump 6 is driven, water inside the intake tank 3 is pumped up to the discharge tank 7, and a head inside the suction pipe 10 is raised, thus a water level goes up. When the pump 6 is stopped, water flows back to the intake tank 3 from the discharge tank 7. When this operation is repeated, the pressure head inside the suction pipe is raisable, thus any priming water can be made unnecessary.

Filed: 1980-08-31
Abstract: PURPOSE:To eliminate the deviation of printing by nullifying the signal of dot pulse only during the peirod when printing is deviated by play of the mechanism when printing is made in reversed direction. CONSTITUTION:The moving speed of printing head in the space direction is accelerated by preliminary running in the rising part at the time of start in the section T1, restored to its steady speed in the section T2, and then decelerated and stopped in the section T3. Printing is made within the section Tp in the section T2 so that the intervals of dots are kept constant. The section T2 corresponding to the first one place at the printing time in the reverse direction is for correction for deviation. After the printing head 5 is moved to te right direction, a delivery screw 3 is reversely turned in the direction of arrow a3 and reversely direcred dot pulse begins to generate. But, the printing head 5 does not move reversely due to the play X of sliding portion, etc. Thus, dot pulse generated in the section is nulified and the deviation of printing is prevented.
