Abstract: PURPOSE:To improve insulating properties between wiring layers by etching an inter-layer insulating layer on a bump formed on the surface of the wiring layer, exposing the bump and burying the bump in an insulator. CONSTITUTION:A first Al wiring layer 5 is thermally treated with the object of the formation of an excellent ohmic contact with a diffusion layer 2, thus promoting the formation of bumps 8 in the surface of the wiring layer 5. An inter-layer insulating layer 6 is shaped. A resist is applied, and etching is conducted before mask alignment for forming a through-hole 9. The inter-layer insulating layer 6 is etched above the bumps 8 to project the bumps 8. The resist is removed, a liquefied insulator is applied, and the protruded bumps 8 are buried 10 while the surface is smoothed. A solvent is gotten rid of through heat treatment, an insulating film 11 is shaped, a resist is applied, mask alignment for shaping the through-hole 9 is performed, and etching is conducted. A second Al wiring layer 7 is formed through the same technique as the first Al wiring layer 5 after said treatment.

Abstract: PURPOSE:To erase an desirable space from an image and reduce the throughput of an image processing and to improve the measurement accuracy by irradiating fluid with different-wavelength light rays from plural different positions and photographing the part where the light rays overlap each other. CONSTITUTION:A controller 202 outputs an image input start instruction to image processors 203a and 203b and turns on TV cameras 107a - 107b to photograph a flow passage. Further, the controller 202 sends an indication for light emission to a laser light source 201 and stops the light emission a certain time later. Then the controller 202 sends an end indication to the processors 203 and turns off the TV cameras 107. Flow track image data is converted into a digital signal, which is sent to the controller 22 to find the flow velocity in the photographed space from the position relation between the flow track data from the image and the cameras. Consequently, only an optional position in the space is lighted with the overlapping light rays and photographed to reduce the throughput of the image processors and improve the measurement accuracy.

The crushed material is conveyed to a floatation sorting part 22 through a pipeline 18 and sorted by floatation in the gas phase in the floatation sorting part 22. The crushed material is separated into heavy material and light material and these are discharged. Therefore, since waste is merely thrown in the miniature crushers 14 and separated into heavy material and light material, a large quantity of waste is efficiently treated. When the miniature crushers 14 are dispersed and arranged in the suitable positions, transfer of waste to the crushers is made simple. Furthermore, heavy material is sorted to magnetic metal, nonmagnetic metal and nonmetal by an electromagnetic sorting machine 48. Accordingly metal contained in waste is effectively recovered and a treating device for waste is useful in resource recycling.

Abstract: PURPOSE:To specify an optional FF circuit and to trace its output signal continuously by latching the value of an FF circuit by a latch circuit and outputting the value of the FF circuit. CONSTITUTION:The FF circuit whose value is to be read is specified firstly. Then, a control signal 9 is set to '1' and the value of each FF circuit is inputted to a latch circuit 8. Then a test is taken. Namely, a mode control signal 4 is set to '1', a control signal 9 is set to 'phi', and an optional value is set in each FF circuit in synchronism with a clock signal 6 from a scan input terminal 5. When the signal 4 is set to 'phi', a signal outputted from a combinational logic circuit 2 is inputted to a next-stage FF circuit in synchronism with the signal 6. At this time, only the circuit 8 which latches '1' turns on a transmission gate 11, so the value of the specified FF circuit is read out from an output terminal 12. Then, the state of variation in the value of the specified circuit is read out from the terminal 12 in synchronism with the signal 6.
