Description of the invention () S-1 Field of invention: This invention relates to a device used in semiconductor factories to monitor the amount and size of particles The monitoring device that can switch between different detection points to test the dust situation of the detection point can not only use the existing component combination to complete the improvement, but also use less cost to complete the conventional functions. 5. 2 Background of the invention: For semi-conducting Zhao Gongma, the control of dust is a very important subject, because the dust is a major factor that affects the quality of semiconducting snakehead products. As far as is known, a plurality of measuring points can be selected in a dust monitoring device, and a dust collector is set up at the point to collect the dust sample at the point; the above dust sample turns into a multi-point switch ( Manifoldswitch), and switch the dust samples delivered at each detection point in a fixed time; then, a particle counter (Particle counter), the dust samples delivered to measure the dust size, quantity and other data at that point, and The data is converted into an electronic signal and sent to a monitor; the monitor receives the above-mentioned electronic signal, and displays the electronic signal of the dust sample on the screen of the monitoring device using a monitoring software. The above-mentioned dust monitoring device will increase the number of multi-point switches and dust counters used as described above. The paper standard of the dust counter is applicable to China National Standard Falcon (CNS) A4 specification (210X297mm) (please read the precautions on the back and then fill out this page).

B7 Fifth, the description of the invention (), the sales reimbursement is about 600,000 Taiwan dollars per unit, which is a very expensive instrument; every time the detection point exceeds 12 points, a dust counter must be added. There is a need for improvement in terms of cost efficiency. 5-3 Purpose and summary of the invention: In view of the background of the invention described above, the conventional dust monitoring device is not cost-effective when there are many detection points. The present invention proposes an improved method for the conventional device, so that when the detection point is increased, the device can be purchased with only a small cost to purchase the necessary equipment, and the same function can be achieved. The first scam describes the dust monitoring device used in the prior art, and 36 detection points are displayed in the circle, which are received by the dust collectors 101, 102, 103, 104, 105, and 106, respectively. 12. The dust samples at points 13, 24, 25, and 36; the dust samples at points 1 to 12 are sent to a multipoint switch 111, and the dust samples at points 13 to 24 are sent The dust samples from the 25th to the 36th points of a multi-point switch 1 1 2 'are sent to a multi-point switch 113. The above multi-point switches 111, 112, and 113 are controlled by control signals from lines 122, 124, and 126, respectively, and output their dust samples to dust counters 131, 132 through lines 121, 123, and 125, respectively. , And 133. The above dust counters 131, I ”, and the size of this paper apply to the Chinese National Standard Falcon (CNS) A4 specification (2i〇x297 mm) (please read the precautions on the back before filling out this page). Consumer Cooperation Du Printed A7 B7 V. Description of the invention () and 133 separately tested the dust information (such as the number of dust, the size of the dust, etc.) of the input dust sample. After converting this information into an electronic signal, it then passed the line 141 , 142, and 143 are output to the monitor display generating device 151 for display. The monitor display generating device 151 is a computer system, and the monitoring information produced is displayed on the monitor of the computer system. In operation, the dust is sampled at a detection point every fixed time, for example, the dust sample is taken at the first point in the first minute (using the dust collector 101), and the sample is taken at the 12th minute Dust sampling (completed with dust control device 102); at the 13th minute, the dust sample was obtained by the dust collector 103, and so on, and the dust was sampled again at the first point at the 37th minute. Knowing that the multi-point switches 111, 112, and 113 used in the system are Aerosol Manifold AM-12 (hereinafter referred to as AM-12) produced by PMS (Particle Measuring System Inc.); due to the AM- 1 2 models can only switch 12 detection points, so under 36 detection points must use 3 AM-1 2; relative to the number of multi-point switch 'dust counter (Particle counter) to The same quantity is also required. However, since the dust counter uses a laser gun to test the received dust samples by scanning, everyone who knows this art knows that the cost of the laser grab is very expensive, so The price of the dust counter is high, and the conventional dust monitoring device is not cost-effective in the case of a large number of detection points.

Invention description () From the second circle, we can see that the dust counter (partic | e counter) has been reduced to one, and no matter what the number of detection points is, only one dust counter is needed. All that is required is the dust-proof tube switcher 231 and the controller 232, which has greatly reduced the cost. Furthermore, when describing the internal structure of the dust collector switch 231 and the controller 232 later, it will be understood that the above additional device can be completed only by using widely used off-the-shelf electronic components. Compared with the dust counter, The extra cost is negligible.

The dust control switch 231 includes three solenoid valves 301, 302, and 303, which are used to control the switching of the pipelines 221, 223, and 225, and one Su-wheel electric release 304 is used as the solenoid valves 301, 302 and The relay station 30 3 receives the control signal from line 2 33 to control the on / off operation of the above solenoid valve. In addition, the off-the-shelf solenoid valve and the Su-lun relay can be used to complete all actions of the dust collector switch 231 without additional changes. The fourth ring is the internal structure circle of the controller 232, and the lines 222, 224, 226, and 242 connected to the controller 232 are also shown in the figure.

The actual operation situation can be explained by the fifth circle. The T1 in the circle represents the sampling time of the above prohibited dust samples collected by each dust collector (hereinafter referred to as "sampling cycle"), each 12 sampling cycles is _ cycle encounter period, TM1, TM2, and TM3 respectively represent 3 cycles.

In the preferred embodiment of the present invention, at the end of each cycle period, the dust sample at a detection point is sent to the dust counter 251 using the dust collector switch 231 and the controller 232. For example: after the end of TM1, the controller 232 will send a control signal (via line 224), so that the dust sample obtained at the 13th point (accepted by the dust collector 203) is sent to the pipeline 223; at the same time, the dust collector switch 231 also receives the control signal from the controller 232 (from line 233>, and receives the dust sample of line 223, and sends the wire dust counter 251 through line 241.

Invention Description () The actual operation of circle 5 is as follows: At the beginning, The dust suppressor 201 collects the dust sample at the first and second price measurement point in the sampling period T1; after the end of 12 sampling cycles, that is, at the end of the cycle TM1, the controller 232 sends a control signal and controls the dust collector 2〇3 Start Z as a long dust sample, the control signal makes the dust collector switch 231 switch the internal pipeline to make it receive the dust sample from the 13th detection point collected by the dust prohibitor 203. Another 12 has passed After a sampling period, that is, when the cycle period TM2 ends, the controller 232 sends a control signal and controls the dust collector 2〇5 to start collecting dust samples. The control signal causes the dust control tube switch 231 to switch. Internal pipeline, so that it receives the dust sample from the Mth detection point collected by the dust prohibitor 205; similarly, after another 12 sampling cycles, that is, when the cycle encounter period ends, the controller 232 Send control letter No., turn around and control the dust collector 201 to start collecting dust samples. The control signal causes the dust tube switch 231 to switch the internal pipeline to receive the dust sample from the first detection point collected by the dust collector 201.
