[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1 to 3, an integrated cabinet 100 with an air supply device 140 is provided for an embodiment of the present invention, and includes: the cabinet 110, the plurality of work modules 120, the plurality of fans 130, the temperature sensor, and the blower 140. The cabinet 110 includes a plurality of first openings 111, and the plurality of first openings 111 include an air inlet 112 and an air outlet 113; the working module 120 is located in the cabinet 110; the plurality of fans 130 include: a transverse fan 131 and a longitudinal fan 132, wherein the transverse fan 131 is arranged in the first opening 111 and/or the working module 120, and the longitudinal fan 132 is arranged between any two adjacent working modules 120; the temperature sensor is arranged on the working module 120 and used for detecting the temperature of the working module 120 in real time; the blower 140 is disposed at the air inlet 112 and/or the air outlet 113.

According to the temperature of the operation module 120, the horizontal fan 131 adopts different rotation speeds, and the air blowing device 140 adopts different opening and closing modes. For example, the temperature of the operating module 120 is low, the rotation speed of the transverse fan 131 is low, and the second rotating plate 142 with the self-hanging structure is not easily blown up by the airflow of the transverse fan 131, so that the second rotating plate 142 is opened to an excessively small extent or is not opened, and the first rotating plate 141 is opened; when the temperature of the working module 120 is moderate, the rotation speed of the transverse fan 131 is moderate, the second rotating plate 142 can be blown up by the airflow of the transverse fan 131, at this time, the first rotating plate 141 can be closed, the air inlet and the air outlet are realized through the second rotating plate 142, the driving device 143 is not needed to control the opening and closing of the first rotating plate 141 or adjust the opening angle, so that the energy is saved, and compared with a louver type ventilation opening, the second rotating plate 142 is selectively opened through the opening and closing of the transverse fan 131, so that the targeted heat dissipation is realized, the energy is saved, and the heat dissipation effect is better; when the temperature of the working module 120 is high, the second rotating plate 142 can be opened only by blowing as required, the air outlet and inlet effects can be influenced to a certain extent, and the first rotating plate 141 is opened preferentially at a large angle to avoid the situation that the opening degree of the second rotating plate 142 is too small, so that the air inlet amount and the air outlet amount are ensured, and the heat dissipation effect is improved.

Preferably, the first opening 111 includes, for example: a first stop 114.

Preferably, the second stopper 141b is a slope surrounding the second opening 141a, so that no friction is generated during the separation of the second stopper 141b from the second opening 141a, which facilitates the air flow of the transverse fan 131 to blow the second rotating plate 142 to open. Accordingly, when the transverse fan 131 corresponding to the second rotary plate 142 is not turned on, the second rotary plate 142 naturally hangs down, and the second stop member 141b does not get stuck during the contact of the second rotary plate 142.
In a specific embodiment, the first rotating plate 141 and the second rotating plate 142 of the same blower device 140 rotate in the same direction, i.e., the first rotating plate 141 and the second rotating plate 142 of the air inlet 112 are both open to the inside; both the first and second rotating plates 141 and 142 of the outlet 113 are opened to the outside.

Further, the rotation axis of the second rotating plate 142 is disposed at one side of the second opening 141a facing the rotation direction of the second rotating plate 142, that is, the rotation axis of the second rotating plate 142 and the rotation axis of the first rotating plate 141 are located at the same side. The rotating shaft of the second rotating plate 142 may also be connected to the first rotating plate 141 through a shaft seat and disposed above the second opening 141a, and the rotating shaft is rotatably connected to the second rotating plate 142 through an oblique connecting block, so as to prevent the rotating shaft from generating a gap in the second opening 141a, which may cause dust to enter the cabinet 110 from the second opening 141a when the second rotating plate 142 is closed.
In a specific embodiment, the driving device 143 is connected to either end of the rotation shaft of the first rotation plate 141 to control the rotation of the first rotation plate 141, and the driving device 143 is fixed to the cabinet 110.

For example, when the locking end rotates from the first rotating plate 141 to the second rotating plate 142, both sides of the second rotating plate 142 are fixed by the locking assembly 144 and the second stopper 141b, respectively, thereby preventing the second rotating plate 142 from rotating.
Preferably, the locking assembly 144 is driven by a motor to rotate, which is not described herein.

step S1: the temperature T of each working module 120 of the integrated cabinet 100 is detected in real time through the temperature sensor, and whether the temperature T of each working module 120 meets the heat dissipation condition T > T is judged1；
Step S2: recording the working module 120 meeting the heat dissipation condition as a first working module, turning on the transverse fan 131 corresponding to the first working module, and turning on the locking component 144 of the blowing device 140 corresponding to the first working module;

wherein, T1Is a first temperature threshold; the transverse fan 131 corresponding to the first working module comprises the transverse fan 131 arranged on the first working module and/or is arranged onThe transverse fan 131 is arranged on the first opening 111 corresponding to the first working module.
In a specific embodiment, referring to fig. 7, step S1 includes step S11: the real-time detection of the temperature T of each working module 120 of the integrated cabinet 100 by the temperature sensor, for example, every TxAnd acquiring the temperature of the corresponding working module 120 through the temperature sensor. Each operating module 120 may be provided with a plurality of temperature sensors, and the temperature T of the operating module 120 is obtained by an average value of the plurality of temperature sensors.
Preferably, t isxThe time is 3 to 10min, for example 5 min.
It should be noted that, the determination of whether the temperature T of each operating module 120 satisfies the heat dissipation condition T > T1That is, each operation module 120 is controlled individually, and when the operation module 120 corresponds to a plurality of air blowing devices 140 or a plurality of fans 130, the corresponding air blowing devices 140 operate simultaneously and are in the same open/close state, and the corresponding fans 130 rotate simultaneously and are in the same rotation speed.
In a specific embodiment, the determination of whether the temperature T of each of the work modules 120 satisfies the heat dissipation condition T > T1Examples include: step S12, if the temperature T of all the working modules 120 satisfies T ≦ T1At this time, x is higher in temperature1Each working module is a second working module, and the first rotating plate of the air supply device corresponding to the second working module uses a0Angle open, close the remaining first rotation plates 141, every t0Time, the transverse fan 131 corresponding to the second working module is counted by n1Running at a rotational speed t1Time.
Wherein, t0Is a preset interval time; t is t1Is a first preset time; the transverse fan corresponding to the second working module comprises the transverse fan arranged on the second working module and/or the transverse fan arranged on the first opening corresponding to the second working module.
It should be noted that the temperature T of all the operating modules 120 satisfies T ≦ T1At this time, the temperature in the cabinet body 110 is lowAt this time, the second working module is always kept in a heat dissipation state, so that the temperature of the cabinet body 110 can be stabilized at a lower level; accordingly, the transverse fan 131 may also be operated at a relatively low rotational speed at this time. At this time, the corresponding first rotating plate 141 is turned on, so that the second working module can be in an air circulation state, and compared with the case of turning on only the second rotating plate 142, the case that the second rotating plate 142 cannot be blown up or turned on less due to a low wind speed of the transverse fan 131 can be avoided, and the heat dissipation effect is poor. Wherein, T1From 15 to 25 deg.C, for example 18 deg.C.
Preferably, a0Is in the range of 10 ° to 30 °, for example 30 °.
Preferably, the number of the working modules 120 performing heat dissipation is, for example, 30% to 50% of the total number. For example, when the number of the operating modules 120 is 6, the first rotating plate 141 and the transverse fan 131 corresponding to 2 to 3 operating modules 120 having the highest temperature are turned on.
Preferably, t is0And t1For example, the value of (2) is in the range of 2 to 5 min.
Further, tx=t0+t1That is, x having the highest temperature T in the period of detecting and determining the heat dissipation condition for the temperature T of each operating module 1201The transversal fan 131 corresponding to each work module 120 performs exactly one operation and pause. For example, txOn the basis of =5min, t0For example, 2min, t1For example, 3min, which is not limited herein.
Preferably, the rotation speed n of the transverse fan 131 is set at this time1For example 600 RPM.
In step S2, the heat dissipation condition T > T is satisfied1The first operating module of (1) needs to increase the rotation speed of the transverse fan 131 to obtain a better heat dissipation effect. At this time, the second rotating plate 142 of the blowing device 140 can be stably turned on by the airflow of the horizontal fan 131, so that the locking assembly 144 is preferentially turned on to open the second rotating plate 142, thereby reducing the number of times the driving device 143 controls the first rotating plate 141, and energy can be saved by controlling the air intake and the air exhaust through the second rotating plate 142 of the self-hanging type. And areAnd, only when the temperature of the first working module is too high, the first rotating plate 141 is re-opened, and the first rotating plate 141 is opened at a larger angle, thereby satisfying the heat dissipation requirement.
In a specific embodiment, the working module 120 that records that the heat dissipation condition is satisfied is a first working module, the transverse fan 131 corresponding to the first working module is turned on, and the locking component 144 of the air blowing device 140 corresponding to the first working module is turned on, for example, including: step S21: recording the number of the first working modules as x2Judgment of x2And x1The magnitude relationship of (1); step S22: if x is satisfied2＜x1X at the highest temperature T2-x1Every t of the transverse fans 131 corresponding to the low-temperature working modules0Time in n1Running at a rotational speed t1Time. The working module 120 which records that the heat dissipation condition is met is a first working module, the working module 120 which does not meet the heat dissipation condition is a low-temperature working module, and the transverse fan 131 corresponding to the first working module continuously operates. Wherein x is1Is a first work module quantity threshold.
When x is to be mentioned2＜x1When the temperature of the working modules 120 is higher than the temperature of the working modules 120, the temperature of the cabinet 110 is not high, and the working modules 120 which do not satisfy the heat dissipation condition still need the transverse fan 131 to dissipate heat at a lower wind speed to maintain a lower temperature; when x is2≥x1When the temperature of the working modules 120 is higher, the working modules 120 which do not satisfy the heat dissipation condition are fewer, the overall temperature of the cabinet 110 is higher, and the heat dissipation effect of the transverse fan 131 which adopts a lower rotating speed is not significant enough, so that the corresponding transverse fan 131 does not need to operate.
In a specific embodiment, in step S3, the determining step determines whether the temperature T of the first operating module satisfies a heat dissipation improvement condition, and if so, increases the opening angle of the first rotating plate 141 of the blowing device 140 corresponding to the first operating module, and/or increases the opening angle of the first rotating plate 141 of the blowing device 140 corresponding to the first operating moduleThe turn-on speed of the transverse fan 131 includes: judging whether the temperature T of the first working module meets the heat dissipation lifting condition T > T2，T2Is a second temperature threshold, wherein T2From 25 to 35 deg.C, for example 30 deg.C.

The first working module exchanges heat through the second rotating plate 142, and the second rotating plate 142 does not need to be controlled to be opened or closed by a motor, so that an energy-saving effect is achieved.
Preferably, the rotation speed n of the transverse fan 131 is set at this time2For example 1200 RPM.
On the other hand, the first working module that satisfies the heat dissipation improvement condition performs step S32: the angle of the first rotating plate 141 corresponding to the first operating module is a1Starting, the rotating speed of the transverse fan 131 corresponding to the first working module is n3And (4) opening. Wherein n is3＞n2For example, n3=1800RPM。
It should be noted that, at this time, the first working module has a higher heat dissipation requirement, and the second rotating plate 142 needs to be pushed by the airflow to be opened, so the second rotating plate 142 may hinder the air from entering and exiting to some extent, and the second rotating plate 142 is difficult to be opened to the maximum state by the airflow pushing, so the first rotating plate 141 is opened by the driving device 143 to open a proper angle according to the heat dissipation requirement, and the first opening 111 is larger than the first opening 111, which can further improve the heat exchange efficiency.
Preferably, the first and second liquid crystal materials are,

Wherein (T)0-T)/(T0-T2) For the temperature change rate, when the temperature change rate is small, the angle of the corresponding first rotation plate 141 is at a1The angle of the heat exchanger is increased, thereby improving the heat exchange efficiency.
Further, k is, for example, 0.5, axFor example, 45 deg., where axThe value of (b) can be adjusted according to the external environment temperature, and is not limited herein.

In a specific embodiment, the determining whether the temperature T of the first operating module satisfies a heat dissipation improvement condition, and if so, increasing the opening angle of the first rotating plate 141 of the blowing device 140 corresponding to the first operating module, and/or increasing the opening speed of the transverse fan 131 corresponding to the first operating module, for example, further includes: the first working module meeting the heat dissipation lifting condition is arranged at intervals of t2Time, if T still satisfies the heat dissipation promotion condition T > T2Then, judge (T)0-T)/(T0-T2) If < m% is satisfied; if (T) is satisfied0-T)/(T0-T2) < m%, go to step S33: the rotating speed of the transverse fan 131 corresponding to the first working module is increased by n on the current basisxMaximum elevation to nmax(ii) a If not (T)0-T)/(T0-T2) < m%, go to step S34: maintaining the current rotating speed of the transverse fan 131 corresponding to the first working module; wherein m% is a temperature change rate threshold value; n isxPresetting a rotating speed increasing quantity; n ismaxIs a rotational speed threshold.
It should be noted that, when the temperature change rate is low, the heat exchange efficiency can be further improved by increasing the rotation speed of the corresponding transverse fan 131.

Note that RH is1As humidity threshold, e.g. RH1= 40%. The humidity sensor in the cabinet 110 obtains the relative humidity RH and the humidity threshold RH of the cabinet 1101A comparison is made.
Further, the humidity at the bottom of the integrated cabinet 100 is low, air is supplied through the air supply device 140 of the air inlet 112 at the bottom of the integrated cabinet 100, and is dehumidified through the dehumidification device 150, so that dry air can be introduced into the cabinet body 110; the humidity at the top of the integrated cabinet 100 is high, and the air is supplied through the air supply device 140 of the air outlet 113 at the top of the integrated cabinet 100, so that the humidity in the cabinet body 110 can be effectively reduced.

Note that t is4Is a fourth preset time, t4The value of (a) is in the range of 0.5min to 3min, for example 2 min.
For example, the relative humidity RH satisfies the humidity adjustment condition RH > RH1While the temperature T of any operating module 120 satisfies T > T2The transverse fan 131 normally rotates at the rotation speed n3Starting and adjusting the rotating speed according to the temperature change rate; and satisfies the temperature T and T > T2Until the relative humidity RH continues for t4The time satisfies RH ≤ RH1And when the dehumidification is finished, the integrated cabinet 100 can control the air supply device 140 again according to the heat dissipation condition and the heat dissipation lifting condition.
