Abstract

PURPOSE:To prevent an apparatus form suffering damage by providing means for detecting a voltage different from a specified input voltage, when said voltage is applied to said apparatus, and means for automatically breaking an input-applying circuit. CONSTITUTION:When a voltage higher than a desired input voltage is applied to a terminal 21, a relay 22 for detecting an input voltage is operated to turn ON a contact switch 23. The terminal 26 of a breaker 25 is brought to a short circuit state to break input and output power terminals 21, 27. Thus, no overvoltage is applied to a load 24, so that said load 24 can be protected from damage.

(Prior Art) Conventional semiconductor manufacturing equipment is generally protected against input power by using fuses, non-fuse breaker contactors, and the like. These overvoltage and overcurrent protection functions cut off the input voltage by blowing a fuse or turning off a non-fuse breaker by detecting an overcurrent flowing through the load that exceeds the rated current. In addition, contactors, etc. used with fuses and non-fuse breakers, etc., will not operate at input voltages below, for example, 85% of the rated voltage, and the input TL source will not be supplied to the equipment, causing the equipment to operate at a voltage lower than the rated voltage.

Or, at the time of expansion, modification, or maintenance, input MLR
Wiring, switching, rewiring, etc. are performed. In particular, technology related to semiconductor manufacturing equipment is rapidly advancing, and expansions and modifications are frequently performed, making cable wiring within and between equipment extremely complex, and the number of cases of wiring errors is increasing. For example, AClooV may be applied to an AC200V input power line. In this case, as mentioned above, the wiring contactor will not operate and the device will not be ri i when the rated voltage is below the predetermined value, but the AClo
If AC200V is applied to the oV input power supply line, the rated TL of the semiconductor manufacturing equipment
Since the current is set to be relatively large, overcurrent detection cannot be performed immediately, and there is a problem in that detection is only performed after one of the devices becomes short-circuited due to heating or the like. In this case, the device that has been short-circuited is generally damaged and must be removed, repaired, and re-inspected.
The loss of time and cost was enormous. This invention was made to improve the above-mentioned points, and aims to provide a safe semiconductor manufacturing equipment that protects the equipment from damage even if a different voltage higher than the desired input voltage is accidentally applied to the input power supply line. It is something to do.

An interface (1]) that transfers the wafer between the coating device (1) and the exposure device (not shown), a developer (12) that applies a developer to the wafer and develops it, and takes out the wafer from the line to check the finished state of development. It is constructed by freely combining units such as a pick-up (13) for receiving and receiving processed wafers into a cassette, and a receiver (14) for receiving and taking processed wafers into a cassette. The controller and adhesion (6) (not shown) of these units are, for example, AClooV? ! For example, use an AC 200V power supply for the motors of the scrubber (4), coater (8), developer (12), etc., and heaters such as the high temperature oven (5) and hot plate (9). ) For example, a three-phase 200cm blower is used. In this way, in the coating device (1), single-phase AC 100V, 200V and three-phase AC 200V are applied.
Several different voltages are used. For this reason, semiconductor manufacturing equipment, such as coating equipment, is provided with a safety mechanism. As shown in Figure 1, the protection circuit for the single-phase AC100V input power line as this safety mechanism is as shown in Figure 1.

The contact switch (23) of the relay (22) is configured to be turned on when the relay is in operation and turned off when it is not in operation. In addition, a cutoff means (24) for cutting off the input power supply from the controller, adhesion (6) unit, etc., such as a test voltage breaker (25), is installed between the input power supply voltage (21) and the output voltage (27).

Next, the operation will be explained. First, when a desired input voltage, for example, AClooV, is applied to the input type R voltage (21), the relay (22) that detects the input voltage detects that the applied voltage between the input power supply voltages (21) is within the AC100Vt' operating range, for example. Since the voltage is not between 170V and 230V, it does not operate and therefore the contact switch (23) remains off. Therefore, when the switch of the breaker (25) is turned on or when it is in the on state, the voltage applied to the input power supply voltage (21) is output as is to the output power supply voltage (27), and the load (2

Next, you may accidentally enter a voltage higher than the desired input voltage, e.g. AC200V.
is applied to the input 'R source voltage (21), the relay (22) that detects the input voltage operates because the voltage between the input type R voltage (21) is AC200V, which is within the operating range, and the contact is closed. The switch (23) is turned on. Therefore, the test voltage 26) of the breaker (25) becomes short-circuited. Therefore, even if the breaker (25) is turned on, the breaker (25) turns off immediately, and when the breaker (25) is turned on, the test voltage (26) is shorted. At the same time, the breaker (25) turns off, and the input voltage R voltage (21)

As a result, each unit serving as a load (24) will not be damaged. In the above embodiment, the cutoff tl! Although a breaker with test screws was used as the structure, a contactor may also be used. In this case, as shown in Fig.
The contact switch (23a) of the input voltage detection relay (22&) is connected in series with the excitation coil (30) of (29) and provided between the input voltage fln4 elements (21). Also, at this time, when the relay (22a) is operating, the contact switch (
