Description

Technical Field

[0002] An ion implanter obtains the desired ions from an ion source and accelerates them to produce an ion beam with energies of several hundred kiloelectronvolts. This beam is used for ion implantation in semiconductor materials, large-scale integrated circuits, and devices, as well as for surface modification and film formation of metal materials. Ion implanters generate high levels of electrical energy during operation, posing a potential safety threat to the surrounding environment. Therefore, a shielded door is typically installed at the implanter's location, and the implanter can only operate when the door is closed. Specifically, when a distribution box is used to power the implanter, the box's control circuit includes a relay associated with the shielded door. This relay must be engaged to activate the distribution box and supply power to the ion implanter. This relay only activates when the shielded door is locked.

[0003] When the area where the ion implantation machine is located needs to be debugged or maintained, the shielding door of the area where the ion implantation machine is located needs to be kept open. In related technologies, a bypass switch is connected in parallel with a relay associated with the shielding door to enable the distribution box to be opened when the shielding door is open.

[0004] In this way, if the bypass switch is damaged by human error and becomes normally closed, the shielding door may not be closed and the ion implanter may be started, which may lead to a safety accident. Summary of the Invention

[0041] To improve the operational safety of an ion implanter, embodiments of the present invention provide an ion implanter power supply control circuit, method, and electronic device. An ion implanter is typically placed in a dedicated machine room, and power is supplied to the ion implanter via a distribution box within the room. The distribution box is a power distribution device specifically designed to distribute electricity. Specifically, the distribution box is connected to a power supply, thereby providing power to various electronic devices connected to the distribution box based on the electricity generated by the power supply. In one possible embodiment, the ion implanter power supply control circuit provided by the present invention can be applied to a distribution box power supply control circuit, which utilizes a power supply to supply power to the distribution box.

[0042] Exemplarily, the power distribution box power supply control circuit includes a first power source, a first bypass switch, and a shield door contactor. The first bypass switch is connected in parallel with the shield door contactor. When the first bypass switch and / or the shield door contactor are closed, the first power source is used to control the power supply to the distribution box. The following describes the present invention with reference to the accompanying drawings:

[0043] like Figure 1As shown, the ion implanter power supply control circuit includes: a second power supply 101, a second bypass switch 102 and the shielding door contactor 103, the second power supply 101, the second bypass switch 102 and the shielding door contactor 103 are connected in series, and the second power supply is a power supply for controlling the operation of the high-voltage power supply of the ion implanter;

[0044] The second bypass switch is configured to remain in an open state when the first bypass switch is closed; and remain in a closed state when the first bypass switch is open, so that the second power supply can be used to power the ion implanter when the shield door contactor is closed.

[0045] According to an embodiment of the present invention, an ion implanter power supply control circuit is provided, and the startup of the ion implanter is controlled by the ion implanter power supply control circuit. Specifically, the ion implanter power supply control circuit includes a second bypass switch, which is connected in series with a shielding door contactor controlled by a shielding door. When the first bypass switch, which is connected in parallel with the shielding door contactor, is disconnected, the second bypass switch is closed, thereby enabling the ion implanter to be powered by a distribution box when the shielding door contactor is closed. When the first bypass switch is closed, the second bypass switch is disconnected, rendering the distribution box unable to power the ion implanter. By controlling the distribution box to power the ion implanter with the second bypass switch, which operates in the opposite manner to the first bypass switch, the startup status of the ion implanter can be used to promptly determine whether the first bypass switch is closed, thereby avoiding potential safety hazards caused by the first bypass switch being normally closed and improving the operational safety of the ion implanter.

[0046] The following is an exemplary description of the ion implanter power supply control circuit provided by the embodiment of the present invention:

[0047] As described above, the ion implanter power supply control circuit provided by the embodiment of the present invention can be applied to the power supply control circuit of the distribution box. In one possible embodiment, the power supply control circuit of the distribution box may include a shielding door contactor, a first power supply, and a first bypass switch. The shielding door contactor may be a relay, which is an electrical control device. When the change in the input quantity reaches the specified requirement, it can cause a predetermined step change in the controlled quantity in the electrical output circuit. The shielding door contactor is a relay associated with the shielding door switch status. Specifically, when the shielding door is not closed, the shielding door contactor is disconnected, and when the shielding door is closed, the shielding door contactor is closed. The shielding door being closed means that the shielding door is locked, and the shielding door not being closed means that the shielding door is not locked. The shielding door refers to a door with a shielding function used to form a closed space in the area where the ion implanter is located. The ion implanter can only be started when the shielding door is in the closed state.

[0048] The first power supply controls the power supply to the distribution box and is typically a 24V DC power supply. The first bypass switch is connected in parallel with the shielding door contactor, and both the shielding door contactor and the first bypass switch are connected in series with the first power supply. When the shielding door contactor and / or the first bypass switch are closed, the first power supply can be used to activate power supply to the distribution box.

[0049] For example, if the ion implanter needs to be used, the shield door can be closed, thereby closing the shield door contactor, turning on the power supply control circuit of the distribution box, and using the first power supply to start powering the distribution box. For another example, if the area where the ion implanter is located needs to be maintained or repaired, the first bypass switch can be closed, so that even if the shield door is open, the distribution box can still be powered by the first power supply, thereby allowing the distribution box to power various electronic devices even if the shield door is not closed.

[0050] In one possible embodiment, the power supply control circuit of the distribution box may also include an air supply passageway, through which gas can be delivered to the distribution box and exhausted through a gas circuit to cool the distribution box, thereby maintaining stable operation of the distribution box. The air supply passageway may include an external air source, an air valve, a solenoid valve, etc. The solenoid valve is connected in series with the external air source, the first power source, the first bypass switch, and the shielding door contactor, and the external air source is connected in parallel with the first power source, the first bypass switch, and the shielding door contactor. The solenoid valve includes a sub-air valve, which energizes upon detecting compressed air, causing the solenoid valve to energize. After the air valve is opened, compressed air begins to be injected. The sub-air valve energizes upon detecting compressed air, causing the solenoid valve to energize. Thus, when the shielding door contactor or the first bypass switch is closed, the first power source is used to power the distribution box.

[0051] like Figure 2 As shown, Figure 2 This is a structural diagram of the power supply control circuit of the above-mentioned distribution box, which includes an external gas source, a first power supply, a gas valve, a solenoid valve, a shielding door contactor (corresponding to contacts 73 and 74) and a first bypass switch (corresponding to contacts 3 and 4). The first bypass switch is connected in parallel with the shielding door contactor, and the first bypass switch and the shielding door contactor are both connected in series with the power supply and the solenoid valve.

[0052] The above-mentioned sub-gas valve is energized when it detects air delivered by an external gas source, and the gas circuit is opened, so that the solenoid valve is turned on. When the first bypass switch or shield door contactor is closed, the power supply control circuit of the distribution box is turned on, and the distribution box SGM PD (source gas box distribution box) starts to supply power to the outside.

[0053] It can be seen from the above-mentioned distribution box power supply control circuit that when the shielding door is closed or the first bypass switch is closed, the distribution box power supply control circuit can be turned on, so that the distribution box can supply power to the outside. When the first bypass switch is damaged and becomes normally closed, even if the shielding door is not closed, the distribution box can still supply power to the ion implanter normally, which will cause the ion implanter to start when the shielding door is not closed, which poses certain safety hazards. In order to avoid this safety hazard, an ion implanter power supply control circuit can be set.

[0054] The ion implanter power supply control circuit may include a second power supply, a second bypass switch, and a shield door contactor, which are connected in series. The second power supply controls the operation of the ion implanter's high-voltage power supply. Exemplarily, the second power supply may be a 24VAC (alternating current) power supply. The second bypass switch is associated with the on / off state of the first bypass switch. Specifically, the on / off state of the second bypass switch is opposite to that of the first bypass switch. That is, when the first bypass switch is closed, the second bypass switch is open, and when the first bypass switch is open, the second bypass switch is closed. Exemplarily, the first and second bypass switches may be switches controlled by NAND or XOR gates with inverted switching phases. The inverted control signal of the first bypass switch serves as the control signal of the second bypass switch, achieving switch phase inversion. The shield door contactor in the ion implanter power supply control circuit and the shield door contactor in the distribution box power supply control circuit are associated with the closed state of the same shield door. The two shield door contactors have the same on / off state and may be the same contactor.

[0055] In the ion implanter power supply control circuit, if the second bypass switch is closed and the shield door contactor is engaged, the ion implanter power supply control circuit can be turned on, and the second power supply can be used to control the ion implanter's high-voltage power supply to begin operation. If the second bypass switch is disconnected or the shield door contactor is not engaged, the ion implanter power supply control circuit cannot be turned on. Because the first and second bypass switches have opposite opening and closing states, that is, when the first bypass switch is closed, the second bypass switch will be open. Therefore, regardless of whether the shield door is closed, the ion implanter cannot be powered, causing the ion implanter to be inoperative. Relevant personnel can determine whether the first bypass switch is closed by observing the operating status of the ion implanter.

[0056] In one possible embodiment, the ion implanter power supply control circuit further includes a high-voltage switch capable of providing precise voltage control and rapid switching for the ion implanter. The high-voltage switch is connected in series with the second power supply, the second bypass switch, and the shield door contactor, and is configured to control the voltage of the ion implanter based on the second power supply. Specifically, when the second bypass switch, the shield door contactor, and the high-voltage switch are closed, the ion implanter power supply is turned on using the second power supply.

[0057] In one possible embodiment, the high-voltage switch may include a high-voltage on switch and a high-voltage off switch, which are connected in series. When the ion implanter is not in use, the high-voltage on switch is disconnected, and the high-voltage off switch is usually closed, at which point the high-voltage switch is in an off state. When the ion implanter is needed, the high-voltage on switch is closed. If the ion implanter needs to be stopped, the high-voltage off switch can be pressed, causing the high-voltage off switch to change from a closed state to an off state, thereby disconnecting the ion implanter power supply control circuit, preventing the ion implanter from being powered.

[0058] In a possible embodiment, the ion implanter power supply control circuit may further include a relay, the relay including a relay coil and a contact pair, the contact pair being connected in parallel with the high-voltage on switch and in series with the high-voltage off switch, and the relay coil being connected in series with the high-voltage on switch and the high-voltage off switch;

[0059] The relay coil is used to energize when the second bypass switch, the shielding door contactor, the high-voltage opening switch, and the high-voltage closing switch are all closed, and to control the contact pair to be attracted, so that when the second bypass switch, the shielding door contactor, and the high-voltage closing switch are all closed and the high-voltage opening switch is disconnected, the ion implanter power supply is turned on by the second power supply.

[0060] When the second bypass switch, the shield door contactor, and the high-voltage switch are all closed, the ion implanter power supply control circuit is turned on, energizing the coil. When the coil is energized, the contacts in the relay connect, thereby maintaining the ion implanter power supply control circuit on, powering the ion implanter. In actual applications, the high-voltage start switch typically pops open after closing, meaning the high-voltage start switch remains closed for a short period of time, such as 1 second or 500 milliseconds. After the high-voltage start switch closes, the coil is energized, connecting the contacts in the relay. Even if the high-voltage start switch pops open after closing for a short time, the ion implanter power supply control circuit remains on, powering the ion implanter.

[0061] In one possible embodiment, the ion implanter power supply control circuit may further include a high-voltage indicator light configured to display the on / off status of the high-voltage switch according to a preset display rule. As a possible implementation, different color indicators or different frequencies may be provided for different states of the high-voltage switch.

[0062] The above-mentioned high-voltage indicator light is connected in series with the second bypass switch, the shield door contactor and the high-voltage switch, and in parallel with the above-mentioned relay coil. When the power supply control circuit of the ion implanter is turned on, the high-voltage indicator light is displayed according to the preset rules to indicate the closed state of the high-voltage switch.

[0063] like Figure 3 As shown, Figure 3 A schematic diagram of a structure of an ion implanter power supply control circuit provided by an embodiment of the present invention, wherein the ion implanter power supply control circuit is applied to a power distribution box power supply control circuit. Figure 3 As shown in the upper middle circuit, it includes an air supply path and an electric supply path, wherein the air supply path includes an air source, an air valve, and an electromagnetic valve SGM PD interlocks, and the electric supply path includes a first power supply +24VDC, a shielding door contactor doors lock, and a first bypass switch. The contacts corresponding to the above-mentioned shielding door contactor are contacts 73 and contact 74.

[0064] In the power supply control circuit, the air valve opens, allowing air to flow from the source into the air supply passage. When the solenoid valve (SGM) PD interlocks detect compressed air, they energize, opening the air supply passageway and delivering air to the SGM distribution box to cool the distribution box. When the air supply passageway is open, the solenoid valve energizes. When the first bypass switch is closed or the shield door contactor is engaged, the power supply passageway is opened. This power supply passage delivers electrical energy to the 24V RTN circuit, which includes the distribution box and the electronic devices that draw power from it.

[0065] The above ion implanter power supply control circuit is as follows Figure 3 The circuit in the lower center section includes a second bypass switch S1-A, the doors lock contactor (corresponding to contacts 43 and 44), a high-voltage on-switch HV on, a relay contact pair K1B, a high-voltage off-switch HV off, and a high-voltage indicator light. Relay contact pair K1B is associated with the state of coil K1A. The second bypass switch S1-A, the doors lock contactor, the high-voltage on-switch HV on, the high-voltage off-switch HV off, and the high-voltage indicator light DSI are connected in series. Relay K1B is connected in parallel with the high-voltage on-switch HV on. Relay coil K1A is connected in parallel with the high-voltage indicator light and in series with the second bypass switch S1-A, the doors lock contactor, the high-voltage on-switch HV on, relay K1B, and the high-voltage off-switch HV off.

[0066] The above-mentioned second bypass switch and the first bypass switch are in reverse phase. When the first bypass switch is disconnected, the second bypass switch is closed. In this way, when the high-voltage start switch is closed and the high-voltage shutdown switch is closed, the ion implanter power supply control circuit is turned on, the coil and the high-voltage indicator light are energized, and when the coil is energized, the relay K1B is energized. In this way, after the high-voltage start switch pops open, the ion implanter power supply control circuit is still turned on until the high-voltage shutdown switch is disconnected.

[0067] When the embodiment of the present invention is applied, if the switch is damaged or becomes normally closed, a chain circuit will be triggered, and the ion implanter will be unable to work until the staff finds and solves the problem.

[0068] Based on the same inventive concept, an embodiment of the present invention also provides a power supply control method for an ion implanter, the method being applied to a power supply control circuit of a distribution box, the power supply control circuit of the distribution box comprising a first power supply, a first bypass switch and a shielding door contactor, the first bypass switch being connected in parallel with the shielding door contactor; when the first bypass switch and / or the shielding door contactor are closed, the first power supply is used to control the power supply of the distribution box. Figure 4 As shown, the method includes:

[0069] S401: When detecting that the first bypass switch is closed, control the second bypass switch to be open;

[0070] S402: When detecting that the first bypass switch is disconnected, controlling the second bypass switch to be closed, and detecting whether the shield door contactor is engaged;

[0071] S403 : When the shield door contactor is closed, the ion implanter is powered by a second power supply, where the second power supply is a power supply for controlling the operation of a high-voltage power supply of the ion implanter.

[0072] In a possible embodiment, the method further includes:

[0073] detecting whether a high-voltage switch is closed, the high-voltage switch being connected in series with the second power supply, the second bypass switch, and the shield door contactor;

[0074] When the second bypass switch is closed, the shield door contactor is engaged, and the high-voltage switch is closed, the second power supply is used to supply power to the ion implanter.

The memory stores a computer program executable by the at least one processor, wherein the computer program, when executed by the at least one processor, causes the electronic device to perform a method according to an embodiment of the present invention.
