[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] This embodiment provides a low-temperature adhesive removal device, such as... Figures 1 to 9 As shown, the device includes a body 1 and a blocking assembly 2. The body 1 has a process chamber 11 and an inlet 12 and an outlet 13 connected to the process chamber 11. The inlet 12 and the outlet 13 are arranged opposite to each other. Process gas is adapted to flow into the process chamber 11 through the inlet 12 and to flow out of the process chamber 11 through the outlet 13. The blocking assembly 2 is disposed in the process chamber 11 and between the inlet 12 and the outlet 13 to divide the process chamber 11 into a working chamber 111 and an outlet chamber 112. The blocking assembly 2 has a plurality of connecting parts 211, any one of which connects the working chamber 111 and the outlet chamber 112. The inlet 12 is connected to the working chamber 111, and the outlet 13 is connected to the outlet chamber 112. The working chamber 111 is suitable for placing a workpiece to be processed. The blocking assembly 2 is adapted to block the flow of process gas. When the process gas flows from the working chamber 111 to the outlet chamber 112, the blocking assembly 2 blocks the flow of process gas and allows the process gas to flow into the outlet chamber 112 through all the connecting parts 211.

[0043] The low-temperature adhesive removing device has the blocking assembly 2 arranged in the body 1. The body 1 has the process cavity 11, the inlet 12 and the outlet 13 arranged in communication with the process cavity 11. The inlet 12 and the outlet 13 are oppositely arranged. The process gas can flow into the process cavity 11 through the inlet 12 and flow out of the process cavity 11 through the outlet 13. The blocking assembly 2 is arranged in the process cavity 11 and between the inlet 12 and the outlet 13. The process cavity 11 is divided into the working cavity 111 and the outflow cavity 112. The inlet 12 is in communication with the working cavity 111. The outlet 13 is in communication with the outflow cavity 112. The blocking assembly 2 is provided with a plurality of communication portions 211. Each communication portion 211 can communicate the working cavity 111 and the outflow cavity 112. Therefore, the process gas flowing into the working cavity 111 through the inlet 12 can flow into the outflow cavity 112 from the working cavity 111 through the communication portion 211 of the blocking assembly 2 and then flow out of the outflow cavity 112 through the outlet 13.

[0044] In addition, the workpiece can be placed in the working cavity 111. When the process gas flows into the working cavity 111 through the inlet 12, the process gas can contact the surface of the workpiece to process the workpiece. Due to the blocking of the blocking assembly 2, most of the process gas is accumulated in the working cavity 111 and a small part of the process gas flows into the outflow cavity 112 through the communication portion 211. The process gas in the working cavity 111 is uniformly distributed. The amount of the process gas distributed on the surface of the workpiece is uniform. The processing uniformity of the surface of the workpiece is improved.

[0045] The low-temperature adhesive removing device provided by the embodiment has the following advantages: Figures 3 to 6 As shown in the figure, the blocking assembly 2 includes the blocking piece 21 and the flow guide piece 22. The flow guide piece 22 is arranged on the blocking piece 21 and in the outflow cavity 112.

[0046] The low-temperature adhesive removing device has the blocking component 2 including the blocking piece 21 and the flow guide piece 22, the blocking piece 21 is arranged in the process cavity 11 and between the inlet 12 and the outlet 13, and the flow guide piece 22 is arranged on the blocking piece 21 and in the flow-out cavity 112, all the communication portions 211 are arranged on the blocking piece 21 corresponding to the flow guide piece 22, and the flow guide piece 22 is provided with a plurality of flow guide portions 221, the flow guide portions 221 are flow guide holes in the embodiment, and each flow guide portion 221 is communicated with a corresponding communication portion 211, so that the process gas can flow into the flow-out cavity 112 through the flow guide portions 221 after flowing into the communication portions 211 from the working cavity 111.

[0047] In addition, the axis of the communication portion 211 is perpendicular to the axis of the flow guide portion 221, so that the flow time of the process gas is increased when the process gas flows into the flow guide portion 221 from the communication portion 211 and flows into the flow-out cavity 112 through the flow guide portion 221, and the flow guide portion 221 can also provide a blocking effect for the process gas to avoid the process gas flowing directly to the outlet through the communication portion 211, so that a larger part of the process gas flowing into the working cavity 111 through the inlet 12 can be accumulated in the working cavity 111, which is beneficial to further improve the uniformity of the process gas in the working cavity 111; at the same time, the opening positions of the communication portion 211 and the flow guide portion 221 are chamfered, and the connection positions of the communication portion 211 and the flow guide portion 221 are rounded, so as to avoid the gas flowing into the communication portion 211 directly impacting the sharp edge and rebounding, thereby improving the flow efficiency of the process gas.

[0051] The low-temperature adhesive removal device has the guide 4 disposed in the working cavity 111, and the guide 4 is a guide ring in this embodiment and is disposed between the ionizing member 3 and the blocking member 21, so that after the ionizing member 3 ionizes the process gas into plasma, the guide 4 can guide the plasma to the blocking member 21, thereby avoiding the plasma flowing everywhere in the working cavity 111 and affecting the processing efficiency of the workpiece.

[0052] The low-temperature adhesive removal device provided in this embodiment has the following advantages.

Figure 1 As shown, the low-temperature adhesive removal device further comprises a power supply member 6 disposed on the body 1, and under the action of electricity, the power supply member 6 is adapted to provide a bias voltage to the workpiece in the working cavity 111.

[0055] The low-temperature adhesive removal device has the power supply member 6 disposed on the body 1, and the power supply member 6 is a bias power supply in this embodiment, and since the body 1 and the cooling member 5 are both made of aluminum, the power supply member 6 can generate an electric current on the body 1 under the action of electricity, thereby generating an electromagnetic field in the working cavity 111 and forming an electromagnetic field perpendicular to the surface of the cooling member 5 on the surface of the cooling member 5 to apply a bias voltage to the workpiece, and at the same time, the electromagnetic field can ionize the workpiece placed on the cooling member 5 in the working cavity 111, so that the workpiece can obtain better molecular activity, thereby accelerating the etching reaction of the workpiece with the plasma and facilitating the further improvement of the etching efficiency of the workpiece.
