Background of the Invention: With the increase in integration of semiconductor components, the semiconductor manufacturing process is moving into the era of deep sub-micron components. Due to the shrinking of the line size of components, integrated circuit components are more seriously affected by pollutants. In other words, when the dust particles adhere to the wafer on which the semiconductor device is made, it may affect the pattern of the precise wire layout on the wafer, and cause serious consequences of the electrical short circuit or disconnection of the device. Therefore, in the manufacturing process of high-density semiconductor components, the requirements for cleanliness are extremely strict. Particles or gaseous pollutants will contaminate the wafer, resulting in a decrease in product yield and a reduction in output value. However, due to the increasing complexity of semiconductor devices, the complexity of process steps has also increased. There are many possible causes of contamination in the production process of semiconductor components, such as contamination of the reaction chamber or wafer due to poor quality of the gas pipelines, insufficient purity of the supplied thoron, vacuum accessories, wide or poor pressure gauges.

During the production of semiconductor components, there are various opportunities for different purposes of the process. Therefore, the wafer may need to be converted in different process equipment to manufacture the required components. When the wafer is transferred between the equipment, the wafer is first placed in a wafer box, and then automated material processing is used. The system (Automated Material Handling System; AMHS) transports the wafer box to the next process machine, and then uses the robotic arm to remove the wafer to facilitate the next process step, or the wafer box is stored first. Put it in the clean room storage and wait for the next process step. However, the material of the wafer box is usually acrylic, so it is quite easy to change the wafer box during the transportation or handling of the wafer box. The friction with the outside world will cause static electricity (Static Electricity) to generate static electricity. When the wafer cassette is charged with static electricity, it is likely to adsorb the particles existing in the clean room or the staff, which will cause a large amount of The particles are attached to it, especially the bottom of the wafer box that is in frequent contact with other devices. In subsequent processes, the wafer box will be transported to the different process machines by the automated material processing system or to the warehouse. And the process machine or storage is contaminated with particles, and when the robotic arm takes out the wafer placed in the wafer box, the wafer may be contaminated with particles because of the air flow or the robotic arm is contaminated with particles. , And then destroy the component layout pattern on the wafer, which seriously affects the electrical stability of the component.

Description of the invention (Contents. Then, the exhaust port Π 8 located at the upper end of the reaction chamber Π 2 will contain particles and dust. The exhaust gas 126 waiting for pollutants is extracted from the reaction chamber 112. When the robotic arm 4 transports the wafer cassette 110 to the exit 130 of the reaction chamber 112, the sensor 120 located at the exit 130 of the reaction chamber 112 will sense the wafer cassette 11 0, and the air inlet device of the cleaning device 108 is closed, thereby stopping the ejection of the working gas 124 from the air inlet 116, thereby completing the cleaning step of the wafer cassette 110. Because the sensor 120 can sense that the wafer cassette 1 1 0 enters Or leave the reaction chamber 112, and start or shut off the air intake device of the cleaning device 108, and automatically eject the action gas 124 or stop the action gas 1 24 from the air inlet 116 at the lower end of the reaction chamber 112. Therefore, in the present invention, Wafer In the cleaning method of 110, the entire cleaning process does not need to be operated by a worker, and does not increase the burden on the online staff. In addition, if the static electricity carried by the wafer cassette 1 10 is too large, so that The wafer box 110 has a large adsorption force for particles, dust and other pollutants, resulting in the strength of the airflow formed by the action gas 124 ejected from the cleaning device 108 cannot blow particles, dust and other pollutants from the surface of the wafer box 110 At this time, a static elimination device 122 can be installed near the entrance 128 of the reaction chamber 112. In this way, when the wafer cassette Π 0 enters the reaction chamber 112, it can be used for 10 paper sizes in China. National Standard (CNS) A4 (210 X 297 mm) nm H * ϋ H ϋ el ·!
