Abstract
Description
Technical Field
[0001] The utility model relates to a gas chamber, which belongs to a chemical integrated gas chamber. Background Art
[0002] In the manufacture of large-scale integrated circuits (ICs), a large amount of high-purity chemicals are required, such as RCA cleaning, wet etching, etc. With the continuous advancement of IC process technology, the requirements for particle control in the production and packaging of high-purity electronic-grade chemicals are becoming increasingly higher.
[0003] Integrated circuit (IC) manufacturing has become one of the most advanced and largest industries in the world. Photolithography technology plays a very important role in the production of ultra-large-scale integrated circuits (IC). In the manufacture of integrated circuits (IC), the geometric pattern on the mask master needs to be transferred to the photoresist film on the substrate surface first, and then the image on the photoresist film is copied to the substrate surface through a series of processing technologies from exposure to etching to form a permanent pattern. The typical micro-processing process includes substrate pretreatment, glue coating, pre-baking, exposure, development, cleaning, post-baking, etching, and degumming to obtain the desired permanent pattern. That is, before the graphic processing, the silicon wafer is first dried and processed, and then the photoresist is evenly coated. After pre-baking, the photoresist solvent is removed and the exposure circuit pattern is formed on the silicon wafer through step-down projection exposure. Then, after development, the exposed part is removed and the unexposed part is retained. After post-baking, the photoresist film is more firmly adhered. Then, wet etching is used to permanently retain the circuit pattern on the silicon wafer. Thermal diffusion and ion implantation are used for doping at the same time, and finally a stripper is used to remove the photoresist film to form a permanent IC design pattern on the silicon wafer.
[0004] In the process of manufacturing integrated circuits or semiconductor discrete devices, multiple or even dozens of photolithography processes are often required, and each photolithography process needs to complete the above process cycle. The technology of photoresist is complex and there are many varieties. The quality of the photoresist mixing, filtering and supply system directly affects the CMP process effect. Photoresist should not produce large particles, crystallization, photosensitivity and other problems during pre-mixing and use. In order to solve such problems, people have been seeking a more ideal technical solution for safe operation mode.
[0005] Most of the equipment in the domestic photoresist mixing and filtering supply system is imported. With the rapid development of the domestic semiconductor industry, the upstream fine chemical industry has also developed supporting equipment. In order to solve such problems, people have been looking for a more ideal technical solution that is both accurate and convenient.
[0006] With the continuous development of my country's semiconductor industry, there are more and more chemical varieties, and the domestic requirements for chemical supply processes and supply processes are becoming more and more stringent, and the precision is getting higher and higher. In the prior art, the switching of chemical modules usually needs to be carried out in the gas chamber, but due to the limited position of the gas chamber, the assembly of the chemical pipeline is inconvenient, which affects the assembly accuracy.
