Description

This invention relates to a glass bottle cover assembly, and more particularly to a cover assembly for protecting glass bottles containing chemicals used in semiconductor processes. Glass bottles, widely used in daily life, are utilized in various ways depending on the characteristics and purpose of their contents. The photoresist (photosensitive liquid) containers used in semiconductor photoprocessing are made of special materials, including UV (ultraviolet) blocking paint that utilizes the principle of light refraction. This is to protect the special properties of the solution. The solution itself is expensive and, if leaked, is harmful to human health, so it is generally stored in complete isolation. The container size is typically 1 gallon (3.8 liters), and its volume and shape are standardized. Due to the nature of the solvent, its photosensitivity is sensitive to external temperature, and it must be stored in a facility with a constant temperature of 23 degrees Celsius (the typical storage temperature is below 4 degrees Celsius). In practice, due to concerns about harm to human health from cracks caused by careless handling, it is classified as a hazardous material and its handling is restricted to authorized personnel only. Furthermore, there is currently a growing concern for the environment and safety. Therefore, if toxic substances leak due to the breakage of glass bottles containing chemicals, it could first harm the health of workers and negatively impact the semiconductor company's public image. This creates a very real need to proactively prepare countermeasures. The goal is to improve the problems of conventional glass bottles by replacing them with plastic materials. However, since the purity of chemical solutions cannot be completely maintained through dissolution when using plastic containers, the use of glass bottles is expected to continue for a considerable period. Patent Document 1: Korean Patent Registration No. 10-2071399, a protective device patent, relates to a device for protecting photoresist bottles used in semiconductor photoprocessing, and includes a protective method for enclosing the outside of the bottle. However, for actual use in photoprocessing, it is necessary to remove the protective device and expose the bottle to the outside. Patent Document 2: Korean Patent Registration No. 10-1746779 is a patent relating to a cover assembly for protecting chemical bottles, and the cover assembly is manufactured based on a glass bottle with a handle. With the cover assembly attached, the container lid is broken through the virgin ring, the cap of the chemical container is opened, and the chemical substance inside is used. Here, the process of placing the chemical substance into the chemical container, covering it again with the cover assembly, and then transporting it is necessary. There is also a risk of damage during the transport process when covering the chemical container with the cover assembly. The added process consolidates substantial risks, which could lead to problems with the effectiveness of using the cover assembly.
