Description

Technical Field

[0001] The utility model relates to the technical field of chip storage, in particular to a chip storage cabinet. Background Art

[0002] A semiconductor chip is a device that performs a specific function by etching and wiring a semiconductor wafer. These chips are not limited to silicon chips; other common materials include gallium arsenide and germanium. Existing semiconductor storage typically relies on nitrogen injection to prevent oxidation of the copper foil and pins on the wafer. However, nitrogen injection requires time to fully coat the wafer, and storage relies on large volumes of gas injection, which requires a long preparation time. Furthermore, some existing semiconductor chip storage boxes have simple structures and fail to effectively protect the semiconductor chips.

[0003] In order to solve the above problems, after searching, the existing published patent (application number: CN202323324885.4) is a low-temperature storage device for semiconductor chips. The article proposes "a box body is provided inside, and a nitrogen exhaust box is fixedly provided on the upper end face of the box body. The upper end face of the nitrogen exhaust box is connected to the external nitrogen box. The utility model completely covers the chip storage rack with the chip mounting rack. When the air on the lower end face of the chip mounting rack is completely discharged through the stopper, the stopper is closed, so that the semiconductor can be stored in nitrogen. The elastic layer around it can greatly reduce the vibration of the sliding rack and the semiconductor chip caused by external factors, thereby improving the protection capability of the semiconductor chip. The chip mounting rack can also perform secondary limit protection on the semiconductor chip to prevent the semiconductor chip from falling into the storage cavity, thereby enabling the utility model to protect the semiconductor chip for a long time with high safety."

[0004] Although the internal chips can be well protected, when the chips need to be taken out, due to the low temperature of nitrogen, directly opening the box door to take them out will harm the staff. In addition, although the above-mentioned document can discharge the internal nitrogen, the discharge speed is slow, and it takes a long time to discharge the internal nitrogen and take out the chips.
