Problems solved by technology

[0003] In the semiconductor process, whether it is a vapor deposition process, an etching process or an ion implantation process, various gases are required to allow the reaction to proceed. These gases are usually stored in various steel cylinders, and the cylinders are placed in specific storage The location is preserved, and the steel cylinders containing the gas are transported to the silicon wafer factory for use in different processes when used. However, because these gases are usually highly toxic (such as PH3, EF3 and ASH3) or explosive (such as SiH4, H2 ), so it must be handled very carefully. Wafer factories usually store these gases in specific gas storage cabinets, and cooperate with pressure regulators, gas detectors, gas removal devices, etc. to prevent gas leakage. However, when the gas storage cabinet When the gas in the cylinder is used up, the gas must be transported to the gas storage cabinet in the form of steel cylinders for replenishment. Usually, the steel cylinders are moved manually, but this is very easy to cause disasters due to human negligence and gas leakage in the cylinders, and every time The quantity shipped is limited and the shipping efficiency is low

Embodiment Construction

[0044] The structural features of the present invention and the beneficial effects achieved are further described below in conjunction with the accompanying drawings and embodiments.

[0045] The present invention is a design of a steel cylinder trolley, and its main function is to enhance the safety of transporting steel cylinders containing dangerous gases. Since most of the gases used in the semiconductor process are toxic, traditional manual transportation or general carts Transportation may be dangerous due to improper operation or human negligence. Therefore, the unique cart design of the present invention can provide airtight protection for the steel cylinders. In case the toxic gas in the steel cylinders leaks, it will not spread into the air and cause Danger.

[0046] First, the schematic diagram of the three-dimensional structure of the present invention is as follows figure 1 As shown, the cylinder trolley mainly includes a trolley main body 10, which is provided ...

Abstract

The present invention provides a cylinder carriage, it has the gas-tight funtion and can be used for transferring cylinder in which the dangerous gas is held, when the cylinder gas is leaked, its gas-tight space can make the gas can not be diffused into air and do not produce harm to human body. Said cylinder carriage mainly comprises a carriage main body whose interior has a containing space with double-layer structure. On the carriage main body is set a gas monitoring system including gas detector, pressure gauge and sensor, etc.

Description

[0001] technical field [0002] The invention relates to a design of a trolley, in particular to a steel cylinder trolley used for transporting and temporarily storing dangerous gases. Background technique [0003] In the semiconductor process, whether it is a vapor deposition process, an etching process or an ion implantation process, various gases are required to allow the reaction to proceed. These gases are usually stored in various steel cylinders, and the cylinders are placed in specific storage The location is preserved, and the steel cylinders containing the gas are transported to the silicon wafer factory for use in different processes when used. However, because these gases are usually highly toxic (such as PH3, EF3 and ASH3) or explosive (such as SiH4, H2 ), so it must be handled very carefully. Wafer factories usually store these gases in specific gas storage cabinets, and cooperate with pressure regulators, gas detectors, gas removal devices, etc. to prevent gas ...
