Multi-gas and span adjustment functions
Choose one device platform to meet the needs of different gases and flow ranges, store and pre-set multiple gas calibration information, users only need one device to easily switch between different gases and ranges and reduce inventory, through software or PLC can be implemented without disconnecting the instrumentation from the system.
Aplication of EDC-500 Massflow Controller and Metes
Epitaxial Process System
The epitaxial process refers to the process of growing a fully aligned single crystal layer on a substrate. In the manufacture of integrated circuits, the commonly used epitaxy method is vapor phase epitaxy. During the epitaxy process, the gas flow into the reaction chamber needs to be precisely controlled. MFC can be equipped on the gas supply line. By adjusting the control parameters of MFC (such as current or pressure), precise control of gas flow can be achieved to ensure stable and accurate gas flow required in the epitaxy process.
Photovoltaic Industry
A certain amount of gas needs to be supplied during the preparation of solar cells, such as precursor gas and protective gas used to prepare thin films. MFC can be used to control the flow of these gases to ensure the stability and repeatability of the solar cell fabrication process. Flow devices are used in the application layer of crystalline silicon wafers for conventional silicon-based solar cells, as well as in the fabrication of thin layers on flexible substrates as second-generation amorphous silicon-based thin-film solar cell components.
Vapor Deposition System
Vapor deposition is a commonly used thin film preparation technology. The gas precursor is sent into the reaction chamber, and the gas precursor is deposited on the surface of the substrate to form a thin film through a chemical reaction or physical process. MFC can accurately control the gas flow during the vapor deposition process according to the preset gas flow to ensure the stability of gas concentration and flow in the reaction chamber. Biosflow is the professional manufacturer of EDC-500 series of Massflow Controller.
