SPV-24M Microwave On-Line Vacuum Plasma Cleaner is an overall solution for MW PLASMA processing and performance testing designed for the semiconductor industry. It is an ideal choice for cleaning, activation, degumming, and etching.
working principle
Microwave plasma cleaning is a process in which plasma is used to chemically or physically treat the surface of the workpiece at the molecular level to remove contamination and improve surface performance. Corresponding to different pollutants, different cleaning processes should be used. When the pressure in the cavity is in dynamic equilibrium, the high-frequency alternating electromagnetic field generated by the oscillation of the microwave source ionizes the process gases such as argon, oxygen, nitrogen, and hydrogen to generate plasma, and the active plasma carries out physical bombardment and chemical bombardment of the cleaned objects. Redox reactions. The structure of the microwave plasma cleaning machine is mainly divided into four major components: control system, vacuum chamber, process gas system, and metal hollow conduit.
Industry-specific solutions
Semiconductor industry application Die attach pretreatment:Remove contaminants on the surface of materials, increase surface wettability, improve colloid fluidity, and ensure binding ability with other materials. Before plastic sealing:Remove contaminants on the surface of the material, so that the surface of the chip and the plastic packaging material are firmly combined, and the occurrence of delamination and air bubbles is reduced.
Metal bonding pretreatment:Removes organic contamination from metal pads, improving the strength and reliability of the soldering process.
photoresist removal：Remove residual photoresist and other organics, activate and roughen wafer surface, and improve wafer surface wettability.
