Microwave PLASMA
Microwave Plasma Helps Semiconductor Packaging Process
With the continuous development of technology, the requirements for semiconductor packaging are getting higher and higher, and microwave plasma cleaning, which improves the packaging quality, has become an indispensable process. The purpose of cleaning is to thoroughly remove particles, organic and inorganic impurities from the surface of the equipment to ensure product quality.At present, plasma cleaning technology has been highly valued and widely recognized by the society due to its outstanding advantages.
①Pre-treatment of die bonding
Removing material surface contaminants and oxides facilitates solder reflow, improves chip-to-carrier connection, reduces peeling, and improves heat dissipation performance.
②Pretreatment of metal bonding
Removes organic contaminants from metal pads, removes thin contamination surfaces, and improves bond strength and bond wire pull uniformity.
③Removal of photoresist
Remove residual photoresist and other organics, activate and roughen wafer surface, and improve wafer surface wettability.
④Pretreatment before plastic sealing
Remove the contaminants on the surface of the material, make the chip surface and the plastic packaging material firmly bonded, and reduce the generation of defects such as delamination and air bubbles.
