HBM Wafer Contamination and Importance of Cleaning
Optimizing High Bandwidth Memory
Optimizing High Bandwidth Memory (HBM) wafer surface treatment is essential for improving bonding strength, surface cleanliness, and interface quality in advanced semiconductor packaging. Techniques such as plasma treatment, chemical cleaning, and surface activation help reduce contamination, enhance wafer bonding, and support reliable 3D die stacking. Effective HBM wafer surface treatment improves manufacturing yield, package reliability, and performance for AI accelerators, GPUs, and high-performance computing applications.
Water & Solvent Based Package Cleaning
ZESTRON offers water and solvent-based cleaning agents designed explicitly for packages such as flip chips, CMOS, and BGAs. These products are formulated for removing flux residues after pre-balling, i.e., the solder bump reflow process, from the tight spaces and capillaries between the chip and base materials.
Our cleaning processes ensure that CMOS sensors are free of streaks and particles, guaranteeing flawless image resolution. With the complete removal of flux residues and particles, optimal wetting of the underfill materials can be guaranteed.
