  In the microscopic realm of semiconductor wet processing, every cleaning cycle, every etching step, and every photoresist stripping operation constitutes a critical battle determining chip performance and yield rates. At the heart of these processes lies the secure, precise, and contamination-free delivery of high-purity chemical solutions to the wafer surface. Huaxin Semiconductor's chemical diaphragm pumps serve as the ‘pure heart’ engineered for this purpose. With their exceptional materials and reliable design, they are deeply integrated into various wet processing equipment, becoming indispensable core components that safeguard process success.

  I. Within Chemical Delivery Systems (CDS): Guardian of High-Purity Chemicals

  The central chemical delivery system (CDS) in modern fabs functions as the ‘artery’ of the entire wet processing area, continuously supplying diverse chemicals to multiple devices.

  Application Scenario: Serves as the core delivery unit within CDS systems.

  Value Proposition:

  Ultra-pure fluoropolymer materials eliminate secondary contamination: All pump components in contact with chemicals are crafted from ultra-pure fluoropolymer materials. Their exceptionally low metal ion and particle leaching characteristics ensure chemicals maintain supreme purity from source to endpoint, perfectly meeting the stringent impurity control demands of high-end chip manufacturing.

  Comprehensive corrosion resistance, fearless operation: Whether handling acidic, alkaline, or solvent-based solutions, fluoropolymer materials' inherent robust chemical corrosion resistance effortlessly accommodates all, significantly enhancing system reliability and service life while reducing maintenance costs.

  II. Within Single-Wafer Cleaning/Etching Equipment: The Steady Arm for Precision Processes

  Single-wafer processing equipment demands exceptional process uniformity and repeatability, posing extreme challenges to the instantaneous stability and cleanliness of chemical delivery.

  Application Scenario: Integrated within single-wafer cleaners and etchers, it precisely supplies chemicals to spray arms or processing chambers.

  Value Proposition:

  Contamination-free transfer safeguards device performance: During pre-deposition cleaning, even trace metal contamination may cause device failure. Huaxin diaphragm pumps' ultra-pure characteristics ensure no new impurities are introduced during solution transfer, laying a solid foundation for subsequent high-quality film deposition.

  Stable supply, enhanced uniformity: Steady delivery capacity ensures chemicals cover the wafer surface with consistent flow and pressure, achieving uniform cleaning or etching results that directly improve overall wafer yield.

  III. Within Batch Wet Processing Equipment: The Reliable Engine Driving Efficient Production

  In tank-based equipment used for processes such as photoresist stripping and post-etch cleaning, pumps must operate continuously for extended periods, demanding exceptional durability and consistency.

  Application Scenario: Employed in conventional batch wet processing equipment for circulation, filtration, and chemical exchange.

  Value Proposition:

  Robust Durability for Uninterrupted Production: Featuring an aluminium alloy housing with multi-layer oxygen-resistant coating, it enhances structural integrity for sustained operation while effectively resisting corrosion from internal chemical atmospheres, ensuring uninterrupted production cycles.

  High Consistency, Ensuring Batch-to-Batch Stability: Manufactured in Class 100 and Class 10,000 cleanrooms, Huaxin diaphragm pumps exhibit exceptional product consistency. This guarantees identical performance across multiple units within a single facility or throughout an entire plant, ensuring stable and reliable process outcomes for every batch of wafers.
