High-Precision Metering Pumps for Semiconductor and Perovskite Applications: FSH-EBP Series by Guangzhou Ascend
3 min readIn advanced manufacturing industries such as semiconductors and perovskite photovoltaics, precision fluid delivery plays a critical role in determining product quality and process stability. Applications like photoresist coating and perovskite slurry dispensing require extremely stable, accurate, and contamination-free fluid control systems.
Traditionally, Japanese metering pumps from manufacturers such as KOGANEI and IWAKI have been widely used in high-end precision fluid applications. However, global supply chain uncertainty, procurement delays, and after-sales support limitations have increasingly become concerns for production continuity in semiconductor and photovoltaic industries.
Against this backdrop, Guangzhou Ascend Precision Machinery Co., Ltd has developed the FSH-EBP series high-precision metering pumps, designed to support stable and controllable fluid delivery solutions for domestic high-end manufacturing.
FSH-EBP Series Overview
The FSH-EBP series is designed for precision fluid control scenarios such as semiconductor photoresist coating and perovskite material processing. It focuses on stability, repeatability, and process compatibility in demanding production environments.
1. High Precision and Stable Repeatability
The FSH-EBP series is engineered to support high-precision coating processes where consistency is critical.
Key performance features include:
-
Discharge repeatability within ±1%
-
Micro-dispensing capability down to 1μL
-
Stable, pulse-free delivery output
-
Consistent pressure control during operation
These features help reduce variation in coating thickness and improve process uniformity across substrates.
2. Wide Fluid Compatibility and Process Flexibility
The system is designed to handle a variety of process fluids used in semiconductor and photovoltaic manufacturing.
It supports:
-
Viscosity range: 0–300 cP
-
Adjustable flow control from micro to standard dispensing levels
-
Flexible operation for both R&D and mass production environments
This allows adaptation to different production requirements without major system changes.
3. Cleanliness and Chemical Resistance Design
To meet semiconductor-grade cleanliness requirements, the FSH-EBP series is built with high-purity and corrosion-resistant materials.
Design features include:
-
Wetted parts made of SUS316, PTFE, and PFA
-
Smooth internal flow channels to reduce particle generation
-
Minimal dead volume structure for stable fluid delivery
-
Chemical resistance for photoresist and related solvents
These characteristics help maintain fluid purity and reduce contamination risks in sensitive processes.
4. Applications in Semiconductor and Perovskite Processes
Photoresist Dispensing
In semiconductor lithography processes, the pump is used to deliver photoresist onto substrates before spin coating. Stable micro-dispensing helps improve coating uniformity and reduces material waste.
Perovskite Solar Cell Processing
In perovskite photovoltaic manufacturing, the system supports stable slurry delivery for coating and printing processes, helping ensure uniform film formation and improved process consistency.
5. Supply Chain Stability and Domestic Alternative Value
One of the key considerations for manufacturers is supply chain reliability.
Compared with imported equipment, the FSH-EBP series is designed to offer:
-
More stable supply availability
-
Faster technical and service response
-
Reduced procurement lead time
-
Lower long-term maintenance complexity
-
Easier integration into existing production lines
In many cases, it can be used as a functional replacement for imported pump systems with minimal process adjustment.
6. Company Background
With nearly 20 years of experience in precision fluid control, Guangzhou Ascend Precision Machinery Co., Ltd has provided solutions for multiple advanced manufacturing sectors, including lithium battery production, semiconductors, and photovoltaic applications.
The FSH-EBP series represents one of its core product lines focused on high-precision dispensing applications, and has been applied in industrial production environments where process stability and repeatability are critical.
Conclusion
As semiconductor and perovskite manufacturing continue to evolve toward higher precision and tighter process control, high-performance metering pumps play an increasingly important role in ensuring production stability.
The FSH-EBP series provides a precision-focused fluid control solution designed to meet these requirements, offering an alternative approach to traditional imported systems while supporting stable and scalable manufacturing processes.
