CMP Filtering
In the CMP process of "strategist competition", for the flattening treatment of silicon wafer or other substrate materials, it is necessary to filter the products with large particle diameter, retain the effective working particles for grinding, and achieve the optimal hydrodynamic state. Hangzhou Dali's filter element has excellent particle retention performance and improves customers' production cost-effectiveness.
Lithography Process
With the refinement requirements of processing line width, the cleaning control of products is more and more strict. The precipitation requirements of various pollutants and metal ions put forward higher requirements for the production of filter element. Dali filtration provides high cleanliness products for process upgrading and ensures product quality.
Hvac System
The plant system needs to provide a stable supply of clean chemicals, ultrapure water, and clean process gases throughout the FAB. This puts forward highrequirements fo the stability and consistency of the filterelement used in each section. Hangzhou kinda large flow filter element, security filter element, high precision folding filterelemenl and perfluorinated filter element series provide stable filtration service for factory management system
Process Technology
In the manufacturing process of flat panel display, the performance of filter products directly affects the quality and yield of finished products. Especially in the high generation line, the problem of filter products will cause large quantities of scrap and loss. Hangzhou Dali filter provides customers with stable and reliable products according to the requirements of each process, analyzes and solves various process problems, optimizes products and reduces costs.
Electronic Chemicals
As the key material of semiconductor production, clean electronic chemicals play a key role in the semiconductor production process. Various electronic chemicals with different characteristics have different requirements for filter products, and have strict requirements for the cleanliness and low precipitation of filter products. Dali company uses advanced equipment and technology to strictly control the cleanliness of filter products and produce products with low precipitation and low metal ions.
Data Storage
In the digital information age, the storage medium has developed from paper carrier to a variety of new carrier storage media such as hard disk, flash memory, USB flash disk, SD card and so on. In order to manufacture portable and high-capacity data storage products, the equipment and process depend on the pollution control and filtration purification technology of each process. Hangzhou Dali develops and produces various advanced filtration products and related technologies to meet customers' personalized processes and needs.
