With the rapid development of high-tech industries such as semiconductors, photovoltaics and optics, the requirements for the surface cleanliness of materials are becoming increasingly strict. As the core basic material in these fields, the cleaning quality of glass silicon wafers is directly related to the product performance and the yield rate. Against this backdrop, the Weigute glass silicon wafer ultrasonic cleaning machine has emerged as a rising star in the field of precision cleaning, thanks to its innovative technical design and highly efficient cleaning capabilities. This article will analyze the industry value of this device from four dimensions: technical principles, application scenarios, product advantages, and market value.


I. Scientific Breakthroughs in Ultrasonic Cleaning Technology

The core technology of Weigute ultrasonic cleaning machines is based on the high-frequency cavitation effect. The equipment converts electrical energy into high-frequency mechanical vibration (typically 20-100 KHZ) through piezoelectric ceramic transducers, forming tens of thousands of micron-sized bubbles in the cleaning solution. Under the effect of sound pressure, these bubbles rapidly expand and implod, releasing an instantaneous high temperature of up to 5000℃ and a shock wave of 5000 ATM, which can instantly remove nanoscale contaminants on the surface of silicon wafers, including fine dust particles, organic residues, metal ions, etc.

Compared with traditional spray or chemical immersion cleaning, this technology has significant advantages:

Non-contact cleaning:
Avoids scratches on the silicon wafer surface caused by mechanical friction;

Three-dimensional penetration: It can penetrate deep into the interior of complex structures such as micro-pores and crevices.

Environmental protection and energy conservation: Reduce the usage of chemical solvents by more than 70%.


Ii. Scene adaptability of precision manufacturing

This equipment has been specially optimized for the characteristics of glass silicon wafers and has demonstrated outstanding performance in multiple key areas:

Photovoltaic industry:
Cleaning of monocrystalline/polycrystalline silicon wafers after fluxing to remove acid erosion residues and improve battery conversion efficiency by 0.3-0.5%.

Semiconductor wafers: Photoresist removal in the previous process, with cleanliness reaching Class 1 standard;

Optical coating: Pre-treatment for lens coating, with the surface roughness controlled at Ra≤0.5nm;

MEMS devices: Micro-sensor structure cleaning, yield rate increased to 99.8%;

The multi-band compound cleaning mode specially developed for large-sized silicon wafers (12 inches and above) can simultaneously handle contaminants of different particle sizes. The equipped TOC (Total organic Carbon) online monitoring system enables intelligent prediction of the cleaning solution's lifespan, reducing operating costs by 30%.


Iii. The Promoting Value of Industrial Upgrading

Under the background of "carbon neutrality", Weigute equipment drives industry transformation through three major innovations:


Process innovation: The traditional 6-step cleaning process has been simplified to 3 steps, increasing the production cycle by 40%.

Green manufacturing: By adopting a closed-loop water circulation system, wastewater discharge is reduced by 85%.


Intelligent transformation: Achieving digital twins through device interconnection and optimizing the combination of process parameters;


According to industry report statistics, the leading photovoltaic enterprises that adopt this equipment have reduced the cleaning cost of a single silicon wafer from 0.12 yuan to 0.07 yuan. Calculated at an annual production capacity of 10GW, the annual cost savings exceed 30 million yuan. In the semiconductor field, the improvement in cleanliness it has created has enabled the yield rate of 28nm process chips to exceed 98.6%, helping domestic chip manufacturing break through technical bottlenecks.

Conclusion: A new benchmark for precision cleaning

The Weigute glass silicon wafer ultrasonic cleaning machine is not merely a piece of equipment; it is also a solution provider in the era of precision manufacturing. Its technical system that integrates physical cleaning, intelligent control and green processes is redefining the standards of industrial cleaning. With the rise of emerging fields such as third-generation semiconductors and quantum chips, this model of driving industrial upgrading through technological innovation will continue to inject development momentum into high-end manufacturing.
