Application and Technical Analysis of Fully Automatic Deposition Removal and Cleaning Machines in Semiconductor and Precision Manufacturing 

In modern semiconductor manufacturing, photonic component processing, and the production of precision electronic devices, the cleaning process holds a crucial position. Among them, removing residual adhesives, photoresists, or other surface adherents is the core step to ensure the high cleanliness of wafers, optical components, and electronic devices. Traditional manual or semi-automatic cleaning methods have problems such as low efficiency, uneven cleaning, and unstable operation. The fully automatic adhesive removal cleaning machine, through a highly automated cleaning process, achieves efficient removal of adhesive substances on the surface of the workpieces, ensuring process stability, product yield, and manufacturing safety.

II. Working Principle of the Fully Automatic De-greasing and Cleaning Machine

The core of the fully automatic de-greasing and cleaning machine is to achieve the complete removal of the adhesive layer on the surface of the workpiece through chemical, mechanical and physical processes. The typical process includes: 

Automatic loading/unloading

Wafers or workpieces are automatically loaded into the cleaning tank by means of a mechanical hand or a vacuum suction device, reducing the risk of human operation and improving production efficiency. 

Solution Distribution and Circulation

The cleaning solution (solvent, decoupling agent or surfactant) is uniformly distributed over the surface of the workpiece through the pump circulation system, achieving the dissolution of the adhesive layer and chemical removal. 

Temperature control and heating

The heating module regulates the temperature of the cleaning solution, ensuring that the chemical reaction achieves optimal results and accelerating the dissolution and removal of the adhesive. 

Ultrasound assistance (optional)

Some high-end devices are equipped with ultrasound functionality. Through the cavitation effect, it enhances the penetration power of the cleaning solution, removing residual glue and particles on the surface of microstructures. 

Mechanical stirring or spraying

The spraying or stirring system further enhances the contact between the cleaning solution and the surface of the workpiece, ensuring that the adhesive layer is completely dissolved. 

Drying treatment

Through centrifugal drying, nitrogen purging or hot air drying, residual liquid is prevented from remaining, ensuring that the workpiece surface is clean, dry and free of any marks. 

Waste liquid recycling and discharge

The waste liquid is filtered and recycled for processing, ensuring safe and environmentally friendly operations and reducing the waste of chemical reagents. 

The fully automatic degreasing and cleaning machine achieves the complete removal of adhesive substances through this series of automated processes, while ensuring that the surface of the workpiece is not damaged.

Liquid circulation system

The pump, pipelines, spray heads and filters form the circulation system, ensuring that the cleaning liquid is evenly distributed and continuously circulated, removing impurities and residual glue from the solution. 

Heating and temperature control module

Precisely control the temperature of the cleaning solution to enable the chemical reaction for decapsulation to proceed under specific conditions. 

Ultrasound-assisted system

The cavitation effect enhances the removal efficiency of tiny particles and complex structures, ensuring the cleanliness of the surface of micro-components. 

Drying system

Centrifugal spin-drying, hot air drying or nitrogen purging are used to ensure that the surface of the workpiece dries quickly and without any marks. 

Control system

The cleaning process is controlled by PLC or touch screen, enabling automatic management of liquid ratio, temperature, cycle time and drying mode.
