The semiconductor industry demands precision, reliability, and efficiency at every step of the manufacturing process. Cooling and media regulation are critical areas where precise control can significantly enhance productivity and product quality. By leveraging Dpstar’s collaboration with Festo, we provide advanced automation solutions tailored to the semiconductor manufacturing sector. Festo’s cutting-edge technology ensures manufacturers can maintain optimal performance, addressing the challenges of stable cooling circuits and efficient media regulation.

Cooling Circuit Control 

The Backbone of Semiconductor Manufacturing

In semiconductor manufacturing, the precise control of temperature is a key factor for maintaining production efficiency and ensuring product integrity. Cooling circuit control refers to the regulation of coolant flow and temperature within a closed-loop system, designed to remove excess heat from sensitive manufacturing equipment. Heat is generated in various processes, such as lithography, deposition, and etching, and if not properly managed, can cause equipment failures, product defects, and reduced yield.

What is Cooling Circuit Control?

Cooling circuit control is the automated management of cooling systems that use liquids or gases to maintain optimal temperatures in semiconductor equipment. It involves the precise adjustment of flow rates, pressures, and temperatures to remove excess heat while keeping the equipment and environment within defined parameters. These systems must work continuously, as temperature fluctuations, even by small degrees, can affect the delicate processes involved in semiconductor manufacturing.

The primary components of a cooling circuit system include:

Coolant Distribution Units 

Distribute coolant (deionized water or heat transfer fluids) to various equipment components.

Valves & Actuators

Control coolant flow and direction, ensuring optimal cooling for each section.

Heat Exchangers

Transfer heat from the equipment to the coolant and then remove it from the system.

Pumps

Circulate the coolant through the system at the required pressure and flow rate.

Sensors & Control Systems

Monitor temperature, flow, and pressure, adjusting the system for precise control.

How Does Cooling Circuit Control Work?

Cooling circuit control in semiconductor fabs operates in a closed-loop system that is continuously monitored and adjusted through automation. Here’s a simplified breakdown of how the process works:

Heat Generation

During semiconductor processing, various stages, like photolithography or plasma etching, generate significant heat, which must be quickly dissipated to prevent damage to both the equipment and the wafers.

Heat Removal

The cooling circuit draws heat away from the hot surfaces using a circulating coolant. The coolant absorbs the heat from the equipment or the chamber and transfers it to a heat exchanger.

Heat Exchange

The heat exchanger removes the heat from the coolant, either by transferring it to the ambient environment or through cooling towers. In semiconductor fabs, this is done with precision to avoid temperature spikes.

Temperature and Flow Control

Automated systems use sensors to constantly monitor the coolant’s temperature and flow rate. If the temperature deviates from the optimal range, valves and actuators adjust the flow or pressure to maintain balance. Real-time data from these sensors helps maintain consistent temperature regulation across the system.

Pressure Regulation

Proper pressure regulation ensures that coolant reaches all necessary points in the system. This ensures that coolant flows at the right pressure and volume without wastage or overload.

Return to the Source

The cooled liquid or gas then circulates back to the equipment in a continuous cycle, repeating the process and keeping the semiconductor equipment cool throughout production.

Why is Cooling Circuit Control Critical?

The semiconductor industry operates in extremely tight tolerances, and cooling circuit control is essential for several reasons:

Thermal Stability

Precise cooling prevents temperature fluctuations that can cause defects in wafers during semiconductor processing.

Equipment Longevity

Proper cooling reduces overheating, extending equipment life and minimizing breakdowns.

Improved Yield

Maintaining optimal temperatures improves product quality and reduces waste in semiconductor production.

Energy Efficiency

Automated systems optimize coolant flow, reducing energy use and operational costs.

Reduced Downtime

Automated cooling systems help prevent equipment failures, ensuring continuous production with minimal interruptions.
