CIRCOR Wet Etching Acid Filtration Project

CIRCOR Wet Etching Acid Filtration Project

In the manufacturing of semiconductors and electronic components, wet etching is a key step used to carve patterns onto wafers. This process uses strong acids to dissolve unwanted materials. However, if the acid contains even the smallest bits of debris, it can cause defects in the tiny circuits. The CIRCOR Wet Etching Acid Filtration Project is designed to keep these acids perfectly clean.

Why Clean Acid is Essential

During etching, tiny particles can fall off the wafer or come from the pipes. If these stay in the acid, they can land on a new chip and cause a short circuit. Our filtration system acts as a high-precision shield. It removes these contaminants in real-time, ensuring that the acid used in the machines is always pure. This leads to higher "yields"—meaning fewer wasted chips and more successful products.

The CIRCOR Advantage

• Acid-Proof Materials: Wet etching uses very "aggressive" chemicals. We use specialized plastics (like Teflon) and high-grade materials that do not melt or react with the acid, keeping the liquid pure.

• High-Temperature Stability: Many etching processes happen while the acid is very hot. Our filters are built to handle extreme heat without losing their shape or performance.

• Steady Flow: We ensure the acid flows at a constant speed by carefully balancing the pressure and the filter size. This keeps the production line moving without any sudden drops in performance.

• Simple Maintenance: Our systems are designed to be safe and easy for workers to change, reducing the time the machine needs to be turned off.
