Purpose & Applications<\/strong><\/h5>\n

This product is a quartz protective component designed specifically for semiconductor dry etchers. Made of high-purity Synthetic Polycrystalline Quartz (SPQ), it effectively shields the electrostatic chuck (ESC \/ E-Chuck) from high-energy ion bombardment during plasma etching, preventing direct damage to the expensive chuck assembly.
\nWith ultra-low particle generation and excellent chemical stability, it helps minimize contamination inside the process chamber and is one of the key components for maintaining process cleanliness and stability.<\/p>\n

What is Synthetic Polycrystalline Quartz (SPQ)?<\/strong><\/h5>\n

Synthetic Polycrystalline Quartz is an artificially manufactured quartz material formed by aggregating numerous micro-sized quartz grains. Compared with natural single-crystal quartz, SPQ features a more uniform structure, excellent thermal stability, and strong mechanical properties, making it ideal for demanding environments.<\/p>\n
