Semiconductor Quartz bell jar

The Semiconductor Quartz Bell Jar from Semixlab is a high-purity quartz component designed for critical wafer processing applications, including CVD, PVD, plasma etching, diffusion, and ion implantation. Manufactured with ≥99.99% fused quartz, it provides a contamination-free, thermally stable, and chemically resistant environment essential for advanced semiconductor manufacturing.

Semixlab Semiconductor Quartz Bell is commonly used in the following semiconductor processes:

● CVD(Chemical Vapor Deposition)

Quartz bell jars provide a sealed, high-purity environment for chemical vapor reactions, ensuring uniform thin-film deposition. With excellent resistance to heat and corrosion, they minimize particle contamination, making them ideal for semiconductor-grade thin film growth.

● PVD(Physical Vapor Deposition)

During metal and dielectric deposition, quartz bell jars act as a vacuum enclosure, preventing cross-contamination and enabling stable vapor flow.This ensures consistent film thickness across wafers, a key factor in advanced semiconductor devices.

● Plasma Etching

Their dielectric properties make quartz bell jars compatible with RF-driven plasma processes.They prevent unwanted reactions with plasma gases, thereby guaranteeing precise etching profiles required for micro- and nano-scale patterning.

● Diffusion and Oxidation

In furnace applications, quartz bell jars withstand continuous high-temperature use (1200-1400°C). They provide a clean reaction atmosphere for dopant diffusion and wafer oxidation, ensuring uniform electrical characteristics of devices.

● Ion Implantation

Quartz bell jars function as protective enclosures in ion implanters. Their transparency, insulation, and chemical stability ensure that wafers remain uncontaminated while sensitive system components are protected from deposition.
