Quartz boats are essential components in the semiconductor, photovoltaic, and laboratory industries. Made from high-purity quartz glass, they provide excellent thermal stability, chemical resistance, and durability in extreme environments.
Our quartz boats can withstand 1200°C for long-term use and 1450°C for short-term exposure, making them ideal for wafer processing, diffusion furnaces, and high-temperature experiments. In this article, we will explore their key features, applications, and how to choose the best quartz boat for your needs.
1. What is a Quartz Boat?
A quartz boat is a high-purity fused silica carrier used to hold semiconductor wafers, glass substrates, and other materials during high-temperature processing. These boats ensure precise handling and minimal contamination in CVD, oxidation, and diffusion processes.
Key Properties of Quartz Boats:
✔ High-Temperature Resistance – Long-term use at 1200°C, short-term at 1450°C
✔ High Purity (99.99%) – Essential for semiconductor and optical applications
✔ Chemical Stability – Resistant to acids and most chemicals
✔ Low Thermal Expansion – Reduces risk of cracking under rapid heating and cooling
✔ Precision Manufacturing – Custom sizes for different wafer diameters
