Our high-purity quartz boats are specifically designed as substrate holders for demanding annealing and Chemical Vapor Deposition (CVD) processes. Crafted from 99.99% pure quartz, these boats ensure non-contamination and stable performance at operating temperatures up to 1200°C. Each boat is precisely sized (50mm x 12mm x 38mm) to securely hold up to five 8 to 10 mm substrates with 0.5mm thickness, fitting seamlessly into standard 2″ O.D. tube furnaces (e.g., GSL-1100X and OTF-1200X-S). Ideal for semiconductor manufacturing and advanced materials research requiring precise thermal treatment.

Exceptional High-Temperature Stability
Designed to operate at working temperatures up to 1200°C (with a soften point around 1730°C), this quartz boat maintains its structural integrity and performance even under extreme thermal conditions within various furnace types.
Ultra-High Purity for Contamination-Sensitive Processes
Made from 99.99% pure quartz, this boat ensures an inert environment, preventing any contamination of sensitive substrates during high-temperature annealing or CVD processes, critical for semiconductor and advanced materials industries.
Precision Substrate Holding & Positioning
Engineered to precisely hold up to five 8 to 10 mm substrates with 0.5mm thickness, ensuring accurate and consistent positioning during thermal treatments. This precise design is vital for uniform processing results.
Optimized for Annealing & CVD Applications
Specifically designed for annealing and Chemical Vapor Deposition (CVD) processes, this boat fits seamlessly into standard 2″ O.D. tube furnaces (like GSL-1100X and OTF-1200X-S), providing a dedicated and efficient solution for high-precision material processing.
Application Scenario
Semiconductor Wafer & Substrate Processing
Primarily used in diffusion, annealing, and Chemical Vapor Deposition (CVD) furnaces for the precise thermal treatment of silicon wafers, compound semiconductor substrates, or other sensitive materials, ensuring uniform processing and preventing contamination.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
This quartz boat is precisely designed to hold 8 to 10 mm substrates, typically with a thickness of 0.5mm. It has slots to securely accommodate a total of five such substrates, making it ideal for small-scale or precision processing of semiconductor wafers, optical components, or advanced material samples.
This quartz boat is specifically designed to fit into 2″ O.D. (Outer Diameter) tube furnaces. Examples of compatible models include GSL-1100X and OTF-1200X-S. While it’s designed for common furnace types, it’s always recommended to verify your furnace tube’s inner diameter to ensure a proper fit and optimal performance.
For sensitive high-purity processes like those in semiconductor manufacturing, the quartz boat should be cleaned thoroughly with appropriate cleaning agents (e.g., dilute acids or specialized quartz cleaning solutions) followed by extensive rinsing with deionized water. Avoid abrasive cleaning tools to prevent scratching. Regular inspection for any signs of wear or contamination is also recommended to maintain its performance and extend its lifespan.
