Short Type Quartz Glass Wafer Carrier Boat Custom Fabrication

Short Type Quartz Glass Wafer Carrier Boat 

1. Overview
The short Type quartz glass boat is a small quartz glass carrier designed specifically for silicon wafers in the semiconductor field, made of high-purity quartz glass. Its’ short version ‘refers to a shorter length, suitable for scenarios with limited space or small batch sample processing, commonly used in high temperature and precision experiments.

2. Material characteristics
High temperature resistance: It can withstand temperatures ranging from 1200 ℃ to 1500 ℃ (with slight differences in purity), has an extremely low coefficient of thermal expansion, and excellent thermal shock resistance.
Chemical inertness: Highly stable to acids, bases, and corrosive gases (except hydrofluoric acid and hot phosphoric acid), avoiding sample contamination.
High transmittance: Excellent transmittance in the ultraviolet to infrared wavelength range, suitable for experiments requiring optical monitoring.
Insulation: non-conductive, suitable for environments such as semiconductors that are sensitive to static electricity.

3. Application Fields
Semiconductor manufacturing: used for high-temperature treatment of silicon wafers in diffusion furnaces and oxidation furnaces.
Photovoltaic industry: a carrier in the coating and sintering process of solar cells.
Laboratory analysis: Sample support for experiments such as thermogravimetric analysis (TGA) and chemical vapor deposition (CVD).
Material processing: processes that require a clean environment, such as high-temperature annealing.

4. Design Features (Short term Advantage)
Compact and flexible: Suitable for small tube furnaces or limited space equipment, making it easy to quickly take and place samples.
Uniform heat distribution: Short sizes reduce temperature gradients to ensure process consistency.
Lightweight: reduces operational difficulty and is suitable for frequent experimental operations.

5. Precautions for use
Avoid mechanical impact: Quartz glass has high brittleness and should be handled with care.
Control temperature changes: Avoid sudden cooling and heating, it is recommended to increase/decrease the temperature rate by ≤ 5 ℃/minute.
Cleaning method: After use, use dilute hydrofluoric acid or deionized water for ultrasonic cleaning to avoid high-temperature sintering of residues.
Storage conditions: Place in a dry and dust-free environment to prevent surface contamination or scratches.

6. Comparison with other materials
Ceramic boat: Quartz has higher temperature resistance and higher purity, but lower mechanical strength.
Metal boat: Quartz has no risk of metal contamination, but it is not as impact resistant as metal.

Short quartz glass boats are an ideal choice for precision high-temperature processes due to their high temperature resistance, high purity, and chemical stability. Despite the need for caution to prevent damage, its crucial role in the fields of semiconductors, photovoltaics, and scientific research is irreplaceable. When selecting, appropriate specifications should be matched based on the temperature, size, and cleanliness requirements of the specific process.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
