Fused Quartz Pedestal
Exceptional Thermal Management and Optical Properties Origining from High Purity Quartz
One of the most remarkable attributes of our fused quartz pedestal is its proficiency in maintaining a consistent temperature during processing. This capability is pivotal in creating an environment conducive to the precise deposition of thin films. The fused quartz pedestal achieves this by effectively blocking both heat and light, thereby stabilizing the thermal conditions around the wafer. This is particularly important in processes requiring stringent thermal control to ensure uniformity and quality.
The high purity quartz’s extraordinary heat resistance, combined with its low coefficient of thermal expansion, allows it to operate at temperatures reaching up to 1200°C without compromising its structural integrity. The thermal shock resistance of the fused quartz pedestal further enhances its durability, making it perfectly fit for high-temperature applications where rapid temperature changes are common.
High Purity Quartz Manufacturing in Controlled Environments
At Semicorex, the production of each fused quartz pedestal involves sophisticated thermoforming and welding techniques. These processes are conducted in cleanroom environments of cleanliness class 10,000 or higher, ensuring minimal contamination and adherence to the highest standards of purity . Following fabrication, each fused quartz pedestal undergoes rigorous cleaning with ultrapure water (18 MΩ), which guarantees that any residual impurities are removed, thus maintaining the high purity quartz’s inherent quality and performance.
Superior Optical Transmission and Electrical Insulation
Our fused quartz pedestal is renowned for its high transparency across a wide spectral range, extending from ultraviolet to infrared wavelengths. This broad-spectrum transparency of high purity quartz is crucial in applications that demand high optical clarity and minimal signal loss. Additionally, the high purity quartz exhibits high radiation resistance, suitable for environments where exposure to various forms of radiation is inevitable.
Furthermore, the fused quartz pedestal provides exceptional electrical insulation resistance. This is particularly beneficial in semiconductor manufacturing processes where electrical isolation is paramount to prevent cross-talk and electrical interference, thereby ensuring the integrity of the electronic devices being produced.

Rigorous Dimensional Accuracy and Chemical Stability Given by High Purity Quartz
To meet the exacting requirements of the semiconductor industry, Semicorex ensures that each fused quartz pedestal is machined to precise tolerances. The diameter tolerance is maintained at ±0.25mm, while the length tolerance is held at ±0.5mm. This precision engineering guarantees a perfect fit and reliable performance, which are critical in high-tech manufacturing environments where even the slightest deviation can lead to significant issues.
The chemical properties of the fused quartz pedestal are equally impressive. The high purity quartz exhibits outstanding chemical strength and purity, being chemically inert and highly resistant to a wide array of corrosive substances. This chemical stability ensures that the pedestal remains uncontaminated and does not react with any of the chemicals used in the wafer processing, thereby preserving the purity of the wafers.
Extensive Benefits and Industrial Applications
The comprehensive set of benefits offered by the high purity quartz, including the fused quartz pedestal's exceptional thermal and chemical properties, precise machinability, and superior optical and electrical characteristics of the high purity quartz, make it an invaluable component in the semiconductor industry. The high purity quartz's ability to withstand high temperatures and resist thermal shock while maintaining uniform processing conditions ensures that it meets the rigorous demands of modern semiconductor fabrication processes.
In summary, Semicorex’s Fused Quartz Pedestal stands as a testament to advanced materials engineering and precision manufacturing. The fused quartz pedestal provides unparalleled support and reliability for critical wafer processing tasks, contributing to the production of high-quality thin films and the overall efficiency of semiconductor manufacturing. The Fused Quartz Pedestal's superior properties make it an essential component in achieving excellence in the fabrication of next-generation electronic devices.
