Material Composition and Properties
The Wafer Carrier is constructed from high-quality graphite, which is known for its excellent mechanical strength and ability to withstand extreme thermal conditions. The SiC coating applied to the graphite provides additional layers of protection, making the component highly resistant to oxidation at elevated temperatures. The SiC coating also enhances the carrier's durability, ensuring it maintains its structural integrity under repeated high-temperature cycles and exposure to corrosive gases.
The SiC-coated graphite composition ensures:
· Excellent thermal conductivity: facilitating efficient heat transfer, essential during semiconductor epitaxial growth processes.
· High-temperature resistance: the SiC coating withstands extreme heat environments, ensuring the carrier maintains its performance throughout the thermal cycling in the reactor.
· Chemical corrosion resistance: the SiC coating significantly improves the carrier's resistance to oxidation and corrosion from reactive gases often encountered during epitaxy.
· Dimensional stability: the combination of SiC and graphite ensures the carrier retains its shape and precision over time, minimizing the risk of deformation during long process runs.
Applications in Semiconductor Epitaxy Growth
Epitaxy is a process where a thin layer of semiconductor material is deposited onto a substrate, typically a wafer, to form a crystal lattice structure. During this process, precision wafer handling is critical, as even minor deviations in wafer positioning can result in defects or variations in the layer structure.
The Wafer Carrier plays a key role in ensuring that semiconductor wafers are securely held and properly positioned during this process. The combination of SiC-coated graphite delivers the required performance characteristics for silicon carbide (SiC) epitaxy, a process that involves growing high-purity SiC crystals for use in power electronics, optoelectronics, and other advanced semiconductor applications.
Specifically, the Wafer Carrier:
· Provides precise wafer alignment: Ensuring uniformity in the growth of the epitaxial layer across the wafer, which is critical for device yield and performance.
· Withstands thermal cycles: SiC-coated graphite remains stable and reliable, even in high-temperature environments up to 2000°C, ensuring consistent wafer handling throughout the process.
· Minimizes wafer contamination: The high-purity material composition of the carrier ensures that the wafer is not exposed to unwanted contaminants during the epitaxial growth process.
In semiconductor epitaxy reactors, the Wafer Carrier is placed within the reactor chamber, where it functions as a support platform for the wafer. The carrier allows the wafer to be exposed to high temperatures and reactive gases used in the epitaxial growth process without compromising the integrity of the wafer. The SiC coating prevents chemical interactions with the gases, ensuring the growth of high-quality, defect-free material.
