Custom quartz wafer boat

A Quartz Wafer Boat—also known as a quartz wafer carrier, quartz annealing boat, or wafer boat bracket—is a precision-engineered component used to hold and transport silicon wafers during various semiconductor fabrication processes. These include oxidation, diffusion, LPCVD, and annealing. By ensuring wafers remain aligned and stable under extreme thermal conditions, quartz boats for semiconductor wafer processing are essential for achieving high-yield and defect-free device manufacturing.

Material Properties of Quartz Wafer Boats

At Semixlab, our custom quartz wafer boats are manufactured from high-purity fused quartz, which offers excellent mechanical stability, low thermal expansion, and superior resistance to chemical corrosion.

Key Physical Properties of Fused Quartz:

●Purity: > 99.99% SiO₂

●Thermal Expansion Coefficient: ~0.55 × 10⁻⁶ /°C (20–1000°C)

●Softening Point: ~1665°C

●Thermal Shock Resistance: Excellent, capable of withstanding rapid temperature changes

●Optical Clarity: High transparency in UV, visible, and IR ranges

Applications of Quartz Wafer Boats in Semiconductor Wafer Processing

Quartz wafer boats are integral to several critical steps in semiconductor manufacturing:

●Diffusion and Oxidation: During these processes, wafers are exposed to high temperatures and specific gases to create desired electrical properties or insulating layers. Quartz boats provide a stable and contamination-free environment for wafers in high-temperature furnaces.

●Annealing: As a Quartz Annealing Boat, they are used to heat wafers to high temperatures to repair crystal lattice damage caused by ion implantation, activate dopants, or relieve stress. The high purity and thermal stability of quartz ensure uniform heating and prevent contamination.

●Chemical Vapor Deposition (CVD): In CVD, thin films are deposited on wafer surfaces from a gas phase. Quartz wafer carriers maintain precise wafer positioning, crucial for uniform film thickness and quality.

●Cleaning and Storage: While not their primary function, quartz boats can also be used for specific cleaning procedures and provide safe, clean storage for wafers between process steps. Some designs might also incorporate a Wafer Boat Bracket for easier handling and integration into automated systems.
