Half Moon Components

Semicorex Half Moon Components are semi-cylindrical or segmented internal reactor structures commonly installed inside epitaxial reactors. Their unique geometry helps optimize gas distribution, thermal management, wafer positioning, and chamber protection during epitaxial growth processes.

The product shown features a precision-machined cylindrical structure with integrated internal support geometry, specifically designed to fit LPE-style chamber configurations. These components are typically manufactured from high-purity graphite and can be protected with advanced CVD silicon carbide (SiC) coatings to improve durability, purity, and chemical resistance.

In epitaxial reactors, component stability and cleanliness directly affect film uniformity, crystal quality, and wafer yield. Therefore, reactor internals must withstand aggressive chemical environments, rapid thermal cycling, and prolonged high-temperature operation without deformation or contamination.

Key Features of Half Moon Components

High-Purity Graphite Base Material

The reactor components are manufactured using high-density, high-purity isostatic graphite materials specifically selected for semiconductor applications. The low impurity content helps minimize contamination risks during epitaxial growth processes.

High-purity materials are essential for maintaining:

* Stable crystal growth

* Uniform epitaxial layers

* Low defect density

* Semiconductor-grade cleanliness

Advanced SiC Coating Protection

For demanding process environments, the graphite substrate can be coated with dense CVD silicon carbide. The SiC coating forms a highly protective surface layer with excellent adhesion and chemical stability.

The SiC coating provides:

* Superior corrosion resistance

* Reduced particle generation

* Improved wear resistance

* Enhanced oxidation resistance

* Longer service life

The coating also protects the graphite substrate from process gases and aggressive cleaning chemicals.

Excellent Thermal Stability

Half Moon Components operate in high-temperature epitaxial reactors where thermal consistency is critical. Graphite and SiC materials offer excellent thermal conductivity and thermal shock resistance, helping maintain stable chamber conditions during rapid heating and cooling cycles.

The excellent thermal performance contributes to:

* Uniform temperature distribution

* Reduced thermal stress

* Stable process repeatability

* Improved epitaxial layer consistency

Precision Machining Capability

Semicorex utilizes advanced CNC machining and precision manufacturing technologies to achieve tight dimensional tolerances and complex internal structures.

Accurate machining ensures:

* Proper reactor fitment

* Stable gas flow control

* Reliable wafer positioning

* Consistent chamber performance

Complex customized geometries can also be produced according to specific reactor designs.

Strong Chemical Resistance

Epitaxial processes often involve corrosive gases and harsh operating conditions. SiC-coated reactor components demonstrate excellent resistance to:

* Hydrogen

* Chlorine-containing gases

* Acid cleaning chemicals

* High-temperature oxidation

This chemical durability significantly extends component lifespan and reduces maintenance frequency.

Applications in Epitaxial Growth Systems

Half Moon Components are widely used in advanced epitaxial processing equipment for semiconductor manufacturing applications, including:

* Silicon epitaxy

* SiC epitaxial growth

* GaN epitaxy

* Power semiconductor manufacturing

* LED production

* Advanced wafer processing

* High-temperature CVD systems

Inside the reactor chamber, these components help optimize gas flow dynamics, maintain process uniformity, and protect critical chamber areas from thermal and chemical damage.
