SiC Fingers

Semicorex SiC Fingers are specialized parts whose primary applications are in semiconductor processing equipment, specifically in wafer handling and support systems. Their primary function is to support or hold wafers in place during processes such as epitaxy, ion implantation, or thermal treatment, in which dimensional stability or cleanliness, along with reliability, is critical. Silicon carbide combines mechanical strength with excellent thermal and chemical resistance, and these characteristics are necessary in advanced semiconductor fabrication lines, so SiC Fingers are indispensable in such applications.

The selling feature of silicon carbide as a material is the ability to withstand extremely high operating temperatures without losing its mechanical integrity. In semiconductor processes such as epitaxial growth, wafers experience elevated temperatures suddenly and over extended periods. The SiC Fingers once engaged will maintain their alignment and strength throughout the high-temperature cycles so the wafers remain in place, minimizing movement to avoid deformation or misalignment to maintain adequate process uniformity to achieve acceptable device yield. SiC Fingers provide much longer service than typical ceramic or metal supports while being much more consistent in high-temperature loads.

A key benefit of SiC Fingers is their superior chemical resistance. All semiconductor applications involve reactive gases, exposure to plasmas, and exposure to corrosive chemicals. The corrodible or decayed material responds by releasing particles or contaminants that can degrade wafer quality. Silicon carbide has a chemically inert surface that will not attach or react to aggressive chemicals, producing a clean process environment and a significantly reduced risk of contamination. This adds to the durability of the wafer handling tool, directly contributing to stable and repeatable process results which is critical in producing semiconductor devices with high yield.

Precision is another key consideration in the design of the SiC Finger. Wafer handling entails components with extremely tight tolerances, micrometers can cause wafer misalignment, increase the potential for breaking the wafer, or cause inconsistencies in processes. By utilizing the latest in machining and polishing technology, SiC Fingers can be produced with theh highest dimensional tolerances and surface flatness and smooth finish. This guarantees a stable, relatively inertia free platform for wafer support with reduced potential for particle formation, and repeated performance of wafer handling applications in automatic semiconductor processing equipment.

In addition to the base material advantages of SiC Fingers, they can also be made specific to suit each equipment or process requirement. Different wafer sizes, different reactor designs, and different operator handling require specific manufactured solutions. SiC Fingers can be made in any geometry or dimension, and surface treatment can be applied as suitable for specific applications.

SiC Fingers also reduce operating costs, due to their long useable life (lowering frequency of replacement) and their reduced downtimes due to failure or deposition contamination from thermal or chemical stress. With both durability and reliability for semiconductor manufacturers, utilization of SiC Fingers leads to increased uptime, lower consumable cost, and overall improved process efficiency.

Practically, SiC Fingers are utilized mostly in epitaxy growth reactors, as they provide stable wafer holding during extreme thermal and chemical processes. They are also utilized in ion implanters or high temperature anneals where mechanical stability, as well as chemical inertness is critical. Across applications, consistent performance also makes their use in wafer handling critical in providing process uniformity, wafer integrity, and quality.
